目的:优选复方藤茶降脂颗粒的提取工艺,为今后的新药研究提供实验依据.方法:以出膏率与二氢杨梅素与荷叶碱的提取率为考察指标,采用正交试验法优选最佳提取工艺参数.结果:最佳提取工艺为加10、8、8倍量90％乙醇回流提取3次,每次1h、0.5h、0.5h.结论:研制优选的复方藤茶降脂颗粒提取工艺技术路线合理可行,为进一步开发中药藤茶降脂颗粒奠定了基础.

Objective：To investigate the optimized extraction processforcompound Tengcha Jiangzhi granules,and to provide an experimental basis for new drug development in the future.Methods：With extract yield and extraction rates of dihydromyricetin and nuciferineas the indices for evaluation,an orthogonal test was performed to identify the optimal extraction parameters.Results：The optimized extraction process was reflux extraction with 10,8,and 8 times of 90% alcohol for three times,and the duration of each time of extraction was 1 hour,0.5 hour,and 0...
