小青龙颗粒中麻黄碱的胶束薄层扫描测定

DETERMINATION OF EPHEDRINE IN XIAO QING LONG GRANULES BY MTLC SCANNING

以３．５％ＳＤＳ－０．１ｍｏｌ／Ｌ酒石酸－甲醇（１∶３）作流动相，硅胶Ｇ－ＣＭＣ－Ｎａ板作固定相，采用胶束薄层扫描法测定小青龙冲剂中麻黄碱的含量。在λＳ＝５２８ｎｍ测定平均回收率为９９．８４％，ＲＳＤ为１．３９％。

Ephedrine in Xiao Qing Long granules was determined using micellar thin layer chromatography(MTLC) scanning. The colloidal silica G CMC Na plate was used, with 3.5% SDS 0.1mol/L tartaric acid methanol(1∶3) as mobile phase, 528 nm as detection wavelength, and 630 nm as reference wavelength. The average recovery of ephedrine was 99.84%, RSD was 1.39%.
