摘要
应用二次通用旋转组合设计,对茶籽壳提取原花青素的参数进行研究。结果表明:提取时间(X_1),乙醇体积分数(X_2),提取温度(X_3),料液比(X_4)对原花青素的得率均有较显著影响,且呈现X_1>X_3>X_2>X_4。模拟优化后得到提取原花青素参数优化方案为:提取时间28 min,乙醇体积分数60%,提取温度55℃,料液比(g:mL)1:6。
By applying the combination design of quadratic rotational regression, the synthetically effects of extraction parameters of proanthocyanidins from episperm of tea （Camellia sinensis） seed were studied. Results showed that the effects of extraction time（X1）, concentration of ethanol（X2）, temperature（X3） and rate of solid to solution（X4） on extracting rate of proanthocyanidins from episperm of tea were remarkable, as in＇dicated by X1〉X2〉X3〉X4. The optimum parameters of extraction were as follows： extraction time 28 min, concentration of ethanol 60%（v/v）, temperature 55℃ and rate of solid to solution 1：6.
