摘要
本文首次报道枇杷种子中存在Ｄ－半乳糖并建立了枇杷组织中５种糖的简易测定方法。采用大口径毛细管柱对枇杷组织中存在的Ｄ－果糖、Ｄ－半乳糖、Ｄ－葡萄糖、Ｄ－山梨醇、蔗糖等５种糖进行定量分析。本方法对各组分的线性相关系数ｒ均大于０．９９９；变异系数ＣＶ均小于３％；对山梨醇的平均回收率为９８％。
This article first reported the existence of D-galactose in loquat seeds and the establishment of a brief determining method for five kinds of carbohydrate in loquat constitute, i. e. D-Fructose, D-Galactose, D-Glucose, D-Sorbitol and Sucrose. The quantitative analysis was carried out through a large-bore capillary column. This methed more than 0. 999 the linear correlation coefficient for each analysed componence, less than 3% the coefficient of variation and the average recovery of D-Sorbitol reaches 98%.
