RESUMEN
Objective@#Study on the improvement of quality standard for Zicao ointment.@*Methods@#The content of shikonin and β,β’-dimethylacrylshikonin was determined by high performance liquid chromatogram (HPLC). The column was Inertsil ODS-3 C18 column (4.6 mm×250 mm, 5 μm). The mobile phase comprising of acetonitrile-0.05% formic acid solution (70:30). The flow rate was 1.0 ml/min, the detection wavelength was 275 nm, and the column temperature was 25 ℃.@*Results@#The linear range of shikonin and β,β’-dimethylacrylshikonin were 0.04-0.81 μg (r=0.999 5) and 0.41-10.36 μg (r=0.999 2). The average recovery were 103.32% and 101.80%, the RSD were 1.96% and 2.11%.@*Conclusions@#The method is simple, accurate and sensitive to control the quality of Zicao ointment.
RESUMEN
Objective To establish the quality standards of Zizhu ointment. Methods The TLC was applied to identify Radix arnebiae and borneol of Zizhu ointment, and the content of borneol was determined by gas chromatography. Results The TLC spots were clear, well-separated and easy to identify. The good linear range of borneol reference substance on calibration curve was 0.048 4-1.210 0 μg, and the recovery was 90%-110%, the relative standard deviation was less than 5%. Conclusion The method is simple and feasible, can be used as the quality control method of Zizhu ointment.
RESUMEN
[Objective] To investigate the effect of external application of osmosis-improving herbal medicine and enema with blood-activating and stasis-removing herbal medicine for chronic pelvic inflammation. [Methods] Single-blind and randomized trial was performed on 120 cases of chronic pelvic inflammation. The cases were randomized to two groups: group A ( n = 57) was treated by enema with blood-activating and stasis-removing herbal medicine and group B ( n = 63) by the combination of enema and external application of osmosis-improving herbal medicine. Fourteen days constituted one course of treatment and the therapeutic effect was evaluated after two courses. [Results] In group A, 30 cases were cured, 21 effective, 6 ineffective and the total effective rate was 89.5%; 43 were cured, 18 effective, 2 ineffective and the total effective rate was 96.8% in group B. The result of Ridit analysis showed that the effect of group B was better than that of group A ( t = 3.08, P
RESUMEN
Objective To establish a method for the content determination of shikonin in Radix Arnebiae Oil by HPLC.Methods The content of shikonin was determined by HPLC and the chromatographic conditions were: Shim-pack VP-ODS column(4.6 mm?250 mm),the mobile phase consisting of methanol-0.025 mol/L H3PO4(85 ∶15),detection wavelength being 516 nm,tempeature at 25 ℃and the flow rate being 20 ?L.Results A good linearity of shikonin was in the range of 11.2 ?g/mL～33.6 ?g/mL(r=0.9998),and the average recovery rate was 101.03 %,RSD=1.91%.Conclusion This method was simple,accurate and with a good reproducibility and can be used for the quality control of Radix Amebiae Oil.
RESUMEN
AIM: To establish the HPLC fingprint spectrum of Radix Arnebiae as identification. METHODS: HPLC fingerprint spectrum of Radix Arnebiae collected from the seven production places and that of Radix Lithospermi from three production places were evaluated based on shikonin content. RESULTS: The major features of HPLC fingerprint of the seven production places were approximately similar to control sample there was no significant difference among the contents but Radix Lithospermi from three production places were not the same. CONCLUSION: The HPLC fingerprint spectrum of Radix Arnebiae can be used as an identification.It may provide the basis for quality control of Radix Arnebiae.
RESUMEN
Objective: To enhance the dissolution rate in vitro and bioavailability in vivo of the active components of extraction of Radix Arnebiae seu Lithospermi. Methods: Solid dispersion of extract of Radix Arnebiae seu Lithospermi were prepared with solid dispersion technology, X ray diffraction and stability experiments were also carried out. Results: The dissolution rates in vitro of the active components of extraction of Radix Arnebiae seu Lithospermi solid dispersion were obviously raised and stable, and the solid dispersion was not easy to age. Conclusion: The dissolution rate in vitro of the active components in Radix Arnebiae seu Lithospermi can be inproved greatly by the solid dispersion using PVP and HPMC as a carrier.
