【摘要】 以锦灯笼酸浆宿萼为原料,采用回流提取工艺研究了乙醇浓度、浸提时间、浸提温度和料液比对皂苷得率的影响。在单因素试验的基础上进行了正交试验,得到最优提取工艺组合为:80%的乙醇,60℃,120min,1∶9的料液比。此条件下总皂苷的得率为4.283mg.g-1。由方差分析可得,时间对皂苷提取率的影响差异不显著,故可缩短时间至105min。更多还原

【Abstract】 This study focused on the influences of ethanol concentration,extraction time,extraction temperature and liquid-solid ratio on the yield of total saponins from dried Physalis alkekengi calyx powder.Results of orthogonal test showed that the yield of saponins reached 4.283 mg·g-1 by using 80%(v) ethanol as solvent,liquid-solid ratio 9∶1 and temperature 60℃.Results of variance analysis showed that extraction time was non-significant at 5% probability level,so it can be shortened to 105 min.更多还原
