摘要
目的:优化中药五倍子中鞣质的提取方法。方法:以鞣质水解后没食子酸提取率为指标,用高效液相色谱法进行含量测定,采用L9(34)正交设计试验,对药材粒度、提取溶剂倍量、提取时间和提取次数等因素进行考察,以确定最佳提取工艺。结果:用10倍量水,提取3次,每次9h的方法可以获得较高的鞣质提取率。结论:优选得到的鞣质提取工艺鞣质提取率较高且稳定可行。
AIM: To optimize the extraction process of tannins from Galla Chinensis. METHODS: Using of HPLC to assay tannins hydrolysis, gallic acid as the content index was analyzed by HPLC, the optimum extraction condition consisted of extraction temperature, the size of material, the solvent extraction times and the extraction time by orthogonal test design. RESULTS : The best condition of extraction process was 10 times the volume of water, extracted three times, 9 hours each time. CONCLUSION: The optimized process is feasible for the extraction of tannins.
