Application of gas-liquid chromatography for standardization of herbal raw materials and herbal drugs

Abstract

Gas chromatography with mass selective detection is described as method for investigation and standardization of herbal raw materials and herbal drugs. Marker compounds and chromatographic conditions are described for some herbs.Gas chromatography has come into the practice of separation, qualitative and quantitative analysis of drug raw materials, determination of active substances in manufactured drugs, and stability studies on drugs for establishing their expiry dates. Pharmaceutical analysis makes use of the gas−liquid, gas−adsorption, gas− adsorption−adsorption variants of gas chromatography.
