| Abstract: | Objective] To make the use of high performance liquid chromatographic method(HPLC) to determine the content of active ingredient adenosine in RHIZOMA ET RADIX BAPHICACANTHIS CUSIAE from different production places in Guangdong Province.Method] A HPLC method was established for determining the content of adenosine.To be specific,HPLC analysis was performed on a chromatographic column ZORBAXExtend-C18(4.6 mm×250 mm,5 μm) with methanol-water(V/V,7∶93)as the mobile phase,detection wavelength at 260 nm,flow rate at 1.0 ml/min and column temperature at 30 ℃.Result] Adenosine had good linear relationship between concentration and peak area from 4.65 to 232.6 ng,the recovery rate was 100.3%,RSD=2.2%(n=6);the sample from Conghua in Guangdong Province had the highest content,while the two wild species had the lowest of that.Conclusion] The method is simple,accurate,rapid and reproducible.It can complete the existing quality standard of RHIZOMA ET RADIX BAPHICACANTHIS CUSIAE compound feed additives,and make the control of quality efficiently. |
