Introduction The twenty-first century faces an escalating environmental crisis driven by biodiversity loss, deforestation, unsustainable resource extraction, and climate change (United Nations Environment Programme UNEP, 2023). These global challenges threaten the integrity of ecosystems and the services they provide, including clean air, fertile soil, water regulation and genetic diversity. As humanity seeks pathways toward sustainable development, the rediscovery and utilization of plant resources-especially those with strong ecological and Dr. Sarojbala Thokchom 148 biochemical significance have gained renewed attention (Singh et al., 2021). One such underexplored plant is Brassaiopsis bodinieri (H. Lev.), a species belonging to the family Araliaceae, which includes ecologically significant genera such as Aralia, Schefflera, and Panax. This genus is distributed across subtropical and montane regions of East and Southeast Asia, including China, Myanmar, Nepal and Northeast India. B. bodinieri is a small deciduous tree or large shrub characterized by palmately lobed leaves, rough bark and clusters of small flowers (Li et al., 2018). Traditionally, species of Brassaiopsis have been used in ethnomedicine for the treatment of rheumatism, pain, and inflammation (Nguyen & Vo, 2021). However, comprehensive phytochemical studies focusing on B. bodinieri remain limited, especially concerning its potential contribution to environmental sustainability. 2.1. Environmental and Socioeconomic Relevance of Indigenous Plant Species Local and indigenous plant species form the backbone of biodiversity-based economies, particularly in ecologically sensitive regions such as Manipur in Northeast India. This state, part of the Indo-Burma biodiversity hotspot, harbors an exceptional range of flora and fauna adapted to varied climatic and altitudinal conditions (Kumar & Devi, 2022). Within such ecosystems, plants like B. bodinieri play crucial ecological roles like stabilizing soil, contributing to nutrient cycling and providing habitat and food for various fauna. Beyond their ecological services, indigenous plants hold cultural, medicinal, and economic value for rural and tribal Environment And Sustainable Development Potential Of 149 communities. The sustainable use of these species supports livelihood diversification while promoting conservation ethics rooted in traditional ecological knowledge (TEK). In Manipur, community-based forest management and sacred groves have long integrated such principles, illustrating a model of coexistence between humans and the environment (Devi et al., 2019). Therefore, studying B. bodinieri not only deepens scientific understanding but also aligns with sustainable local development practices. 2.2. Phytochemical Studies and Their Environmental Implications Phytochemical screening serves as the foundation for understanding the biochemical and ecological functions of plants. Secondary metabolites such as alkaloids, flavonoids, terpenoids, saponins and tannins are biosynthesized by plants not merely for human medicinal value but as adaptive responses to environmental stresses like herbivory, UV radiation, pathogens, and pollutants (Harborne, 1998). For instance, phenolic compounds protect against oxidative stress; flavonoids function as UV filters and antioxidants; and saponins deter herbivores and microbial invasion (Ali et al., 2020). From an environmental sustainability perspective, such compounds have potential applications in green chemistry, bioremediation, and natural product-based industries. Phenolics and terpenoids can act as bio-sorbents for heavy metal ions; alkaloids can be utilized for eco-friendly pesticides; and resins may contribute to biodegradable material Dr. Sarojbala Thokchom 150 development (Kumari et al., 2022). Thus, the identification and sustainable exploitation of such phytoconstituents could provide both ecological and economic benefits. Despite these advantages, global research has disproportionately focused on a limited number of medicinal species such as Azadirachta indica, Withania somnifera, and Ocimum sanctum, while many indigenous plants, including B. bodinieri, remain scientifically undervalued. This study seeks to fill that gap by providing foundational phytochemical evidence and connecting it with sustainable development discourse. 2.3. Ecological Role of Brassaiopsis bodinieri in Sustainable Ecosystems Brassaiopsis bodinieri grows naturally in subtropical hill slopes, forest edges and moist temperate zones between altitudes of 1,000 to 2,000 meters. Its morphological traits particularly the broad palmately divided leaves which enable efficient photosynthetic performance and adaptation to varied light intensities. These features contribute to local carbon fixation and microclimate regulation, thereby supporting the stability of montane forest ecosystems (Zhang et al., 2020). Ecologically, B. bodinieri contributes to soil stabilization through its root system and helps retain soil moisture, reducing erosion risks in hilly terrains. The species also provides microhabitats for invertebrates and plays a role in nutrient cycling via leaf litter decomposition. From a sustainability perspective, promoting native shrubs like B. bodinieri in community forestry or agroforestry programs can enhance ecosystem resilience and carbon sequestration potential (Lal et al., 2021). Environment And Sustainable Development Potential Of 151 2.4. Linking Phytochemistry to Sustainable Development Goals (SDGs) The investigation of B. bodinieri holds direct implications for achieving several United Nations Sustainable Development Goals (SDGs), particularly: i. SDG 3: Good Health and Well-being, through potential applications in natural medicine and preventive healthcare; ii. SDG 12: Responsible Consumption and Production, by encouraging plant-based bioproducts as sustainable alternatives to synthetic chemicals; and iii. SDG 15: Life on Land, through biodiversity conservation and sustainable ecosystem management. The integration of phytochemical research with environmental planning ensures that local biodiversity is not only preserved but also utilized responsibly for community and national benefit. This intersectional approach can transform indigenous plant research into a catalyst for regional sustainability policies (UNEP, 2023). 