Abstract Three new lignans, 2β-hydroxy-2α-3′,4′-dimethoxybenzyl-3α-3″,4″-methylenedioxybenzyl-γ-butyrolactone, 2β-acetyl-2α-3′,4′-dimethoxybenzyl-3α-3″,4″-methylenedioxybenzyl-γ-butyrolactone and 3′,4′-dimethoxybenzyl-3-3″,4″-methylenedioxybenzyl-2,3-dehydro-γ-butyrolactone, were isolated from the leaves of Bupleurum salicifolium . Three other lignans were identified as 2β-3′,4′-dimethoxybenzyl-3α-3″
摘要 三种新型木脂素,2β-羟基-2α-3',4'-二甲氧基苄基-3α-3",4"-亚甲二氧基苄基-γ-丁内酯,2β-乙酰基-2α-3',4'-二甲氧基苄基-3α-3 ″,4″-亚甲二氧基苄基-γ-丁内酯和3',4'-二甲氧基苄基-3-3″,4″-亚甲二氧基苄基-2,3-脱氢-γ-丁内酯是从柴胡叶中分离得到的。其他三种木脂素被鉴定为 2β-3',4'-二甲氧基苄基-3α-3",4"-亚甲基-二氧基苄基-γ-丁内酯、2β,3α-双(3',4'-二甲氧基苄基)-γ-丁内酯和 1-3',4'-二甲氧基苯基-2,3-萘并-γ-丁内酯。还获得了三萜桦木脑。
