Abstract
A gas-liquid chromatographic (GLC) method has been developed for the separation and determination of dihydroergotoxine alkaloids (dihydroergocristine, dihydroergokryptine and dihydroergocornine), involving quantitative decomposition of the compounds catalysed by a metal surface. GLC was carried out with 2% Dexsil 300 on Gas-Chrom Q as stationary phase, with temperature programming. For the quantitation, phenylbutazone was used as the internal standard.
摘要
已开发出一种气液色谱（GLC）方法，用于分离和测定二氢麦角毒生物碱（二氢麦角克碱、二氢麦角隐亭和二氢麦角柯宁），该方法涉及金属表面催化的化合物定量分解。使用涂有2% Dexsil 300的Gas-Chrom Q作为固定相进行程序升温GLC。定量时，使用保泰松作为内标。
