Abstract From the leaves of Bupleurum salicifolium two benzylidene-benzyl-γ-butyrolactone-type lignans were isolated. One was identified as kaerophyllin, the other as its cis-isomer, hitherto unreported. The latter was characterized as 2(3,4-dimethoxy)-benzylidene-3-(3,4-dioxymethyl)-phenylmethyl-3 S-γ-butyrolactone by spectroscopic chemical methods, and from a study of its derivatives.
摘要 从柴胡叶中分离得到两种苄叉-苄基-γ-丁内酯型木脂素。一种被鉴定为岩藻素,另一种被鉴定为顺式异构体,迄今未见报道。通过光谱化学方法和对其衍生物的研究,后者被表征为 2(3,4-二甲氧基)-苯亚甲基-3-(3,4-二氧甲基)-苯基甲基-3 S-γ-丁内酯。
