ABSTRACT
This study was aimed to establish the determination method of total saponins content in Jiu-Bi-Y ing Y i-Xin (JBYYX) tablet. The content of total saponins in JBYYX tablet was determined by ultraviolet spectrophotometry. The results showed that in the range of 2.16í10-5-6.47í10-5 mg·mL-1, the total saponins had good linear relation-ship. The average recycle rate was 98.81%. RSD was 2.06%(n=6). It was concluded that the method was accurate, reliable and repeatable, which was suitable for determining the content of total saponins in JBYYX tablet.
ABSTRACT
This study was aimed to optimize the extraction process of ginseng in Shen-Qi Bu-Qi (SQBQ) granules. The orthogonal experiment method was used to optimize the extraction process of ginseng adopting ethanol concentration, ethanol volume, extraction time and extraction times as factors. The content of ginsenoside Rg1, Re, Rb1 content in the extract was determined by HPLC. And the optimum extraction conditions were determined with indexes of three kinds of saponin yield. The results showed that the optimum extraction process of ginseng for SQBZ granules was that adding 6 times amount of 60% ethanol technology for medicinal materials, extract for 2 times, and 3 h for each time. It was concluded that the optimization of ginseng extraction process was stable, reasonable and feasible with high extraction rate.
