Two new transformed sesquiterpenes of alantolactone by Mucor polymorphosporus were obtained. They were characterized as 3beta-hydroxy-11betaH-eudesm-5-en-8beta,12-olide (2) and 3beta,11alpha-dihydroxy-eudesm-5-en-8beta,12-olide (3), on the basis of spectral methods including 2D NMR. And product 3 was an unusual hydroxylation derivative of alantolactone at C-11.
通过多形毛霉得到了两个新的土木香内酯转化倍半萜。基于包括二维核磁共振在内的光谱方法，它们被鉴定为3β-羟基-11βH-桉叶-5-烯-8β,12-内酯（2）和3β,11α-二羟基-桉叶-5-烯-8β,12-内酯（3）。产物3是土木香内酯在C-11位的一种不寻常的羟基化衍生物。
