摘要: 脂氧合酶(lipoxygenase)是果蔬成熟衰老中的关键酶。我们从大豆中提取了脂氧合酶,在植物体外用酶反应动力学的方法进行了其活性抑制的研究,以便筛选出更多的抑制剂。结果发现:半胱氨酸、维生素C、TBHQ等抗氧化剂以及厚朴和白芍的95%乙醇提取液对脂氧合酶活性有较好的抑制作用。

Abstract: Lipoxygenase is a key enzyme in ripening and senescence of vegetables and fruits . Lipoxygenase was extracted from soybean and the inhibition of it’s activity was investigated so as to select more inhibitors with enzymatic kinetic methods in vitro. The results showed that cysteine、 vitamin C 、BHT 、 TBHQ and 95% ethanol extracts of HOUPU、BAISHAO etc had good inhibitory effect on lipoxygenase .
