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 (A-5), silphiosideA (A-9), chikusetusaponin I-b (A-11), araloside A (A-12), araloside C (A-15), acanthoside D (B-1). Compound A-10 is a new natural product, named as araloside A methyl-ester. 3-O-beta-D-glucopyranosyl (1 fwdarw 3) (beta-D-glucopyranosyl (1 fwdarw 4)) -beta-D-glucopyranosyl-oleanolic acid-28-O-beta-D-glucopyranoside (A-16) is a new compound, named as araloside G. Compounds A-5, A-9, A-10, A-11, A-16, and B-1 were isolated for the first time from the plant. 13C-NMR chemical shifts of compounds A-9 and A-15 were assigned for the first time.
