ABSTRACT
Objective: To establish a method for determinating icarin content in Naoling Granule. Methods: Water-soluble ethyl-acetate-extracting polyamide column purification was adopted. The content of icarin was determined by HPLC. C18 column was used, mobile phase was methanol:0.1mol/mL sodium phosphate dibasic (6:5) and detection wavelength was at 270nm. Results: Icarin has a good linearity in the range of 0.24～1.2?g ( r=0.9998). The average recovery was 98.23 %and RSD was 1.2 %(N=5). Conclusion: The method was simple with good reproducibility and can be used for the content determination of icarin in Naoling Granule.
ABSTRACT
Objective: To establish the quality standard for Guangxiao Liniao Capsules (Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae, etc.). Methods: Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae were identified by TLC, and the content of stachydrine hydrochloride was determined by TLC scanning. Results: Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae could be identified by TLC. Stachydrine hydrochloride showed a good linear relationship at a range of 4?g～20?g, r = 0.9975. The average recovery was 97.9%, and RSD was 1.20%. Conclusion: The methods are accurate and can be used for the quality control of Guangxiao Liniao Capsules
