title: Cerebrosides and terpene glycosides from the root of Aster scaber.
abstract: Three cerebrosides 2, 3, and 5 and two terpene glycosides 1 and 4 have been isolated from the methanol extract of the root of Aster scaber. Their structures were determined as 3-O-beta-D-glucuronopyranosyl-oleanolic acid methyl ester (1), (2S, 3S, 4R, 2'R, 8Z, 15'Z)-N-2'-hydroxy-15'-tetracosenoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (2), (2S, 3S, 4R, 8Z)-N-octadecanoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (3), 1alpha-hydroxy-6beta-O-beta-D-glucosyl-eudesm-3-ene (4), and (2S, 3S, 4R, 2'R, 8Z)-N-2'-hydroxy-hexadecanoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (5) on the basis of spectroscopic methods.
