| Abstract: | For acquiring the fingerprint of Chinese traditional medicine of American ginseng (Panax quinquefolium L.) by capillary electrophoresis, the parameters of the sample processes and separation of the ginseng (dry) extract (reflux by 70% ethanol solution) was optimized by variable dimension expansion-selection method, with uniform design method for arranging experiments. An electropherogram with good resolution could be obtained under the optimal conditions. The correlation coefficients between the area of main peaks and the mass of the ginseng were more than 0.930. |