2.5. Research Gap and Objectives While previous studies on the genus Brassaiopsis have identified triterpenoids and saponins with potential pharmacological activities (Nguyen & Vo, 2021), there remains limited literature on the species B. bodinieri in the Indian subcontinent. Most of the available data originate from Chinese or Vietnamese studies, with little focus on ecological correlations or sustainable development implications. Therefore, this study addresses the following key objectives: Dr. Sarojbala Thokchom 152 1. To conduct a preliminary phytochemical screening of B. bodinieri leaves using aqueous, methanol, and petroleum ether extracts. 2. To evaluate the diversity and distribution of secondary metabolites across different solvents. 3. To explore the ecological and environmental implications of the identified compounds in the context of sustainability. 4. To establish the potential role of B. bodinieri in community-based biodiversity conservation and green economy development in Manipur. Through these objectives, the research aims to bridge the gap between chemical ecology and environmental management, offering a model for integrating scientific data into sustainable resource planning. 3. Materials and Methods 3.1. Study Area and Ecological Context The present study was conducted using leaf samples of Brassaiopsis bodinieri (H. Lev.), collected from the hilly regions of Thoubal and Chandel districts of Manipur, India (24°18′ N to 24°45′ N latitude and 93°45′ E to 94°15′ E longitude). These areas represent a transitional eco-zone between the IndoMyanmar biodiversity hotspot and the sub-tropical forest belt of Northeast India. The region experiences a humid subtropical climate, characterized by annual rainfall ranging between 1,400-1,800 mm and average temperatures from 14°C in winter to 30°C in summer. The ecological conditions, moderate elevation, rich humus soils, and ample rainfall- Environment And Sustainable Development Potential Of 153 support dense vegetation cover and high biodiversity, making it an ideal site for the natural growth of B. bodinieri. Field surveys and ecological observations were conducted in early spring (February-March 2025), when the species exhibited maximum vegetative growth. This period also coincided with the time of optimal leaf biochemical activity, providing ideal samples for phytochemical screening. 3.2. Plant Identification and Authentication The plant was identified based on morphological and taxonomical features as Brassaiopsis bodinieri (H. Lev.), belonging to the family Araliaceae. The identification was authenticated by experts in the Department of Botany, South East Manipur College, Komlathabi, Chandel, with verification against specimens available at the Herbarium of the Botanical Survey of India (BSI), Eastern Regional Centre, Shillong. Voucher specimens were collected and deposited in the departmental herbarium for future reference (Voucher No.: SEMC/BB-2025/01). The identification followed classical floristic references such as “Flora of Manipur” (Deb, 1981) and “Flora of China” (Wu & Raven, 2004), ensuring scientific accuracy in species classification. 3.3. Collection and Preparation of Plant Material Fresh, mature, and disease-free leaves of B. bodinieri were collected manually using sterilized scissors to prevent mechanical injury and contamination. Collected leaves were washed thoroughly with distilled water to remove soil Dr. Sarojbala Thokchom 154 particles, dust, and other impurities, and then shade-dried at ambient temperature (25-30°C) for 10-15 days to preserve thermo labile compounds. After complete drying, the leaves were pulverized using a motar and pestle into a coarse powder and stored in airtight amber glass containers to avoid photodegradation and moisture absorption. 3.4. Extraction Procedures The extraction of phytoconstituents was carried out using three solvents-aqueous (distilled water), methanol, and petroleum ether-representing polar, semi-polar, and non-polar solvent systems, respectively. Approximately 50 g of the powdered sample was subjected to cold maceration with 250 mL of each solvent for 72 hours at room temperature with periodic shaking. After maceration, the extracts were filtered through Whatman No. 1 filter paper and concentrated under reduced pressure using a rotary vacuum evaporator at 40°C. The concentrated extracts were transferred to pre-weighed Petri dishes and airdried to constant weight. The percentage yield for each extract was calculated using the formula: Yield (%)=Weight of Extract / Weight of Plant Powder × 100 The dried extracts were stored at 4°C until further use for phytochemical screening. 3.5. Preliminary Phytochemical Screening Qualitative phytochemical tests were performed using standard protocols described by Harborne (1998) and Trease & Evans (2002). The screening aimed to detect the presence of Environment And Sustainable Development Potential Of 161 ecosystems where secondary metabolites play protective roles against oxidative and thermal stress. 