FOUR XANTHONES FROM FRUITS OF GARCINIA SCHOMBURGKIANA

Abstract

Garcinia schomburgkiana has been used as a traditional medicine in Asian countries. This plant is native to Vietnam. This study was done to investigate the phytochemicals of fruits of G. schomburgkiana grown in Tay Ninh Province. Four compounds α-mangostin (1), β-mangostin (2), fuscaxanthone A (3), and 9-hydroxycalabaxanthone (4) were isolated from the ethyl acetate extract of Garcinia schomburgkiana fruits. Their chemical structures were elucidated by comparing their spectroscopic data with reported data in the literature
