An HPTLC method is reported for estimation of lupeol and beta-sitosterol in the whole plant powder of Asteracantha longifolia (Acanthaceae). The proposed method was also employed for estimation of beta-sitosterol in herbal formulation containing Asteracantha longifolia. Methanolic extracts of the sample were used for chromatography. HPTLC on silica gel with toluene - ethyl acetate - methanol 75:15:7. Derivatization with Liebermann-Burchard reagent. Densitometric quantification at 366 nm. The concentration of lupeol and beta-sitosterol was 0.162 mg/g and 0.045 mg/g, respectively in the whole plant, while the concentration of beta-sitosterol was 0.039-0.048 mg/g in the formulation. The method was suitable for the quality control of the herbal formulation.
