摘要: 采用色谱法从反柄紫芝的子实体中分离得到4个化合物,波谱学方法鉴定了它们的结构,分别为: cochlearol E(1)、cochlearol F(2)、ganocin A(3)和ganocin B(4)。其中化合物1和2是新化合物,化合物3和4系文献已报道的源自本菌子实体的多环芳香杂萜。化合物1、3和4均是外消旋体,对新化合物1进行了手性拆分并通过量子化学计算方法确定了其对映体的绝对构型。

关键词: 反柄紫芝, 灵芝科, 杂萜, 外消旋体, 绝对构型

Abstract: Two new meroterpenoids,termed cochlearols E (1) and F (2),along with two known meroterpenoids,ganocins A (3) and B (4) were isolated from the fruiting bodies of Ganoderma cochlear.The structures of the new compounds were identified on the basis of spectroscopic methods.In particular,compounds 1,3 and 4 were isolated as racemic mixtures,chiral separation of 1 followed by computational methods assigned its absolute configuration.

Key words: Ganoderma cochlear, Ganodermataceae, meroterpenoids, racemates, absolute configuration
