摘要: 筛选制备高抑制血管紧张素转化酶(angiotensin converting enzyme,ACE)活性蜂王浆的酶制剂并确定其最佳酶解条件。在比较5种蛋白酶酶解蜂王浆产物抑制ACE酶活性基础上,选定日本天野公司生产的天野蛋白酶P为最适酶制剂,通过单因素试验和Box-Behnken二次旋转正交试验,并采用响应面分析得到天野蛋白酶P最佳酶解条件为水解时间196min、蜂王浆质量浓度0.0653g/mL、加酶量1503U/g。水解时间和蜂王浆质量浓度对抑制率有极显著影响(P<0.01),加酶量对抑制率有显著影响(P<0.05)。此条件下,蜂王浆酶解液对ACE的抑制率达到79.75%,为理论预测值的98.08%。蜂王浆几乎没有抗高血压活性,而天野蛋白酶P酶解蜂王浆产物有显著的抗高血压活性。

Abstract: Amano protease P was selected as the most suitable enzyme out of 5 proteases for preparing royal jelly-derived peptides with high angiotensinⅠconverting enzyme (ACE) inhibitory activity. Using one-factor-at-a-time method in combination with quadratic rotary orthogonal combination design, the optimal conditions for the hydrolysis of royal jelly by the selected enzyme for further improving ACE inhibitory rate of hydrolysates were 196 min, 0.0653 g/mL substrate concentration and 1503 U/g enzyme amount, resulting in an experimental ACE inhibitory rate of 79.75%, representing 98.08% of the theoretical value. Hydrolysis time and substrate concentration had extremely significant effect on ACE inhibitory rate of hydrolysates (P<0.01) and enzyme amount had significant effect (P<0.05). In conclusion, royal jelly almost has no ACE inhibitory activity, while royal jelly-derived peptides resulting from Amano protease P-catalyzed hydrolysis have powerful ACE inhibitory activity.

Key words: royal jelly, angiotensinⅠconverting enzyme (ACE)-inhibitory rate, protease, hhydrolysis, response surface analysis
