The extracts were analysed by reversed\u2010phase high\u2010performance liquid chromatography. Mixture design gave an optimum solvent composition for extracting components from the plants of 36% dichloromethane, 17% ethanol and 47% ethyl acetate (by volume), while an optimum mobile phase for chromatographic analyses was found to be 27% methanol, 27% acetonitrile and 46% of water (by volume). Results from principal component analysis, hierarchical analysis and soft independent modelling by class analogy showed that\n                    <jats:italic>Bauhinia candicans<\/jats:italic>\n                    cannot be synonymous with\n                    <jats:italic>B. forficata<\/jats:italic>\n                    Link. It was also possible to trace the metabolic profile without identifying its chemical constituents and to determine a chromatographic discriminating region.
