methyl esters of the predominant fatty acids in the lichen were identified: palmitic acid, linoleic acid, oleic acid and stearic acid; a hydrocarbon was also identified: 13-methyl-17-norkaur-15-ene and several derivatives of orsellinic acid. In the 1-Cires and 2-Cires fractions, the previous fatty acids were no longer observed, and only the derivatives of orsellinic acid were found. The analysis of the 1-Hexane
在这项工作中,我们对在阿尔及利亚采集的两份 Parmotrema hypoleucinum地衣样品的己烷、氯仿和乙醇提取物的化学成分进行了研究。地衣P. hypoleucinum的每个样品都收集在两个不同的支持物上:Olea europaea和Quercus coccifera. 在 Soxhlet 中制备己烷提取物;每种己烷提取物根据其在甲醇中的溶解度进行分级;分离(冷)溶于甲醇的产物:1-己烷、2-己烷;不溶于甲醇的产品(冷):1-Cires、2-Cires。用 GC-MS 分析了 1-Hexane、2-Hexane、1-Cires 和 2-Cires 的重氮甲烷酯化样品,其成分被鉴定为甲酯。在 1-己烷和 2-己烷馏分中,确定了地衣中主要脂肪酸的甲酯:棕榈酸、亚油酸、油酸和硬脂酸;还发现了一种碳氢化合物:13-methyl-17-norkaur-15-ene 和几种 orsellinic
