Studies on the Iridoid Glycoside of the Plants of Genus Galium (Rubiaceae) Distribution of Asperuloside

Distribution of asperuloside and its related compounds in the aerial parts of 14 kinds of Genus Galium pants was examined using thin-layer chromatography. It was found that Asperuloside is present in all these plants and the presence of related compounds was observed in several plants. Asperuloside was isolated in crystalline form from all of the 14 tested plants.
