Abstract:
Objective To develop an HPLC method for simultaneous determination of jasminoidin, baicalin, berberine hydrochloride and emodin in Zhizi Jinhua(ZZJH) Pills. Methods The analysis was performed on a Zorbax Eclipse XDB-C18(4.6 mm×150 mm, 5 µm) with gradient elution by using the mobile phase of acetonitrile-0.2% phosphoric acid solution. The column temperature was maintained at room temperature and the flow rate was 1.0 ml/min. The detection wavelengths were set at 240 nm and 275 nm, respectively. Results The calibration curves were linear within the range of 0.056-0.3360 µg (r=0.9998) for gardenoside, 0.2080.624 µg (r=0.9990) for baicalin, 0.116-0.696 µg (r=0.9994) for berberine hydrochloride, and 0.040-0.240 µg (r=0.9993) for emodin, respectively. The recoveries of gardenoside, baicalin, berberine hydrochloride and emodin were 91.18 %(RSD=1.60%)z 91.55%(RSD=0.75%)/91.19%(RSD=1.08%) and 92.29%(RSD=1.98%), respectively. Conclusion The method is convenient, fast, sensitive and reproducible, with good precision, specificity and accuracy. So it can be used for simultaneous determination of jasminoidin, baicalin, berberine hydrochloride and emodin in ZZJH Pills.
