【摘要】 用高效液相色谱分析方法，在碳十八柱上，以乙腈－异丙醇为流动相，分析了银杏、杉木、杨树叶中磷脂酰甘油的分子种组成。分析采用磷脂酰甘油经磷脂酶Ｃ水解后，用３，５－二硝基苯甲酰氯衍生，再进行高效液相色谱分离的方法。分子种根据文献的相对保留值、标样的实验保留值、分析样ＨＰＬＣ峰的脂肪酸组成分析而确定。分析结果表明，三种林木叶中磷脂酰甘油均主要由八个分子种组成，在八个分子种的相对含量上，树种间存在明显差异。更多还原

【Abstract】 Molecular species of phosphatidylglycerol in leaves of Ginkgobiloba, Chinese fir and Poplar were analyzed by HPLC on a C18 column with acetonitoile-2 -propanol (80 : 20,v / v) as mobile phase. 8 molccular species of PG were found in these 3 trees, they are (18:3/16:1(3t))PG. (18:3/16:0))PG. (18:2/16:1(3t))PG. (18:2/16:0)PG. (18:1/16:1(3t)PG, (16:0 /16:1(3t)PG, (18:1/16:0)PG, (16:0/16:0)PG, The relative amounts of these 8 molecular species in 3 bees are significantly different: (mol%) Ginkgo biloba, 30.5, 12.6, 1 7.9, 22.4, 0.2, 5.1 , 4.0, 5.3, Chinese fir, 6.4, 16.1, 1 1.5, 33.2, 0.3, 3.0, 19.8, 7.3, Poplar ,10.1, 10.6, 10.6, 14.1, 8.4, 22.3, 12.5, 11.3.更多还原
