Microbial transformation of curcumol (1) by Cunninghamella blakesleana (AS 3.970) yielded six metabolites. On the basis of spectral data, their structures were elucidated as 14-hydroxy-9E curcumol (2), 10R,14-dihydroxy curcumol (3), 10S,14-epoxy curcumol (4), 10R,14-epoxy curcumol (5), 10S,14-epoxy-7,11-dehydrocurcumol (6), 10R,14-epoxy-7,11-dehydrocurcumol (7), respectively. Among them 2, 3, 6 and 7 are new compounds; 4 and 5, 6 and 7 are two pairs of epimers.
布氏小克银汉霉(AS 3.970)对莪术醇(1)进行微生物转化产生了6种代谢产物。根据光谱数据,确定它们的结构分别为14-羟基-9E莪术醇(2)、10R,14-二羟基莪术醇(3)、10S,14-环氧莪术醇(4)、10R,14-环氧莪术醇(5)、10S,14-环氧-7,11-去氢莪术醇(6)、10R,14-环氧-7,11-去氢莪术醇(7)。其中,2、3、6和7为新化合物;4和5、6和7分别为两对差向异构体。
