fucopyranosyl, while the J value of H-1000 (7.8 Hz) indicated the
b-D-configuration of quinovopyranosyl. The structures of aquilar-
inenside B (2) and aquilarinenside C (3) were thus determined to be
iriflophenone 2-O-b-D-fucopyranosyl-(1 ! 4)-O-a-L-rhamnopyra-
noside and iriflophenone 2-O-b-D-quinovopyranosyl-(1 ! 4)-Oa-
L-rhamnopyranoside, respectively.
