The study of the chemical constituents of the whole plant of Erigeron bonariensis (L.) has resulted in the isolation and characterization of a new and nine known compounds. The known compounds were identified as stigmasterol (1), freideline (2), 1, 3-dihydroxy-3R,5R-dicaffeoyloxy cyclohexane carboxylic acid methyl ester (3),1 R ,3R-dihydroxy-4S,5R-dicaffeoyloxycyclohexane carboxylic acid methyl ester (4), quercitrin (5), caffeic acid (6), 3-(3,4-dihydroxyphenyl)acrylic acid 1-(3,4-dihydroxyphenyl)-2-methoxycarbonylethyl ester (8), benzyl O-β-D-glucopyranoside (9), and 2-phenylethyl-β-D-glucopyranoside (10). The aromatic glycoside, erigoside G (7) is reported as new natural compound. The above compounds were individually identified by spectroscopic analyses and comparisons with reported data. The chemotaxonomic studies of isolated compounds have been discussed.
