Abstract:
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)-
β-sitostero1-3-O-
β-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-
β-D-glucopyranosyl (1→3)
β-D-glucopyranosy (1→4)-
β-D-glucopyranosyl-oleanolic acid-28-O-
β-D-glucopyranoside (A
16) is a new compound, named as aralo-side G. Compounds A
5, A
9, A
10, A
11 A
16, and B
1 were isolated for the first time from theplant.
13C-NMR chemical shifts of compounds A
9 and A
15 were assigned for the first time.
