Abstract


ABSTRACT – HCTN7

Many species of the genus Aralia are used as the traditional medicine in Asia and America to treat lameness, rheumatic arthritis, nephritis, gastritis, lumbago, inflammation, and diabetes mellitus, but the vast majority of this genus has not been explored, such as Aralia hiepiana J.Wen & Lowry (Araliaceae), an endemic species of Lamdong province. Phytochemical investigation of the leaves of A. hiepiana has led to the isolation of 3-O-{[β-D-xylopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl} oleanolic acid 28-O-β-D-glucopyranosyl ester (1), 3-O-{[β-D-xylopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl} oleanolic acid 28-O-β-D-glucopyranosyl ester (2), methyl-α-L-rhamnopyranoside (3), and methyl-α-D-glucopyranoside (4) which were isolated for the first time from this plant. The structural determination was accomplished by spectroscopic analysis, particularly by 1D NMR, 2D NMR.
