摘要
利用闪式提取法提取落叶松树皮中的原花青素。研究了乙醇体积分数、料液比、提取时间和提取温度对落叶松树皮中原花青素提取得率的影响。在单因素实验的基础上,运用正交实验对结果进行优化。结果表明,闪式提取法提取落叶松树皮中原花青素的优化条件为:乙醇体积分数为60%,料液比1∶25(g/mL),提取时间为4min,提取温度40℃。在此条件下进行验证实验,原花青素得率达11.42%。该方法操作简单、速度快、得率高,适用于落叶松树皮中原花青素的提取。
The flash extraction method was employed to extract proanthocyanidins from Larch Bark.The effect of different ethanol volume fraction, raw material to liquid ratio, extraction time, extraction temperature on the extract rate of proanthocyanidins were investigated.The orthogonal experiment was conducted on the basic of the single factor experiment.The results showed that the optimum extraction conditions were as follows：volume fraction of ethanol of 60%, raw material to liquid ratio of 1 ：25 （g/mL）, extraction time of 4min, extraction temperature of 40℃. Under such conditions,the yield of proanthocyanidins was 11.42%.The proposed method was simple and fast with high extraction efficiency,which could be applied to extracting proanthocyanidins from Larch Bark.
