To determine the contents of twelve ginsenosides in the root of Panax ginseng by HPLC.
The analysis is carried out at room temperature on a Luna NH2 column (4.6 mm x 150 mm, 5 microm) eluted with acetonitrile and water as the mobile phases in a gradient elution. The flow-rate was 1.0 mL x min(-1), the detection wavelength was 203 nm.
Twelve ginsenosides (Rh2, Rh1, Rg2, Rg3, Rg1, Rf, Re, Rd, Re, Rb2, Rb3, Rb1) were separated at baseline within 60 min with good linearity (r > or = 0.999 5). The recovery rates were 98.1%, 95.3%, 96.1%, 95.6%, 97.3%, 98.6%, 98.0%, 96.4%, 96.1%, 97.6%, 96.8%, 96.9% (RSD < or = 3.0%).
The method was simple,fast and could control the quality of P. ginseng effectively.
采用高效液相色谱法测定人参根中12种人参皂苷的含量。
在室温下，于Luna NH2柱（4.6 mm×150 mm，5μm）上进行分析，以乙腈和水为流动相进行梯度洗脱。流速为1.0 mL·min⁻¹，检测波长为203 nm。
12种人参皂苷（Rh2、Rh1、Rg2、Rg3、Rg1、Rf、Re、Rd、Rc、Rb2、Rb3、Rb1）在60分钟内实现基线分离，线性关系良好（r≥0.999 5）。回收率分别为98.1%、95.3%、96.1%、95.6%、97.3%、98.6%、98.0%、96.4%、96.1%、97.6%、96.8%、96.9%（相对标准偏差≤3.0%）。
该方法简便、快速，可有效控制人参的质量。
