[The determination of contents of 8 ginsenosides in extraction of Panax ginseng by HPLC].
OBJECTIVE
To establish a method to determine the contents of 8 ginsenosides in extraction of Panax ginseng by HPLC.


METHODS
The sample was analyzed on an ODS chromatogram column (Kromasil 250 mm x 4.6 mm, 5 microm), with mobile phase of acetonitrile-water (gradient elution) at flow rate 1.0 ml/min and detection at wavelength of 203 nm.


RESULTS
RSD of stability, precision and recurrency was 0.55%-2.26%, 0.85%-1.93% and 0.97%-2.72% respectively.


CONCLUSIONS
This method can be good for the content determination of ginsenoside.
