Popis: Sida spinosa Linn. (synonyms: S. alba L., S. angustifolia Lam., S. angustifolia Mill.), Malvaceae, is an annual erect, branched small perennial herb, which grows abundantly on cultivated fields, waste areas, road sides, and hotter parts of India. S. spinosa has been used in traditional medicine for a variety of therapeutic purposes as astringent, cooling stomachic and in nervous, urinary, and cardiac diseases. A high-performance thin-layer chromatography (HPTLC) method has therefore been established for quantification of kaempferol and apigenin in plant powder of S. spinosa Linn. Chromatographic separation was performed on silica gel plates with dichloromethane-methanol-formic acid 8.0:1.0:0.5 (v/v), as mobile phase. Detection and quantitation were performed by densitometry, with a deuterium lamp, at 340 nm. The responses to reference standards were linear in the concentration range 150–450 µg mL−1 for kaempferol and 50–150 µg mL−1 for apigenin. The relative standard deviation for instrumental precision, intra-assay precision, and intermediate precision was
