  Objective In the present study, the plant Chamaecrista nigricans (Siruavuri in Tamil) was selected to isolate, elucidate and identify the chemical constituents present in it. Methods Leaves were collected, shade-dried, coarsely powdered using a pulvarizor, successively extracted with various solvents of increasing polarity such as hexane, chloroform and methanol using Soxhlet apparatus. Methanol leaf extract was used for isolation and identification of chemical constituents. Column chromatography (CC) and thin layer chromatography (TLC) were used for separation and purification of chemical constituents while the isolated pure compounds were identified using UV-VIS, IR, 1H and 13C NMR spectra. GC-MS analysis was carried out to identify the chemical constituents. Results Three anthraquinones s.. View More»
