Ecological Distribution, Phytochemical Profiling, and Ex-Situ Conservation Strategies for Lesser-Known Medicinal Plants in the Agra District, India

Abstract

India represents one of the world's most significant mega-diversity centers, holding a vast reservoir of medicinal and aromatic plants that have formed the foundation of traditional healthcare systems for millennia. However, escalating urbanization, industrialization, and habitat loss, which currently depletes forest cover by 1-2% annually, pose severe threats to these invaluable botanical resources. This study undertakes a comprehensive ecological and phytochemical investigation of lesser-known medicinal herbs across diverse habitats (industrial, urban, suburban, rural, and wetland) within the Agra district of Uttar Pradesh, India. A total of 17 indigenous medicinal species, including Abutilon indicum, Boerhavia diffusa, Tribulus terrestris, and Barleria prionitis, were identified and meticulously documented through the establishment of a localized herbarium. Ecological assessments utilizing the Jaccard Similarity Index indicated high spatial homogeneity in plant distribution (index > 0.9375), though subtle micro-environmental variations influenced specific population densities. Preliminary phytochemical screenings of aqueous and methanolic extracts revealed a dominant presence of flavonoids and tannins, suggesting high antioxidant and anti-inflammatory potential, while alkaloids were largely absent, barring specific species like Tribulus terrestris and Ruellia tuberosa. Furthermore, an ex-situ conservation experiment conducted at a botanical garden demonstrated statistically significant improvements in reproductive capacity and seedling survivorship (p < 0.05), particularly in species like Barleria prionitis. The integration of morphological profiling, ecological mapping, and controlled cultivation highlights the urgent necessity for formalized conservation frameworks to protect these biological assets, ensuring their sustainable integration into modern pharmacological research and mitigating the pressures on wild populations.
