[Studies on the chemical constituents from Aralia elata].
Eight compounds have been isolated from the root bark of Aralia elata. Their structures have been identified by means of physico-chemical and spectral analysis. They are (6'-O-palmitoyl)-beta-sitosterol-3-O-beta-D-glucoside (A5), silphiosideA (A9), chikusetusaponin Ib (A11), araloside A (A12), araloside C (A15), acanthoside D (B1). Compound A10 is a new natural product, named as araloside A methyl-ester. 3-O-beta-D-glucopyranosyl (1----3)[beta-D-glucopyranosy (1----4)]-beta-D-glucopyranosyl-oleanolic acid-28-O-beta-D-glucopyranoside (A16) is a new compound, named as araloside G. Compounds A5, A9, A10, A11, A16, and B1 were isolated for the first time from the plant. 13C-NMR chemical shifts of compounds A9 and A15 were assigned for the first time.
