紫果猕猴桃嫩枝多酚氧化酶活性与总酚含量变化
Dynamics of Polyphenol Oxidase (PPO) Activity and Total Phenol Content of Actinidia arguta var. purpurea Shoots
摘要
Abstract
Using the twigs and petioles of Actinidia arguta var. purpurea as test materials, the polyphenol oxidase (PPO), total phenol content, and their change pattern were analyzed. The results showed that, the suitable pH value for determining A. arguta var. purpurea PPO activity was 7.0, the optimal substrate was oxophenic acid, with the concent of 0.16 mol/L, and the optimum temperature was 25 °C. The PPO activity of A. arguta var. purpurea at growth phase was higher than at dormancy stage. The total phenol content of A. arguta var. purpurea was the minimum in April, May and September.关键词
