| 摘 要： | 采用φ(硫酸)=1%的甲醇溶液酯化法(方法1)和酸碱结合甲酯化法(方法2)分别对红树林内生真菌Paecilomyces sp.(Tree1-7)代谢产物的石油醚部位衍生化,用气相色谱-质谱法分析鉴定了其成分,测定了各成分的相对质量分数。两种方法鉴定出共有主要脂肪酸成分6种,分别为9,12-十八碳二烯酸、棕榈酸、硬脂酸、顺-9-十八碳烯酸、12-甲基-十四烷酸和Cyclopentaneundecanoic acid。其中9,12-十八碳二烯酸为红树林内生真菌Paecilomyces sp.(Tree1-7)石油醚部位的主要成分,其相对质量分数达56%以上。但两种方法所得微量脂肪酸种类存在差异,方法1共检测到13种,其中微量脂肪酸7种,而方法2能检测到17种,其中微量脂肪酸11种。与φ(硫酸)=1%的甲醇溶液酯化法相比,酸碱结合甲酯化法所得脂肪酸成分更为全面。

| Abstract: | Two different esterification methods were employed to analyze the contents of fatty acid from the mangrove endophytic fungus Paecilomyces sp.(Tree1-7) by GC-MS,and the results showed that the main fatty acid components from fungus Paecilomyces sp.(Tree1-7) with two different esterification methods were identified,which are 9,12-octadecadienoic acid,hexdecanoic acid,octadecanoic acid,9(Z)-octadecenoic acid,12-methyl-tetradecanoic acid,cyclopentaneundecanoic acid and 9,12-octade-cadienoic acid had the largest... |
