Three cerebrosides 2, 3, and 5 and two terpene glycosides 1 and 4 have been isolated from the methanol extract of the root of Asfer scaber. Their structures were determin ed as 3-0-β-D-glucuronopyranosyl-oleanolic acid methyl ester (1), (2S,3S,4R,2’R,8Z, 15’Z)-N-2’-hydroxy-15’-tetracosenoyl-1-0-β-D-glucopyranosyl- 4-hydroxy-8-sphingenine’(2), (2S, 3S, 4R, 8Z)-N-octadecanoyl-1-0-β-D- glucopyranosyl-4-hydroxy-8-sphingenine (3), 1α-hydroxy-6β-0-β-D-glucopyl-eudesm-3- ene (4), and (2S,3S,4R,2’R,8Z)-N-2’-hydroxy-hexadecanoyl-1-0-β-D- glucopyranosyl-4-hydroxy-8-sphingenine (5) on the basis of spectroscopic methods.
