摘要	Four new oleanane type saponins, monepalosides G-J ( 1 - 4 ), were isolated from the water-soluble part of the whole plant of Morina nepalensis var. alba Hand-Mazz. On the basis of chemical and spectroscopic evidence, their structures were determined as 3- O -alpha- l -arabinopyranosyl-(1-->3)-alpha- l -arabinopyranosyl oleanolic acid 28- O -beta- d -glucopyranosyl-(1-->6)-beta- d -glucopyranoside (monepaloside G, 1 ), 3- O -alpha- l -arabinopyranosyl-(1-->3)-beta- d -xylopyranosyl oleanolic acid 28- O -beta- d -glucopyranosyl-(1-->6)-beta- d -glucopyranoside (monepaloside H, 2 ), 3- O -alpha- l -arabinopyranosyl-(1-->3)-[beta- d -glucopyranosyl-(1-->2)]-alpha- l -arabinopyranosyl oleanolic acid 28- O -beta- d -glucopyranosyl-(1-->6)-beta- d -glucopyranoside (monepaloside I, 3 ), 3- O -beta- d -glucopyranosyl-(1-->4)-beta- d -glucopyranosy-(1-->3)]-alpha- l -arabinopyranosyl oleanolic acid 28- O -beta- d -glucopyranosyl-(1-->6)-beta- d -glucopyranoside (monepaloside J, 4 ), respectively. Two-dimensional NMR spectra, including H-H COSY, HMQC, 2D HMQC-TOCSY, HMBC and ROESY were utilized in the structure elucidation and complete assignments of H-1 and C-13 NMR spectra.
