【摘要】 利用索氏提取法对产于辽宁鞍山的巨峰葡萄籽中的油性成分进行了提取,用硫酸—甲醇法酯化后,对其进行了GC/M S分析。实验结果表明,用索氏提取法从鞍山巨峰葡萄籽中主要提取出6种脂肪酸,其中主要是亚油酸,而油酸和棕榈酸的含量相对于其它产地的葡萄有较大的区别,可以作为快速鉴定鞍山巨峰葡萄的依据。更多还原

【Abstract】 The fatty elements in Anshan Jufeng grape seed(in Liaoning Province)are extracted by Soxhlet extraction method,and sulfuric-acid-methanol method is used to make an analysis of the seed by GC/MS.The experiment result shows that six main fatty acids are extractd from Anshan Jufeng grape seed.In particular,the main part is linoleic acid,while the comtents of loeic acid and palmitic acid are greatly different from grapes produced in other places.The contents of loeic acid and palmitic acid can be used to determine whether the grape is Anshan Jufeng grape or not.更多还原
