Three pyrrole alkaloids were isolated from Bolbostemma paniculatum. Their structures were elucidated as 4-(2-formyl-5-methoxymethylpyrrol-1-yl)butyric acid methyl ester (1), 2-(2-formyl-5-methoxymethylpyrrol-1-yl)-3-phenylpropionic acid methyl ester (2) and alpha-methyl pyrrole ketone (3) by spectroscopic techniques. Among them, 1 and 2 are new compounds.
