摘要: 从云南美登木(Maytenus hookeri Loes.)的根部分离到内生真菌Lr89,根据ITS序列分析,鉴定为白僵菌属(Beauveria)真菌。在PDA琼脂平板发酵物中分离得到2个环肽类化合物,经波波谱鉴定为isaridin A(1)和isariin B(2),本文首次报道了这两个化合物的13C NMR数据。

Abstract: Endophytic fungus Lr89 was isolated from Maytenus hookeri and identified to be Beauveria by ITS sequence. Two cyclopeptides were isolated from PDA solid cultures of Beauveria sp. Lr89. They were determined to be isaridin A (1) and isariin B (2) on the basis of spectroscopic analysis, and the 13C NMR data of compounds 1 and 2 were reported for the first time.

Key words: Maytenus hookeri, endophytic fungus, Beauveria sp.Lr89, cyclopeptides
