Danofloxacin was separated on a Hypersil BDS C 18 column. 色譜柱為 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. 血漿樣品經(jīng)液-液萃取后，以喜樹(shù)堿為內(nèi)標(biāo)，采用Hypersil BDS C_(18)色譜柱進(jìn)行分離。

Objective:To study on chromatography fingerprint(CFP) of Huangqi herbs.Method: HPLC was used on a Hypersil ODS column with water-acetonitriles gradient elution. 應(yīng)用高效液相色譜法研究了黃芪的指紋圖譜,并對(duì)毛蕊異黃酮、芒柄花素及黃芪甲苷進(jìn)行了含量測(cè)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. 色譜柱為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 采用高效液相色譜法（HPLC）,色譜柱為HYPERSIL BDS C18,流動(dòng)相為乙腈:水（50:50）,檢測(cè)波長(zhǎng)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譜法測(cè)定甘草酸的含量
