摘要
用垂直板聚丙烯酰胺凝的方法，研究了南果梨果皮、果肉、果心的多酚氧化酶同工酶的酶带特征．结果表明：采用 pH6.5磷酸缓冲液提取液、10%分离胶浓度对南果梨多酚氧化酶同工酶分离效果较好；南果梨果皮部位多酚氧化酶同工酶谱带最多，为7条．
The isoenzymes of polyphenol oxidase of Nanguoli's core,pulp and peel were studiedby means of the polyacrylamide gel vertical slab electrophoresis.Optimum conditions for sepera-tion of the isoenzyme of PPO was the pH 6.5 and the separating glue with concentration of 10%.The bands of peel was more than that of other samples.
