Alkaline hydrolysis of the crude resin glycoside fraction of the leaves, stems, and roots of Calystegia soldanella ROEM. et SCHULT. (Convolvulaceae) gave four new glycosidic acids, named calysolic acids A, B, C, and D, along with one known glycosidic acid, soldanellic acid B, and three organic acids, 2S-methylbutyric, tiglic, and 2S,3S-nilic acids. The structures of the new glycosidic acids were characterized on the basis of spectroscopic data and chemical evidence.
对旋花科植物滨海旋花（Calystegia soldanella ROEM. et SCHULT.）叶、茎和根的粗树脂糖苷部分进行碱性水解，得到了四种新的糖苷酸，命名为滨海旋花酸A、B、C和D，以及一种已知的糖苷酸，滨海旋花酸B，还有三种有机酸，2S-甲基丁酸、惕各酸和2S,3S-尼罗酸。通过光谱数据和化学证据对新糖苷酸的结构进行了表征。
