满山香中的联苯环辛二烯木脂素

满山香Schisandra propinqua(Wall.)Hook.f.et Thoms]为五味子科植物，云南民间代五味子药用^1]，由于从五味子科植物中已分离到不少保肝降酶，抗艾滋病毒，抗癌和PAF拮抗等活性成分，其研究受到重视^2-4]，主含满山香根和提取物的复方注射液曾在云南省几所医院临床用于治疗肺癌，但其研究仅分离鉴定了两个三萜 酸(2]，为进一步寻找有效成分，我们对满山香茎藤进行了研究，从中分得8种联苯环辛二烯木脂素，经波谱和分析鉴定它们的结构为：acetylgomisin R(1) angeloylgomisin R(2),gomisinA(3),gomisin B(4),gomisinN(5),gomisinO(6),6-O-benzoylgomosin O(7)和Schisantherin A(8),1为新化合物，2系首次从五味子属植物中分得，其它均为首次从满山香中分得。

Dibenzocyclooctadiene Lignans from Schisandra Propinqua

Eight dibenzocyclooctadiene lignans were isolated from the stems of Schisandra propinqua(Wall.)Hook. f. et Thoms. Their structures were elucidated as acetylgomisin R(1), angeloylgomisin R(2), gomisins A(3), B(4), N(5) and O(6), 6 O benzoylgomosin O(7) and schisantherin A(8) by spectral studies. Among them, compound 1 was a new one, compound 2 was discovered in the genus Schisandra for the first time and the others were originally isolated from Schisandra propinqua .
