摘要
对水提取绞股蓝超微粉总皂苷的工艺条件进行了研究。在提取过程中,通过单因素试验分析了粉碎度、浸提温度、浸提时间和固液比对提取率的影响。并通过正交试验,对乙醇提取绞股蓝超微粉总皂苷的工艺条件进行了优化。试验表明,最佳提取工艺条件为绞股蓝粉碎粒度D503.03μm,料液比(g∶mL)1∶15,提取时间30min,提取温度70℃,绞股蓝总皂苷提取率为4.35%。
The effect of super fine crushing on the extraction of flavonoids in Gynostemma was studied in this paper, through the single-factor analysis of the crush, extraction temperature, extraction time and solid-liquid ratio on the extraction rate of impact. On the basis of a single factor, by orthogonal test, the ethanol extract of the total saponin gypenosides superfine powder has been optimized process conditions, tests showed that the best conditions for the extraction of D50 gypenosides crush size for the 3.03 μm, feed than （g ： mL） to 1：15, from time to 30 min, extraction temperature for 70℃, Gynostemma total saponin extraction rate for 4.35 percent.
