Studies on Rhubarb (Rhei Rhizoma). XV. : Simultaneous Determination of Phenolic Constituents by High-Performance Liquid Chromatography

抄録

Methods for simultaneous determination of phenolic constituents in rhubarbs have been established, making it possible to analyze almost all the phenolics, i.e., anthraquinones, anthrones, phenylbutanones, stilbenes, tannins, etc. Application of these methods to the evaluation of commercial rhubards has revealed that they can be classified into several groups on the basis of their chromatographic features.
