木槿花中原花青素的提取工艺研究

Study on Extraction Procedure of Proanthocyandins from Hibiscus Syriacus Linn

以木槿花原花青素含量为考察指标,研究提取剂浓度、提取温度、提取时间、料液比等因素对原花青素提取效果的影响,通过正交实验,确定木槿花原花青素的最佳提取条件为:提取剂90%乙醇溶液,提取温度70℃,提取时间30 m in,料液配比1∶9(g∶mL).

The content of proanthocyandins from the flowers of Hibiscus syriacus Linn was regarded as the index of examination.This paper studied the concentration of ethanol,temperature,solid-liquid ratio and time of extraction as factors influencing the extraction.According to orthogonal test,the optimal extraction conditions of proanthocyandins were showed as follows:the concentration of ethanol was 90%,the temperature of extraction was 70 ℃,the time of extraction was 30 minutes and the solid-liquid ratio was 1∶ 9.
