Phytochemical study of fissistigma polyanthoides (DC.) Merr. stem bark

Abstract

By means of chromatographic and crystallization techniques, two flavonoids, 6-hydroxy-5,7,8-trimethoxyflavanone (isopedicin) and 2’,5’-dihydroxy-3’-4’6’-trimethoxydihydrochalcone, and an alkaloid tetrahydroprotoberberine, 1,10-dihydroxy-2,3,9-trimethoxy-tetrahydroprotoberberine (capaurimine) were isolated from the stem bark of Fissistigma polyanthoides (DC.) Merr. The identification and structure elucidation of the isolated compounds were executed by analyses of the spectroscopic data. These compounds have never been reported to be found in this species before.
