白木香内生真菌枝顶孢属两菌株的挥发油成分

Volatile Oil Constituents of Two Acremonium Endophyte Isolates from Aquilaria sinensis

采用溶剂萃取法提取白木香内生真菌R1(Acremonium sp.)和R2(Acremonium sp.)的挥发油,经GC-MS联用技术进行分析,从R1和R2的挥发油中分别鉴定出20个和16个成分,均以油酸、亚油酸、棕榈酸等脂肪酸为主要成分,并且均含有1,8-桉叶油素、姜烯、芳姜黄烯等萜类成分。本研究首次报道白木香内生真菌的挥发油成分。

The volatile oils of endophyte isolates R1 （Acremonium sp.） and R2 （Acremonium sp.） from Aquilaria sinensis were extracted by solvent method. Twenty and sixteen ingredients were identified from the volatile oils of R1 and R2 by GC-MS, respectively. Fatty acids, such as oleic acid, linoleic acid, hexadecanoic acid etc., were the main components, whereas terpenoids like 1,8-cineole, zingiberene, ar-curcumene were also found in both oils. It＇s the first report about the volatile oil constituents of endophyte isolates from A. sinensis.
