从南极真菌C3368菌株(疣状金孢霉Chrysosporium verrtucosum Tubaki)的发酵液中,分离得到两个活性成份C3368-A和C3368-B 。根据其理化性质和光谱学数据的分析,确定了C3368-A为Bisdechlorogeodin,C3368-B为Questin,并用CD谱确定了Bisdechlorogeodin的立体构型。
Two active ingredients C3368-A and C3368-B were isolated from the fermentation broth of the Antarctic fungus C3368 strain (Chrysosporium verrucosum Tubaki). According to its physico-chemical properties and spectroscopic data, C3368-A was identified as Bisdechlorogeodin and C3368-B as Questin. The stereo configuration of Bisdechlorogeodin was determined by CD spectra.
