Nat Prod Res. 2009;23(14):1330-6. doi: 10.1080/14786410902836677.

Abstract

A new cerebroside (1) was isolated from the aerial parts of Gynura divaricata DC., along with five known compounds: kaempferol (2), kaempferol 3-O-glucoside (3), kaempferol 3-O-rhamnosyl(1 --> 6)glucoside (4), beta-sitosteryl glucoside-6'-O-heptadecoicate (5) and 2-(1', 2', 3', 4'-tetrahydroxybutyl)-6-(2'', 3'', 4''-trihydroxybutyl)-pyrazine (6), which are isolated for the first time from this species. The structure of 1 was determined to be 1-O-beta-D-glucopyranosyl-(2S, 3S, 4R, 10Z)-2-[(2'R)-2'-hydroxylignocenoyl-amino]-10-octadecene-1,3,4-triol on the basis of chemical and spectroscopic evidence.
