Abstract: The systematic investigation on alcohol extract of Capsella bursa-pastoris resulted in the isolation of 10 compounds by column chromatography on silica gel,Sephadex LH-20 and HPLC.Structural elucidation of 10 compounds were aided by chemical evidences and spectral analysis.Their structures were identified as benzoic acid (1),p-hydroxybenzoic acid (2),vanillic acid (3),Apigenin (4),guanine (5),adenine (6),uridine (7),adenosine (8),luteolin-7-O-β-D-glucopyranoside (9),apigenin-7-O-β-D-glucopyranoside (10).All compounds were isolated from this plant for the first time.
