摘要：目的:建立一种以碳纳米管糊电极为工作电极的丹酚酸B的伏安测定方法,为丹酚酸B的分离过程进行质量监测。方法:在pH1.81的Britton-Robinson缓冲溶液中采用方波溶出伏安法对其进行测定。结果:建立的方法对丹参药材水提液经SP-207树脂柱分离洗脱过程中丹酚酸B的含量进行测定,所得结果与HPLC法测定的结果一致。结论:本方法为丹酚酸B的测定提供了新方法,为将来丹参的提取过程中丹酚酸B含量的变化在线质量控制提供了有利依据。
AIM ： A voltammetric method was developed for the determination of salvianolic acid B using a carbon nanotube paste electrode. And the separation process of salvianolic acid B was detected. METHODS： In Britton-Robinson buffer solution of pH 1.81, the square wave stripping voltammetric method was used to determine salvianolic acid B. RESULTS： The proposed method was verified by an established HPLC method, and it was applied to determining salvianolic acid B in eluent of eluting extracts of Radix salvia Miltiorrhiza from SP-207 colunm with ethanol solution, and the results were satisfied. CONCLUSION： A new method for determining salvianolic acid B was developed, and the proposed method would be used as an on-line quality control method for detecting of salvianolic acid B in eluting extracts of Radix salvia Miltiorrhiza in the future.
