Application of numerical methods in the investigation of the flavonoids of Christ, s thorn (Paliurus spina-christi Mill.)
The efficiency of ten thin-layer silica gel chromatographic systems for separating flavonoids is compared by using the information theory and numerical taxonomy. The design of the most effective series of chromatographic systems is discussed in terms of individual discriminating powers of the systems and the inter-system correlation. The most favourable chromatographical systems for the future quantitative analysis of the flavonoids from Paliurus spina-christi Mill. are: 1 (ethyl acetate:formic acid:acetic acid:water, 100:11:11:27), 2 (ethyl acetate:formic acid:water, 8:1:1) and 10 (chloroform:methanol:water, 6.5:3.5:1).
