Two new chromanone acid derivatives,calophinophyllins A and В(1 and 2),together with a known one(3),were isolated from Calophyllum inophyllum.The structures of the new compounds were determined by NMR and HR-ESI-MS experiments,as well as by comparison of their data with the published values.All the isolated compounds were evaluated for their α-glucosidase inhibitory activity.None displayed measurable activity against a-glucosidase.
