Abstract
Begonia palmata (Bp) a medicinal herb with significant nutritional value, is globally consumed as a medicinal salad and traditionally used to treat inflammation, wounds, malaria, haematemesis, and amenorrhoea. Despite its prominence in floriculture, horticulture, and herbal medicine, standardization protocols for ensuring its quality and identity remain undeveloped. The present study aims to establish a report on the comprehensive plant monograph and standardization for Bp, following standard guidelines. A detailed evaluation of Bp leaves encompassed morphological, microscopical, physicochemical, and nutritional analyses. The leaves were subjected to successive solvent extraction using a Soxhlet apparatus to obtain hexane, chloroform, ethyl acetate, and methanol extracts, followed by aqueous extraction through maceration. These successive extracts were subjected to qualitative and quantitative phytochemical analysis, and their in vitro antioxidant and antimicrobial properties were assessed. Histological analysis of Bp leaf revealed diagnostic features such as non-capitate, multicellular, biseriate covering trichomes, anisocytic stomata, and spiral thickenings of xylem vessels. Nutritional profiling demonstrated a high calorific value (285.88 kcal/100 g) along with a significant total vitamin C (0.115 ± 0.02 g/100 g) and fibers (28.2 ± 0.98 g/100 g) content. Heavy metal analysis indicated that As, Cd, Cu, Pb, Hg, Sb, and Sn were within permissible limits, while Cr and Ni exceeded permissible limits. ICP-MS analysis confirmed the absence of pesticide residues. Phytochemical profiling revealed a high concentration of polyphenols, likely contributing to the observed antioxidant and antimicrobial activities. This study emphasizes the necessity of establishing quality control standards for Bp to support its global use in food, medicinal, and nutraceutical applications.
