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.
ABSTRACT
AIM: To establish the determination of narigin and hesperidin in Juhong Pills(Exocarpium, Citri Grandis, Pericarpium Citri Reticulatae, Radix Angelicae Sinensis, etc.). METHODS: The extraction was completed with ether. The Shim-pack ODS(?6.0mm?150mm) column was used with mobile phase of CH 3OH-CH 3COOH-H 2O(30∶4∶60). The detection wavelength was at 283nm. RESULTS: The linear range for narigin was 0.072～1.43?g, r=0.9999 and the linear range for hesperidin was 0.068～1.37?g, r=0.9999, respectively. Both the average recoveries were 99.3% and 99.4%, respectively. Both RSD were 0.6%(n=5). CONCLUSION: The method is simple and the result is reliable.
