Texts state that the Sida cordifolia has analgesic, antispasmodic, anti-inflammatory, hypoglycemic and hepatoprotective properties. This species is found in tropical and subtropical regions of Sri Lanka and India. The aim of this study is to determine the phytochemical constituents of Sida cordifolia. phytochemistry helps in standardizing the herbal preparations and possibly relate the constituents to their medicinal/pharmacological uses. Dried material was grounded to coarse powder and stored in airtight container. It was then extracted with ethanol. The dry powder of sample was observed under U.V. light to evaluate the fluorescence. Chemical tests were performed on ethanol extract. The quantitative studies revealed that Sida cordifolia possessed alkaloids (1.99 mg/kg), flavonoids (0.92 mg/kg), lignin (0.08mg/kg), glycosides (0.19 mg/kg), saponins (0.17 mg/kg), phytosterols (0.02 mg/kg), fixed oils (0.18 µg/lit). Phytochemicals act in numerous ways to assist the human body in combating disease and health problems. The preliminary phytochemical screening tests may be useful in the detection of the bioactive principles and subsequently may lead to the drug discovery and development. It is also justify the traditional medical uses and the claims about the therapeutic values of this plant as curative agent. Further to this the isolation, identification, characterization and elucidation of the structure of the bioactive compounds of Sida cordifolia would be obtained with a view to obtain useful chemotherapeutic agent.
