| pubmed-article:2380300 | pubmed:abstractText | Octadecyl porous glass was used as the packing for reversed-phase high-performance liquid chromatography. A mixture of ginsenosides and saikosaponins (saponins of ginseng and bupleurum root, respectively) were analysed with detection at 203 nm. A well resolved chromatogram of ginsenoside Rb1, Rc, Rb2 and Rd and saikosaponin a, b2 and c was obtained with acetonitrile-water (25.5:74.5) as the mobile phase. The whole separation was achieved in 20 min with a flow-rate of 1.5 ml/min. Calibration graphs for ginsenoside Rb1, Rc, Rb2 and Rd and saikosaponin a and c were linear up to 5 micrograms. Rapid and accurate simultaneous determinations of the saponins are possible by the described method. | lld:pubmed |
