印楝植物内生真菌Phomopsis sp.的代谢产物研究

Studies on the Metabolites of Endophytic fungus Phomopsis sp. from Azadirachta indica A.Juss

从印楝植物内生真菌Phomopsissp.的菌丝体提取物中分离得到4个化合物,通过波谱技术分别鉴定为水苏碱(1)、甲基-β-D-葡萄糖苷(2)、过氧化麦角甾醇(3)、腺嘌呤核苷(4),这些化合物均为首次从该属真菌中分离得到。

Four compounds were obtained from the mycelium of endophytic fungus Phomopsis sp. isolated from Aza- dirachta indica A. Juss. Their structures were identified as stachydrine （ 1 ）, methyl-β-D-glucopyranoside （ 2）, ergosterol peroxide（3） ,and adenosine（4） by spectral methods. All of them were isolated from the genus Phomopsis for the first time.
