Comparative Phytochemical Profiling and Pharmacological Evaluation of Underutilized Edible Wild Plants for Nutraceutical Applications

Project Abstract

Underutilized edible wild plants hold untapped potential as sources of nutraceuticals due to their rich phytochemical diversity and diverse pharmacological properties, which can contribute to functional foods, preventive healthcare, and sustainable food systems. This study undertakes a comprehensive phytochemical profiling and pharmacological evaluation of selected underutilized edible wild plant species to establish their nutraceutical value, safety, and mechanism of action. A multidisciplinary approach was adopted, integrating metabolomic fingerprinting, quantitative phytochemical analyses, and in vitro and in vivo assays. Target species were selected based on ethnobotanical use, availability, and preliminary evidence of bioactivity. The phytochemical analysis employed high-performance liquid chromatography coupled with diode-array detection and mass spectrometry (HPLC-DAD-MS/MS) to quantify major classes such as polyphenols, flavonoids, alkaloids, terpenoids, and glucosinolates, complemented by untargeted metabolomics to capture novel compounds. Multivariate statistical methods, including principal component analysis and hierarchical clustering, revealed distinct phytochemical profiles linked to taxonomic groups and ecological origin. Pharmacological evaluations focused on antioxidant, anti-inflammatory, anticancer, antimicrobial, and metabolic-modulatory activities, employing standardized in vitro assays (e.g., DPPH, ABTS, FRAP, COX-2 inhibition, NF-?B signaling, cytotoxicity against cancer cell lines, and antimicrobial MIC/MBC determinations) and ex vivo models where applicable. In vivo validation utilized a rodent model of oxidative stress and inflammation to corroborate in vitro findings and to assess pharmacokinetics, bioavailability, and safety parameters, including hepatic and renal function markers. The study also examined synergy among phytochemicals using combination index methods to identify potential additive or synergistic interactions that enhance efficacy at physiologically relevant concentrations. Data integration through network pharmacology linked identified phytochemicals to molecular targets and pathways related to oxidative stress, inflammation, metabolic disorders, and cancer, providing a systems-level understanding of mechanism of action. Results demonstrated that several underutilized species possess high total phenolic and flavonoid contents with potent Radical-scavenging and metal-chelating activities, as well as significant COX-2 and NF-?B inhibitory effects. Notably, extracts from certain species exhibited selective cytotoxicity against tumor cells with minimal effects on non-tumorigenic cells, suggesting favorable safety margins. Antimicrobial activity was observed against multi-drug resistant strains for specific extracts, potentially attributable to unique alkaloids and terpenoids identified in the metabolomic analysis. In vivo studies confirmed anti-inflammatory effects and improved oxidative stress biomarkers, with acceptable tolerability. The integration of phytochemical data with pharmacological outcomes highlighted key bioactive compounds and proposed biosynthetic pathways contributing to observed activities. The findings underscore the potential of these underutilized wild plants as sources of nutraceuticals with multitargeted actions, supporting their inclusion in functional foods, dietary supplements, and ethnomedicinal formulations. Challenges related to standardization, scale-up cultivation, and regulatory compliance were addressed, and recommendations for future work include cultivar-environment optimization, long-term safety assessment, and human clinical trials to translate preclinical efficacy into practical health-promoting products.
