Danofloxacin was separated on a Hypersil BDS C 18 column. 色谱柱为 Hypersil BDS C1 8柱 ;

The analytes were extracted from plasma samples by liquid-liquid extraction, separated through a Hypersil BDS C18 column, and camptothecin was used as the internal standard. 血浆样品经液-液萃取后，以喜树碱为内标，采用Hypersil BDS C_(18)色谱柱进行分离。

Objective:To study on chromatography fingerprint(CFP) of Huangqi herbs.Method: HPLC was used on a Hypersil ODS column with water-acetonitriles gradient elution. 应用高效液相色谱法研究了黄芪的指纹图谱,并对毛蕊异黄酮、芒柄花素及黄芪甲苷进行了含量测定。

The column was hypersil BDS(4mm x 250mm). The mobile phase was 0. 1% triethylamine(adjusted to pH 3.2 with phosphoric acid)-acetonitrile(85:15). The detective wavelength was 256nm and the flow rate was 1ml/min. 色谱柱为Hypersil BDS(4mm×250mm)

DC, Method High-performance liquid chromatography (HPLC) was utilized for this purpose with the column of HYPERSIL BDS C18 and the mobile phase containing acetonitrile and water (50:50), the detection wavelength being 287 nm. 方法 采用高效液相色谱法（HPLC）,色谱柱为HYPERSIL BDS C18,流动相为乙腈:水（50:50）,检测波长287nm。

Method HPLC was adopted. The system consisted of Hypersil ODS2 column and methanol-0.1% phosphonic acid(23:77) as mobile phase with a flow rate of 1.0mL/min and the uV detection wavelength was 250 nm. 方法采用高效液相色谱法测定甘草酸的含量
