Studies on Checking Method for Radix Notoginseng and Qianliexiankang Capsules / 中成药

ABSTRACT

Objective: To establish the checking method for ginsenoside Rg 1 content in Radix Notoginseng and Qianliexiankang Capsules. Methods: Radix Notoginseng, Fructus Psoraleae and Fructus Forsythlae in Qianliexiankang Capsule were identified by TLC. The ginsenoside Rg 1 content in Qianliexiankang Capsules was determined by HPLC on HP Eclipse XDB C 18 column (4.6mm?150mm,3.5?m); using methanol water (55∶45) as a mobile phase; flow rate at 0.4ml/min; detection wavelength at 205nm. Results: The average recovery is 97.12% and RSD is 0.9% (n=5).Conclusion: The method is simple, sensitive, accurate and reproducible.
