Galloyl, caffeoyl and hexahydroxydiphenoyl esters of dihydrochalcone glucosides from Balanophora tobiracola

Seven galloyl, caffeoyl and (S)-hexahydroxydiphenoyl esters of dihydrochalcone glucosides were isolated from Balanophora tobiracola. The 3-galloyl-4,6-HHDP esters strongly inhibited α-glucosidase.
