Abstract:
OBJECTIVE: To establish an HPLC method for the determination of 8-O-acetyl-shanzhiside methylester in Tibet medicinal Lamiophlomis rotata.METHODS: HPLC analysis was performed on Symmetry C18(150 mm?4.6 mm,5 ?m) column with the mixture of acetonitrile-water(15∶85) served as the mobile phase.The detection wavelength was set at 234 nm.RESULTS:The linear range of 8-O-acetyl-shanzhiside methylester was 1.97～19.68 ?g?mL-1(r=0.999 6) and its average recovery was 99.53%(RSD=1.73%,n=9).CONCLUSION: The method is simple,accurate and specific,and it applies reference for quality evaluation and utilization of Tibet medicinal L.rotata.
