Objective:To isolate and elucidate the constituents from the fruit dregs of Rhus chinensis. Methods:The constituents were isolated and purified by chromatography on silica gel, Sephadex LH-20, RP-Cls gel and recrystallization. The structures were eluci- dated on the basis of the chemical evidence and spectroscopic data. Results : Ten compounds were obtained :β-sitosterol( 1 ), morolic acid ( 2 ), (2S) -1 -O-heptatriacontanoyl glycerol( 3 ), α-monpalmitin ( 4 ), palmitic acid ( 5 ), gallic acid ( 6 ), methyl gallate ( 7 ), ...
