摘要：

A new dihydroflavonol, eriotrinol, and a new prenylated flavanone, sigmoidin G, have been isolated from the stem bark of Erythrina eriotricha and E. sigmoidea, respectively. Their structures were established as (2R,3R)-5,4'-dihydroxy-3'-methoxy-6'',6''-dimethylpyrano [2'',3'': 7,6] dihydroflavonol and 5,7,5',4'',5''-pentahydroxy-6'',6''-di-methylpyrano [2'',3''4:3',4'] flavanone on the basis of spectroscopic means and chemical evidence. The previous known 4'-O- methylalpinumisoflavone, sigmoidin B and pentacyclic triterpene, erythrodiol, have been also isolated.
