Abstract: 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%.
