Objective:To establish the determination method of Tanshinone ⅡA in Radix Et Rhizoma Salviae Miltiorrhizae microemulsion by HPLC.Methods:The analysis was performed on a Diamonsil-C18 column(4.6 mm×250 mm
5 μm)
with a mobile phase of methanol-water(80∶20).The flow rate was 1 mL·min-1.The detection wavelength was 270 nm.The column temperature was 35 ℃.Results: The calibration curve was linear in the range of(7.59~303.44)ng
r=(1.000 0).The accuracy
repeatability
stability and recovery of this method were satisfied.Conclusions:The established method of determinating for the content of Tanshinone ⅡA in Radix Et Rhizoma Salviae Miltiorrhizae microemulsion was convenient
