AIM: To establish a HPLC method for the determination of tanshinone Ⅱ A in Compound Danguifukang Capsule. METHODS: Analytic column: Reliasil C18(5μm, 250mm×4.6mm), protective column: (5μm, 12.50mm×4.6mm); mobile phase: methnaol-ultrapure water (80: 20); detective wavelength was at 270a good linearity within the range of 1×10-2-0.16μg, r=0.9995. The average recovery was 99.73% and RSD was 2.91%. CONCLUSION: The method is feasible, and simple to operate and suitable for the quality control of Compound Dangguifukang Capsule.

AIM: To establish a HPLC method for the determination of tanshinone ⅡA in Compound Danguifukang Capsule. METHODS: Analytic column: Reliasil C 18 (5 ?m, 250 mm?4.6 mm), protective column:(5 ?m, 12.50 mm?4.6 mm); mobile phase: methnaol-ultrapure water (80∶20); detective wavelength was at 270 nm; temperature was at 30 ?C ; the flow rate was about 1.0 mL?min -1 . RESULTS: The standard curve showed a good linearity within the range of 1?10 -2 -0.16 ?g, r=0.999 5. The average recovery was 99.73% and RSD was 2.91% . CONCLUSION: The method is feasible, and simple to operate and suitable for the quality control of Compound Dangguifukang Capsule.