4.5. Ecological and Environmental Interpretation The phytochemical profile of B. bodinieri reflects its adaptive response to the ecological conditions of the Northeastern Himalayan foothills. The abundance of antioxidant compounds such as flavonoids and phenolics may contribute to the species’ ability to withstand high humidity and fluctuating temperatures. Furthermore, these compounds can aid in soil restoration by improving organic carbon content when plant residues decompose. From an environmental sustainability standpoint, the identified phytochemicals open opportunities for green chemistry and natural resource-based industries. For example, saponins and tannins can be utilized for eco-friendly pest management and wastewater purification, while phenolic-rich extracts may serve as natural preservatives or antioxidants in food and cosmetic industries. 4.6. Statistical and Comparative Insight Though this study focused on qualitative screening, the distinct pattern of solvent response implies potential for quantitative estimation in future analyses. The comparative abundance of phenolics and flavonoids in methanol extract, along with the consistent detection of alkaloids and steroids across all solvents, indicates a rich metabolic network. Similar phytochemical patterns have been reported in other Brassaiopsis species, such as B. glomerulata and B. hainla, reinforcing the Dr. Sarojbala Thokchom 162 genus’s reputation as a bioresource of ecological and pharmacological importance (Chen et al., 2016; Balunas et al., 2009). 4.7. Summary of Key Findings In summary, the phytochemical screening confirmed that Brassaiopsis bodinieri (H. Lev.) is a phytochemically diverse species containing ecologically significant metabolites such as alkaloids, flavonoids, phenols, and steroids. The methanolic extract emerged as the most efficient solvent, capturing the broadest range of compounds. These findings underscore the species’ potential for sustainable utilization in pharmacological, agricultural and environmental conservation programs. 5. Discussion 5.1. Integration of Phytochemical and Ecological Insights The phytochemical screening of Brassaiopsis bodinieri (H. Lev.) demonstrated the presence of a broad array of secondary metabolites, particularly alkaloids, flavonoids, saponins, tannins, phenols, steroids and terpenoids. The abundance and diversity of these bioactive compounds are not only of pharmacological importance but also provide valuable clues about the species’ adaptive strategies to its environment. In ecological terms, the biosynthesis of such compounds reflects a dynamic defense mechanism against biotic and abiotic stressors-including herbivory, microbial infection and oxidative stress common in humid montane ecosystems of Manipur. Environment And Sustainable Development Potential Of 163 Secondary metabolites function as chemical mediators in plant–environment interactions. Alkaloids deter herbivores through toxicity; phenolics and tannins inhibit microbial growth; while terpenoids and flavonoids contribute to antioxidative defense and UV protection. Hence, the biochemical richness of B. bodinieri symbolizes its ecological resilience and role in maintaining forest health. The plant’s phytochemical constitution is a manifestation of evolutionary adaptation, enhancing its survival and ecological service functions such as soil nutrient recycling, canopy protection, and microhabitat stability. 5.2. Solvent Influence and Biochemical Diversity The variation in phytochemical composition among aqueous, methanolic, and petroleum ether extracts reveals the crucial role of solvent polarity in isolating specific classes of metabolites. Methanol, a medium-polar solvent, efficiently extracted a wide spectrum of both polar and semi-polar compounds like phenolics, flavonoids, alkaloids and saponins because of its ability to penetrate plant cell walls and dissolve diverse biochemical moieties. This aligns with studies by Edeoga et al. (2005) and Sofowora (1993), who reported methanol as an ideal solvent for comprehensive phytochemical profiling. The aqueous extract, on the other hand, yielded primarily polar compounds such as tannins, saponins and glycosides, demonstrating that water can act as an environmentally friendly solvent for primary screening and community-level applications. The petroleum ether extract, being non-polar, Dr. Sarojbala Thokchom 164 showed limited extractability, indicating a smaller proportion of lipophilic compounds like essential oils and simple terpenes in the leaf matrix. This solvent-dependent variation is significant for sustainable development. From a green chemistry perspective, identifying efficient, low-toxicity solvents such as water or ethanol could help in developing eco-compatible extraction protocols, minimizing the use of hazardous organic solvents. Such approaches align with the United Nations’ Sustainable Development Goal 12 (Responsible Consumption and Production), promoting safer resource utilization and waste reduction. 5.3. Comparison with Related Species and Literature The chemical profile of B. bodinieri corresponds closely with other species within the genus Brassaiopsis, including B. hainla, B. glaucus, and B. simplex, which are reported to contain similar secondary metabolites with notable pharmacological properties (Chen et al., 2016; Balunas et al., 2009). These species have been investigated for antioxidant, antimicrobial, and antiinflammatory activities, properties attributable to their rich polyphenolic and flavonoid content. The dominance of flavonoids and phenolics in B. bodinieri suggests potential use in combating oxidative stress-related diseases and environmental toxins. In environmental biotechnology, such compounds can be explored as natural antioxidants to mitigate pollution-induced oxidative damage in aquatic ecosystems. The consistent presence of alkaloids and steroids across all solvent fractions indicates the plant’s Environment And Sustainable Development Potential Of 165 biochemical stability and possible involvement in long-term ecological defense mechanisms. 