| 以人参次苷Rh2为对照，分别对人参次苷H及其制剂进行指纹图谱研究，通过色谱条件的优化、方法的稳定性、精密度和重复性的研究，建立了人参次苷H与制剂的指纹图谱的色谱条件：用十八烷基硅烷键合硅胶为填充剂（优选Discovery C18 色谱柱）；乙腈-水（含0.1%的磷酸）为流动相,洗脱梯度：0～15min，40～55% 乙腈/水；15～55min，55～85% 乙腈/水；55～60min，85% 乙腈/水；检测波长203nm；柱温40℃。建立了人参次苷H及其制剂的指纹图谱，实验结果表明，本论文建立的指纹图谱检测方法具有良好的稳定性和可靠性，能较好的反映中间体与制剂中活性成分的相关性，可用于对人参次苷H 及其制剂的质量进行控制。 |

| 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 ℃. 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 |
