Abstract:
A simple hollow fiber based centrifuge ultrafiltration pretreatment procedure has been developed for the analysis of active components with high polarity in Chinese traditional and herbal drugs which usually contain macromolecule impurities. The procedure combined with HPLC was applied to the determination of hesperidin in Huoxiangzhengqi water. Sample solutions were purified by our patent hollow fiber centrifuge ultrafiltration device. Under the effect of the centrifgual force, micromolecules were removed from solution samples, thus it increased the service life of the column. The accuracy and repeatability of this method have also been improved. The separation was carried out on a Promosil C18 column (4.6 mm x 150 mm, 5 microm) with methanol -0.5% acetic acid solution (35:65) as mobile phase at a flow rate of 1.0 mL x min(-1). The detector wavelength was 283 nm and the column temperature was 30 degrees C. A good linear relation was obtained in the range of 4.69 - 150 mg x L(-1) (r = 0.999 7) and the average recovery was 103.0% with RSD of 1.9%. This method is simple, rapid and accurate, and it provides a simple and cheap ultrafiltration means for the analysis of the polar components in Chinese traditional and herbal drugs.
