Three phenolic glycosides were isolated together with two known flavonol glycosides from the H 2 O-soluble fraction of rhizomes of Kaempferia parviflora. Their structures were determined to be rel-(5aS,10bS)-5a,10b-dihydro-1,3,5a,9-tetrahydroxy-8-methoxy-6H-benz[b]indeno[1,2-d]furan-6-one 5a-O-[α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside] (1), its rel-5aS,10bR isomer (2), and (2R,3S,4S)-3-O-[α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranosyl]-3′-O-methyl-ent-epicatechin-(2α→O→3,4α→4)-(5aS,10bS)-5a,10b-dihydro-1,3,5a,9-tetrahydroxy-8-methoxy-6H-benz[b]indeno[1,2-d]furan-6-one 5a-O-[α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside] (3). The structures were elucidated on the basis of analyses of chemical and spectroscopic evidence.
