ABSTRACT
AIM:
To establish an HPLC method for determining geniposide and liquiritin in Zhizi Baipi Decoction(Fructus Gardeniae,Cortex Phellodendri Chinensis,Radix et Rhizoma Glycyrrhizae).METHODS:
A Kromasil C_(18) Column(4.6 mm?250 mm,5 ?m) was used.The mobile phase was methanol-0.5% glacial acetic acid for gradient elution.The flow rate was 1.0 mL/min,?_1=238 nm(detect the geniposide),?_2=276 nm(detect the liquiritin).The column temperature was at 30 ℃.RESULTS:
The linear range of geniposide was within 49.1 ?g/mL-147.4 ?g/mL,r=(0.999 8),the recovery was(99.40%)(n=9).The linear range of liquiritin was within 6.1 ?g/mL-18.4 ?g/mL,r=(0.999 9),the recovery was 99.94%(n=9).CONCLUSION:
This method has good reproducibility.It can be used for quality control in the production of Zhizi Baipi Decoction.
