Phytochemicals have gained increasing attention during the last decade due to their biological significance and potential health effects, such as antioxidant, anticancer, anti-ageing, antiatherosclerotic, antimicrobial, see more and anti-inflammatory activities. Experimental and epidemiological studies have suggested that regular intake of some phytochemicals has been associated with reduced risks of chronic diseases, such as cancer, heart disease, and diabetes. Because of their ubiquity, abundance and low cost,
many phytochemicals have been isolated and identified from natural botanical sources such as fruits, vegetables, spices, cereals, and medicinal herbs.2 For this reason, medicinal plants have become the focus of intense study in recent years to determine whether their traditional uses are supported by actual pharmacological effects or are merely based on folklore. With the increasing acceptance by Western health-systems of traditional medicine as an alternative form of health care, there is an urgent need for an evaluation of traditional methods of treatment. Considerable importance has been placed on the screening of medicinal plants
for active UMI-77 compounds.3 Determination of extractive values and ash residues plays a significant role for standardization of the indigenous crude drugs.4 Most species (∼2500) of the relatively large acanthaceae family grow primarily in tropical areas as shrubs or herbs among 250 genera of considerable biological variety. The families of acanthaceae found application in African
and Indian primitive medicine isothipendyl for problems to a treatment for cancer, heart disease, gonorrhoea, and snake-bite.5 Dipteracanthus patulus (Jacq.) Nees. (Syn. Ruellia patula Jacq). (Acanthaceae) is a medicinal herb traditionally used in the treatment of wounds in the rural areas. The leaves are used for treating itches, insect bites, paronychia, venereal diseases, sores, tumours, rheumatic complaints and eye diseases. It is cardiotonic and single drug remedy for against the deadly poison of kaduva chilanthi (Tiger Spider) by kani tribes in agasthiarmalai. 6 and 7 The methanolic extract of D. patulus (Jacq.) Nees has shown promising antimicrobial and hepatoprotective activity. Leaves of this plant are used to cure liver complaints by the peoples of Sholapur region (MS), India. 8 Hence the present study focuses on the investigation of physiochemical parameters and to identify and quantify Stigmasterol from the leaves of D. paulus using High performance liquid chromatography. The fresh whole plants of D. patulus were collected from Coimbatore District, Tamilnadu, India. The Specimen was identified and authenticated by Joint Director, Botanical Survey of India, Southern Regional Centre, Tamilnadu Agricultural University, Coimbatore with specimen number BSI/SC/5/23/09-10/tech-1174. Fresh leaves of D. patulus were cleaned, shade-dried and powdered using the mechanical grinder.
