The present study aims to standardize and evaluate bioactive profiling of Acalypha indica L. leaves through pharmacognostic parameters, phytochemical screening and High-Performance Thin Layer Chromatography (HPTLC) analysis. Comprehensive standardization was carried out using physicochemical constants, including moisture content, total ash, acid-insoluble ash, and extractive values, by pharmacopoeial guidelines. Macroscopic and Microscopic analyses confirmed key diagnostic features of leaves for identification and quality control profiling. Preliminary phytochemical screening of the ethanolic extract revealed the presence of bioactive constituents such as flavonoids, alkaloids, tannins, glycosides, and phenolic compounds. Antioxidant activity was assessed using in vitro assays including DPPH, ABTS, Superoxide, Hydroxyl radical, Nitric Oxide scavenging, and CUPRAC methods. The extract exhibited significant free radical scavenging potential, particularly in the CUPRAC and Superoxide assays. HPTLC analysis showed the best separation of bands at different retention factors (Rf) when using a solvent system of Toluene: Ethyl acetate: Glacial acetic acid in the ratio of (7:2:1 v/v/v). The quantitative estimation revealed that 10 mg of the ethanolic extract of Acalypha. indica L. contained 13.90 µg of kaempferol.
