Article Synopsis
- Resin glycosides, found in convolvulaceous plants, are known for their purgative properties and Calystegia hederacea, a widespread vine in India and East Asia, is used medicinally for various conditions.
- Alkaline hydrolysis of its crude resin glycoside fraction produced four new glycosidic acids (calyhedic acids A, B, C, and D) and other known acids, with their structures characterized through spectroscopic methods.
- Cytotoxic activity tests revealed that the crude resin glycoside fraction and certain macrolactone-type resin glycosides showed significant effects against human leukemia cells, while other variants exhibited weaker or no activity, highlighting the importance of structure in their effectiveness.
