Two new alpha-pyrones and other components from the cladodes of Opuntia dillenii.
The aqueous ethanolic extract from the fresh cladodes of Opuntia dillenii HAW. was found to show anti-inflammatory activity. Two new alpha-pyrones, named opuntioside II (1) and opuntioside III (2), were isolated from the extract together with six known compounds. The structures of the new compounds were determined on the basis of chemical and physicochemical evidence.
