Abstract
IN a survey of the anthocyanin flower pigments of plants growing in Trinidad1, it was found that Lochnera (Vinca) rosea (Apocynaceae) contained an anthocyanin the aglycone of which was not identified. The fresh petals gave on chromatography a major glycosidic component of R F 0.29 together with traces of two others R F 0.23, 0.18 in the n-butanol/acetic acid/water (40 : 10 : 50) solvent used.
