摘要
A new RP-HPLC method for the determination of lead in Rhodiola species was established on a Shim-pack Vp-ODS column（150 mm×4.6 mm I.D.,5μm） at UV 255 nm.The column temperature is 300C.Bis（Salicyladehyde）o-phenydnediiminato was used as a on line derivate agent and MeOH-H2O-derivate agent（65:33.5:1.5,v/v） was made use of mobile phase.The method was applied for the determination of lead and the lineal range of lead is 0.1352-0.6759ng（r=0.9989）.The average recovery is 99.2% with RSD being 2.9%（n=5）.

Bis（Salicyladehyde）o - phenydnediiminato was used as a on line derivate agent and MeOH - H2O - derivate agent （65 ： 33.5 ： 1. 5, v/v ） was made use of mobile phase. The method was applied for the determination of lead and the lineal range of lead is 0.1352 - 0. 6759ng （ r =-0.9989 ）. The average recovery is 99.2% with RSD being 2.9% （ n = 5）.
