Alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction of the seeds of Quamoclit pennata BOJER (Convolvulaceae) provided five new glycosidic acids, quamoclinic acids B, C, D, E, and F, along with six organic acids, isobutyric, 2S-methylbutyric, tiglic, 2R,3R-nilic, 7S-hydroxydecanoic, and 7S-hydroxydodecanoic acids. These new compounds were characterized on the basis of spectroscopic data as well as chemical evidence. Quamoclinic acids E and F are the first examples of heptaglycosides of glycosidic acid.
对 Quamoclit pennata BOJER(旋花科)种子的醚不溶性树脂苷(convolvulin)部分的碱性水解提供了五种新的苷酸、以及六种有机酸:异丁酸、2S-甲基丁酸、tiglic 酸、2R,3R-nilic 酸、7S-羟基癸酸和 7S-hydroxydodecanoic 酸。这些新化合物的特征是基于光谱数据和化学证据。Quamoclinic 酸 E 和 F 是苷酸七糖苷的第一个例子。
