摘　　要：以植物叶蛋白浓缩物为材料，用胰蛋白酶在不同条件下对其进行水解。结果表明，胰蛋白酶作用于植物叶蛋白，其最佳水解温度为４０℃；最佳水解ｐＨ值为９；水解程度随酶量和反应时间增加而增加；各种不同种类的植物叶蛋白在相同条件下被胰蛋白酶水解的程度基本一致，证明了植物叶蛋白易被动物体内蛋白酶分解。Under different conditions, the abstracts of the plant leaf proteins were hydrolyted by trypsin. The results showed that for hydrolysises the Optimal temperature was 40℃, and the Optimal pH valus was 9.0.The degree of hydrolysis was increased with amount of trypsin or reaction time. meamwhile, various leaf proteins were degraded uniformly by trypsin under the same candition, As demonstrates that plant leaf proteins could be hydrolyzed easily by proteinase from animal.
