Chromatographic and spectroscopic methods for the identification of alkaloids from herbarium samples of the genus Uncaria.

J D Phillipson, S R Hemingway.   

Abstract

A combination of thin-layer chromatography, gas-liquid chromatography, ultraviolet spectroscopy and mass spectrometry techniques for the alkaloid screening of herbarium samples of the genus Uncaria (Rubiaceae) is described. Some sixty alkaloids are distinguished by the screening procedure, and they represent heteroyohimbine, oxindole, roxburghine, simple beta-carboline, pyridino-indolo-quinolizidinone and gambirtannine types.
