Phytochemical study on medicinal plant- Sida cordifolia Linn

Abstract

Medicinal plants form the major source of drugs in all the traditional systems of medicine practiced in Sri Lanka, India viz., Siddha, Ayurveda, Unani and Homeopathy. There is a growing importance in medicinal plants and traditional health systems providing health care for a wider population across the globe, especially, in the developing countries. Sida cordifolia Linn is belonging to the family Malvaceae. Text states that the Sida cordifolia has analgesic antispasmodic anti-inflammatory, hypoglycemic and hepatoprotective activities. 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. The matured areal parts of Sida cordifolia were collected during the month of July-august 2012 from Jaffna, Sri Lanka.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. Sida cordifolia showed the presence of alkaloids, glycosides, phytosterol, flavonoids, lignins, protein and saponins. The quantitative studies revealed that Sida cordifolia possessed alkaloids (1.99mg/kg), flavonoids (0.92mg/kg), lignin (0.08mg/kg), glycosides(0.19mg/kg), saponins (0.17mg/kg), phytosterols (0.02mg/ kg), fixed oils (0.18 ?g/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. The Sida cordifolia studied here can be seen as a potential source of useful drug. 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.
