Quality standards of Kangxian Pills / 中成药

ABSTRACT

AIM: To establish the methods of quality control of Kangxian Pills (Redix Astragali,Radix Angelicale Sinensis,Rhizoma Chuanxiong,Radix Scutellariae,Fructus Schisandrae Chinensis,etc.). METHODS: Radix Angelicae sinensis;Rhizoma Chuanxiong;Radix Astragali;Radix Scutellariae were identified with TLC and the content of deoxyschizandrin and schisandrin B in the Kangxian Pills were determined by HPLC The separation was performed on Diamonsil~(TM) C_(18)(4.6 mm?250 mm,5 ?m)analytical column with a mobile phase consisted of methanol and water(78(∶)22) at the flow rate of 1.0 mL/min.The UV detection wavelength was set at 254 nm first and was altered to 220 nm after 17 min. RESULTS: The same color spots in the TLC graphs of sample existed at the corresponding position compared with the reference solution.The linear range of deoxyschizandrin was within 0.39-(1.95) ?g(r=0.999 9).The average recovery was 98.8%,RSD was 1.7%.The linear range of schisandrin B was within 0.09-0.45 ?g(r=0.999 9).The average recorery was 99.1%,RSD was 1.7%. CONCLUSION: The methods are simple and have good reproducibility.
