Abstract: | Investigation of the constituents of whole herbs of Aster indicus L. led to isolation of 4-hydroxy-3-1-(methoxycarbonyl)vinyloxy]benzoic acid (1), 5-(1-carboxylvinyloxy)-2-hydroxybenzoic acid (2), 4-allyl-2,6-dimethoxyphenyl 3-methylbutanoate (3), and 4-allyl-2-methoxyphenyl 2-methylbutanoate (4), together with 27 previously known compounds. The structures of compounds 1-4 were established by application of spectroscopic (NMR and MS) analyses. |
