| Abstract: | A new glycoside, ipopurpuroside, has been isolated from Ipomoea purpurea. The results of acid hydrolysis together with chemical and spectroscopic analyses have shown that it consists of glucose, rhamnose and 6-deoxy-D-glucose glycosidically linked to ricinoleic acid. The acyl group removed by alkaline hydrolysis was identified as methylbutyric acid. The carboxyl group of ipopurpuroside is esterified. |
