In contrast Rh2 for quercetin ginseng times respectively, the ginseng times glucoside H and preparation for research, through chromatographic fingerprint condition optimizing, method of stability, precision and repeatability of study to establish the ginseng times mangiferin fingerprint of H and preparation of chromatographic conditions: with 18 alkyl silane bonding silica gel for filling agent (optimization Discovery C18 column chromatography); Acetonitrile - water (including 0.1% of phosphoric acid) as mobile phase, 15min ses gradients: 0 ~, 40 ~ 55% acetonitrile/water, 15 ~ 55min, 55 ~ 85% acetonitrile/water, 60min, 55 ~ 85% acetonitrile/water, 203nm detected wavelength, Column temperature 40 ¡æ. Built ginseng times glucoside H and preparation of the fingerprint, the experimental results show that this paper establish fingerprint of detection method has good stability and reliability can better reflect intermediates and preparation of active ingredients of correlation
