摘要：

From the stem and root bark of Erythrina sigmoidea and E. eriotricha, one new prenylated flavanone, named sigmoidin L, and two new esters of ferulic and isoferulic acid, erythrinassinates C and D, were isolated together with eight known compounds, including one ester of isoferulic acid [3 beta-O-(E)-isoferuloyl oleanolic acid], one flavanone (sigmoidin A), four isoflavones (scandenone, 6,8-diprenylgenistein), flemiphilippinin B and 8-prenyldaidzein and two pterocarpans (gangetinin and calopocarpin). Their structures were elucidated by analysis of spectral data and chemical evidence. The in vitro anitmicrobial spectrum and potencies of the isolated compounds are also reported.
