Abstract Gnetin, a new stilbene isolated from Gnetum ula is assigned the structure 3,4-methylenedioxy-4′-methoxy- trans -stilbene, 3 on the basis of spectroscopic data and synthesis. The structure 3,3′,4-trihydroxy-2-methoxy- trans -stilbene, 1a earlier assigned to a trihydroxymonomethoxy stilbene is now revised to 3,4,5′-trihydroxy-3′-methoxy- trans -stilbene, 1b .
摘要 基于光谱数据和合成,从 Gnetum ula 中分离出的一种新的芪,Gnetin 被指定为结构 3,4-methylenedioxy-4'-methoxy-trans-stilbene, 3。先前分配给三羟基单甲氧基二苯乙烯的结构 3,3',4-三羟基-2-甲氧基-反式-二苯乙烯,1a 现在修改为 3,4,5'-三羟基-3'-甲氧基-反-二苯乙烯,1b。
