摘要
目的:建立白花檵木中没食子酸和总酚的最佳提取工艺。方法:以没食子酸和总酚含量为考察指标,筛选回流、渗漉、索氏、超声4种不同提取方法,正交试验优选溶媒、料液比、提取时间及提取次数4个工艺参数。结果:最佳提取工艺为采用回流提取法,8倍量60%乙醇提取3次,每次2 h。结论:采用该方法提取没食子酸和总酚,具有提取效率高、稳定性好等特点,适应于工业生产。
Objective：To establish optimal extraction technology of gallic acid and total polyphenols from loropetalum chinense.Method： With the content of gallic acid and total polyphenols as indexes,four different methods（refluxing extraction,leakage extraction,soxhlet extraction and ultrasonic extraction） were investigated,and orthogonal test was adopted to optimize extraction process parameters,including solvent,ratio of solid-liquid,extraction time and extraction times.Result： Refluxing extraction method was optimal extraction technology,optimum condition was as follow： 8 times the amount of 60% ethanol,extracted three times with 2 hours each time.Conclusion： This extraction process showed higher yield and good stability of gallic acid and total polyphenols,it was available for industrial production.
