摘　　要：以粳稻Ｈ１２９为材料，对稻米的脂解酶进行了研究。水稻脂解酶主要位于胚芽及盾片部分，它含有数种性质不同的同功酶；灭菌与不灭菌水稻脂解酶活性的变化曲线不一致；与前人的研究结论相反，我们在未萌发或休眠的米糠部分未检测出脂解酶活性。The rice lipase in japonica variety H 129 was studied. The results showed that the lipase of rice distribute in the plumule and the scutum, not in the endosperm, It consists of several kinds of isoenzyme, It is different of the lipase active curve between the sterilized and the unsterilized rice seed, Opposite to the results of previous study, no lipase activity was found in the ungerminated rice seed and the dormancy rice bran.
