From the roots and upper parts of the Convolvulaceae IPOMOEA QUAMOCLIT, I. LACUNOSA, I. PANDURATA and CONVOLVULUS AL-SIRENSIS by ether-, petrolether and ethanol extraction respectively a resin material could be isolated, which yielded after alcaline hydrolysis glycosidic acids with jalapinolic acid as the common hydroxy fatty acid and the sugars rhamnose, glucose and xylose in different molar ratios.
