  摘要：

  从药用真菌樟芝Antrodia camphorata的子实体中分离出十二种麦角类固醇，称为antcamphins A–L（1 – 12），以及20种已知的三萜类化合物。化合物1和2代表从樟脑曲霉中分离出的降冰片烷的第一个例子，化合物3和4是含醛基的麦角甾烷型三萜类化合物的第一对顺式-反式异构体。化合物5 – 12是四对C-25差向异构体。1 – 12的结构在广泛的光谱数据分析（包括NMR和HRESIMS）的基础上进行了阐明。特别是，通过改进的Mosher方法确定了C-25中5 – 12的绝对构型。这些三萜类化合物对MDA-MB-231乳腺癌细胞和A549肺癌细胞显示出弱的细胞毒活性，但在磺基罗丹明B试验中并未抑制正常细胞的生长。

  The bacterial glycosyltransferase YjiC1 was used to glycosylate triterpenoids from the medicinal fungus Antrodia camphorata. Eleven new compounds were obtained from enzymatic reactions. Glucosylation could increase the inhibitory activities against COX-2, and improve the anti-inflammatory activities of Antrodia ergostanes on acute lung injury mice, especially (25R)-antcin C 7-O-β-D-glucoside.

  Twelve ergostanoids, named antcamphins A–L (1–12), together with 20 known triterpenoids, were isolated from fruiting bodies of the medicinal fungus Antrodia camphorata. Compounds 1 and 2 represent the first examples of norergostanes isolated from A. camphorata, and compounds 3 and 4 are the first pair of cis–trans isomers of ergostane-type triterpenoids containing an aldehyde group. Compounds 5–12
