Abstract: | Methanolic extracts from aerial parts and capsules of plants of 5 populations ofBlackstonia perfoliata and 99 populations of nine European and two AmericanCentaurium species (Gentianaceae) have been screened by means of TLC for the secoiridoid glucosides: sweroside, swertiamarin, gentiopicroside and the m-hydroxybenzoyl esters of sweroside, namely centapicrin, desacetylcentapicrin, decentapicrin A and B as well as for the xanthones: 1,8-dihydroxy-3,5-dimethoxyxanthone, 1,8-dihydroxy-3,7-dimethoxyxanthone, 1,8-dihydroxy-3,5,6,7-tetramethoxyxanthone and xanthone- -mono-glucosides. The taxonomical significance of the results is discussed. On the basis of chemotaxonomical evidence twoCentaurium species,C. pulchellum andC. tenuiflorum, are placed in sect.Parviflora instead of sect.Centaurium subsect.Parviflora.
