摘要	From the whole plant of Morina nepalensis var. alba Hand.-Mazz., two new acylated flavonoid glycosides (1 and 2), together with four known flavonoid glycosides (3-6), were isolated. Their structures were determined to be quercetin 3-O-[2"'-O-(E)-caffeoyl]-alpha-L-arabinopyranosyl-(1-->6)-beta-D-galactopyranoside (monepalin A, 1), quercetin 3-O-[2"'-O-(E)-caffeoyl]-alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranoside (monepalin B, 2), quercetin 3-O-alpha-L-arabinopyranosyl-(1-->6)-beta-D-galactopyranoside (rumarin, 3), quercetin 3-O-beta-D-galactopyranoside (4), quercetin 3-O-beta-D-glucopyranoside (5) and apigenin 4'-O-beta-D-glucopyranoside (6). Their structures were determined on the basis of chemical and spectroscopic evidence. Complete assignments of the H-1 and C-13 NMR spectra of all compounds were achieved from the 2D NMR spectra, including H-H COSY, HMQC, HMBC and 2D HMQC-TOCSY spectra.
