RESUMO
Objective To identify the scientific research status of Ershiwuwei-Shanhu pill among the literature review. Methods The literature were retrieved from CNKI, Wanfang and VIP databases (from databases built up to 2017), and quantitative analysis was carried out in the fields of time, journals and types of literature published. Results There were 58 literatures, including 33 clinical studies, 9 pharmacological studies, 14 pharmacological studies and 2 reviews. The literature published 39 kinds of journals, among which there were 81.0％ studies published in the journals holding the impact factors more and equal to 0.15 and 7 were core journals. Conclusions The results showed that the Ershiwuwei-Shanhu pill was in the developing period, mainly focused on clinical research, although there are some studies on pharmacology and pharmacy.The study of the ancient Tibetan medicine to the mature period there is still much space for development.
RESUMO
Objective This paper is intended for establishing quality standard of Ershiwuwei Shanhu pill. Methods The TLC was used to indentify Pyrethrum tatsienense, Sesami nigrum semen, Aquilariae lignum resinatum, Caryophmlli flos, Acori calami rhizoma, Chebulae fructus, Aucklandiae radix and Glycyrrhizae radix et rhizome. For hydroxysafflor yellow A, the HPLC system consisted of WondaSil-C18 (250 mm×4.6 mm, 5μm), methanol-acetonitrile- 0.7% phosphoric acid (26:2:72) as mobile phase, flow rate of 1.0 ml/min, detection wavelength at 403 nm. For liquiritin, the HPLC system consisted of WondaSil-C18 (250 mm×4.6 mm, 5μm), acetonitrile (A)-0.05% phosphoric acid (B) as mobile phase, flow rate of 1.0 ml/min, detection wavelength at 237 nm. And for crocin-I, the HPLC system consisted of WondaSil-C18 (250 mm×4.6 mm, 5μm), methanol-water (49:51) as mobile phase, flow rate of 1.0 ml/min, detection wavelength at 440 nm. Results The methods of TLC were simple with strong specificity and good reproducibility. The results of HPLC showed that calibration curve was linear in the ranges of 0.046 7-0.233 8μg for hydroxysafflor yellow A, and 0.510 6-1.531 8μg for liquiritin and 0.048 1-0.340 5μg for crocin-I. The average recovery rate was 102.01%, 99.50%and 99.32%, respectively. Conclusion The new method is more appropriate for the quality control of Ershiwuwei Shanhu pill.