5.4. Environmental and Sustainability Implications From an environmental sustainability perspective, B. bodinieri represents a dual-value resource: ecologically significant in forest ecosystems and economically valuable for its phytochemical potential. The species contributes to the maintenance of biodiversity by supporting pollinators and microbial symbionts, while its dense canopy structure aids in microclimate regulation and soil stabilization in sloped terrains. Utilizing such plants for local livelihood without ecological degradation exemplifies the principle of sustainable bioprospecting extracting natural compounds while conserving species diversity and ecosystem integrity. The leafbased extraction model adopted in this study ensures minimal harm to the plant population, thereby maintaining ecological balance and allowing natural regeneration. Furthermore, the biochemical traits of B. bodinieri can support eco-industrial innovation: i. Saponins from its leaves may serve as biodegradable surfactants, replacing synthetic detergents that contribute to aquatic pollution. ii. Tannins and phenolics can be employed in natural dyeing, leather tanning, and wastewater treatment processes due to their metal-chelating and antimicrobial properties. Dr. Sarojbala Thokchom 166 iii. Flavonoid-rich extracts can be integrated into organic agricultural formulations as pest deterrents or plantgrowth promoters. Such applications align with the goals of sustainable rural development, particularly in regions like Manipur, where local communities depend on forest resources. Promoting value addition through environmentally friendly processing can empower indigenous populations while protecting natural habitats. 5.5. Ethnobotanical and Cultural Dimensions Traditionally, members of the Brassaiopsis genus have been used in indigenous medicine across Northeast India, China, and Myanmar. Although documentation of B. bodinieri’s specific ethnomedicinal uses remains limited, related species such as B. hainla have been employed to treat rheumatism, inflammation, and liver disorders. This suggests a potential for rediscovering cultural botanical knowledge linked to B. bodinieri, reinforcing the integration of traditional wisdom with modern ecological science. Ethnobotanical recognition also enhances conservation interest. When local communities understand the medicinal and ecological value of a plant, they are more inclined to protect it. Thus, bridging scientific research and traditional practice can foster community-based conservation frameworks, ensuring the long-term survival of rare species such as B. bodinieri. 5.6. Climate Adaptation and Ecosystem Services The secondary metabolites observed especially phenolics, flavonoids, and terpenoids play crucial roles in the plant’s Environment And Sustainable Development Potential Of 167 climate adaptation mechanisms. These compounds protect cellular structures from temperature fluctuations, UV radiation, and oxidative stress, enabling B. bodinieri to thrive under diverse environmental pressures. The species therefore contributes indirectly to ecosystem stability by sustaining vegetation cover, preventing erosion, and supporting faunal diversity. In the context of global climate change, recognizing such adaptive species is vital for ecosystem restoration programs. Plants with high phytochemical resilience can be introduced into degraded landscapes to restore soil fertility and biodiversity. The ecological role of B. bodinieri thus extends beyond pharmacological value which represents a bioindicator of ecosystem health and resilience in Northeastern India. 5.7. Sustainable Research and Conservation Ethics This study adhered to the ethical guidelines of the Indian Biodiversity Act (2002) and the Convention on Biological Diversity (1992), emphasizing conservation-linked utilization. Ethical collection methods ensured that only limited mature leaves were harvested, leaving the plant population intact. This practice exemplifies the concept of “research for sustainability”, where scientific inquiry coexists with biodiversity preservation. Future phytochemical research should incorporate quantitative analyses such as HPLC, GC-MS, IR and NMR to determine exact concentrations of key bioactives. Additionally, assessing antioxidant and antimicrobial potentials under controlled conditions could validate B. bodinieri’s practical Dr. Sarojbala Thokchom 168 applications in pharmaceuticals and environmental biotechnology. 5.8. Synthesis and Broader Perspective In synthesis, the findings from B. bodinieri’s phytochemical screening underscore the interconnectedness of ecology, chemistry and sustainability. The plant’s biochemical diversity mirrors its ecological adaptability, while its potential applications offer pathways for sustainable industry and community welfare. Promoting responsible exploration of such species within the framework of conservation biology ensures that natural resources continue to support both environmental and human systems. Ultimately, the study of Brassaiopsis bodinieri (H. Lev.) serves as an exemplary model for how phytochemical research can inform sustainable development strategies linking molecular ecology with green innovation, traditional knowledge, and ethical environmental stewardship. 6.
