RESUMO
OBJECTIVE:To establish an RP-HPLC method for simultaneous determination of Berberin hydrochloride,Baicalin and Glibenclamide in Kangtang tablets.METHODS:Separation of samples was achieved on a Diamond C18 analytical column(250 mm?4.6 mm,5 ?m).The mobile phase consisted of methanol-0.3% H3PO4(containing 0.3% triethylamine,pH2.5)using gradient program at a flow rate of 1.0 mL?min-1 and a detection wavelength of 230 nm.RESULTS:The linear ranges of Berberin hydrochloride,Baicalin and Glibenclamide were 0.02～1.0 mg?mL-1,0.02～1.0 mg?mL-1,0.000 8～0.04 mg?mL-1,respectively.The average recoveries were 100.16%,99.32% and 97.23%,respectively.The RSD were 1.97%、1.77%、1.28%,respectively(n=6).CONCLUSION:The method is simple,sensitive with high recovery rates and it is suitable for the quality control of Kangtang tablets.
RESUMO
AIM:To study the effect of berberin hydrochloride(Ber)on the elevation of blood concentra- tion of Cyclosporin A(CsA)and liver and renal functions in renal transplanted recipients.METHODS:138 cases with renal transplantation in experimental group were treated with CsA and Ber and 150 cases with renal trans- plantation in control group received CsA only.Blood lev- els of CsA,biochemistry indexes for liver and renal func- tion were determined.RESULTS:After 1,3,6 months combined with Ber,blood concentrations of CsA in pa- tients went up by 49.8%,81.4%,36.9% and the radios of blood concentration of CsA to CsA dosage increased 88.8%,102.0%,72.5% compared with those before taking Ber(P
