ABSTRACT
Objective To optimize the preparation technology of ?-cyclodextrin inclusion complex of Oleum Viticis Negundo.Methods Orthogonal test was applied.With the inclusion rate and the content of 1,8-Cineole as the parame ters,L9(34) table was used to examine the effects of 4 factors:the proportion of Oleum Viticis Negundo and ?-cyclodextrin,inclusion temperature,inclusion time and the proportion of Oleum Viticis Negundo and water.Results The best condition was∶oil ∶ ?-cyclodextrin∶ water=1∶8∶70(ml∶g∶ml),stirring for 1.5 hour at 50 ℃.Conclusion Under the optimized condition,inclusion rate of Oleum Viticis Negundo is over 80%.
ABSTRACT
Radix Ginseng and Rhizoma Chuanxiong were identified and the content of ginsenoside Rg_1 was determined by TCL scanning. The results showed that the content of ginsenoside Rg_1 ranged between 0.01770％ and 0.01826％, the recovery rate of ginsenoside Rg_1 was 99.94％ and the coefficient of variation derived from samples was 1.659％. This method is found to be stable, accurate and reliable.
ABSTRACT
The effect of Wei Yao on three kinds of experimental gastric ulcer rat models was reported. It was found that the drug can decrease the ulcer index and reduce the severity of gastric ulcer, and possesses an analgesic effect. The long-term toxicity test of Wei Yao showed that the drug was safe and nontoxic.
ABSTRACT
Objective: To establish the checking method for ginsenoside Rg 1 content in Radix Notoginseng and Qianliexiankang Capsules. Methods: Radix Notoginseng, Fructus Psoraleae and Fructus Forsythlae in Qianliexiankang Capsule were identified by TLC. The ginsenoside Rg 1 content in Qianliexiankang Capsules was determined by HPLC on HP Eclipse XDB C 18 column (4.6mm?150mm,3.5?m); using methanol water (55∶45) as a mobile phase; flow rate at 0.4ml/min; detection wavelength at 205nm. Results: The average recovery is 97.12% and RSD is 0.9% (n=5).Conclusion: The method is simple, sensitive, accurate and reproducible.
