云南美登木内生真菌Beauveria Sp．Lr89中的两个环肽

摘要

Endophytic fungus Lr89 was isolated from Maytenus hooked 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 13 C NMR data of compounds 1 and 2 were reported for the first time.%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.
