Alkaloids, diarylheptanoid and naphthalene carboxylic acid ester from Rhoiptelea chiliantha

Abstract

Two pyrrolidine alkaloids (1, 2) were isolated from the fruits of Rhoiptelea chiliantha Diel et Hand.-Mazz. (Rhoipteleaceae). A diphenyl ether-type diarylheptanoid (3), and a naphthalene carboxylic acid methyl ester (4) which is biogenetically-related to juglone were isolated from the branches of the same plant. Their chemical structures were elucidated on the basis of spectroscopic analysis and chemical evidence.
