Synthesis of water soluble glycosides of pentacyclic dihydroxytriterpene carboxylic acids as inhibitors of α-glucosidase

- Chemical glycosylation strategy of maslinic acid and corosolic acid was performed.
- The water solubility of the derivatives was better than the parent compounds.
- The α-glucosidase inhibitory activities of the derivatives were evaluated in vitro.
- Corosolic acid bis-lactoside exhibited a better inhibitory activity than acarbose.
