ABSTRACT
This study was aimed to screen out a safe and effective traditional Chinese medicine (TCM) compound prescription in insomnia treatment, through the method of uniform design and comprehensive scoring method. It provided candidate drugs to further research and development of TCM new drug. U7(76) uniform design was used to divide groups. The test was given on sleep time prolonging effect of mice injected with pentobarbital sodium. The subliminal dosage of pentobarbital hypnosis was tested on mice injected with pentobarbital sodium. The acute toxicity (LD50) was tested on mice. Comprehensive scoring method was applied to evaluate the effect to determine the optimum dose. The results showed the optimized prescription was composed of Radix Sophorae Flavescentis and Schisandra chinensis. The optimum ratio was 1:3. It was concluded that the uniform design was applied in the experimental design with 3 factors and 6 levels. Comprehensive scoring method was used to evaluate the combined effect. The optimized prescription that put benefit and risk into consideration was composed of Radix Sophorae Flavescentis and Schisandra chinensis. The best ratio was 1:3, which can be further developed.
ABSTRACT
This article reviewed occurrence of ADR of clinical external use of 50 Chinese medicinal herbs, such as Verbascum Thapsus, Ranunculus Sceleratus, and Euphorbia Esula. It summarized from foundation, property, efficacy, clinical manifestation, and classification of ADR, and discussed early warning ways of ADR from TCM external use, with a purpose to provide references for TCM reasonable medication.
ABSTRACT
Objective To study the preparation and quality standard of series of Shengmai Injection, and supply substantial basis and quality assurance for compatibility relation research on traditional Chinese medicine in vivo. Methods According to the preparing process of Shengmai Injection, preparing processes for 7 dismantlement injections were established. HPLC and TLC methods were used for qualitative analysis and quantitation determination of Ginsenoside Rg1, Ginsenoside Re, Ginsenoside Rb1, Schisandrin and Radix Ophiopgonis. Results The linear ranges of Ginsenoside Rg1 and Ginsenoside Re were 0.942 4～9.424 ?g (r=0.999 5) and 0.624～6.24 ?g (r=0.999 7). The average recovery was 97.0%～ 100.4%, and RSD was 0.45%～3.44%. The main spots of Ginsenoside Rg1, Ginsenoside Re, Ginsenoside Rb1, Schisandrin and Radix Ophiopgonis were identified by TLC method. Conclusion The preparation processes are stable. The method of quality control was showed rapid, reliable and well reproducible. It set a good basis for the compatibility study on Shengmai Injection in vivo.
ABSTRACT
Object To investigate the process of flocculation impurity removal for the Anti-flu Nose Drops (AND). Methods Five kind of effective factors on flocculation impurity removal with the index of clarifying results were studied. Comparative tests for Shandong Yaosheng 1 + 1 (Ⅲ) clarificant, 50% alcohol precipitation, and 75% alcohol precipitation were performed with the quantitative index of gardenoside contents, the qualitative index of magnolin and gardenoside TLC chromatograms. The optimum process condition was selected out. Results Under the optimum process condition of flocculation impurity removal, gardenoside contents in the flocculation group is higher than those in 50% , 75% alcohol groups. TLC chromatograms showed that the spots of flocculation group are the same as those in the original liquid group. Conclusion Shandong Yaosheng 1 + 1 (Ⅲ) clarificant has following advantages; high reserved rate of active components, simple operation, cheap cost, stable process, which is a ideal method for the impurity removal.
