title: A new cerebroside from Uvaria tonkinensis var. subglabra.
abstract: A new cerebroside, subglain A (1), together with five known compounds (2-6) have been isolated from the stems of Uvaria tonkinensis var. subglabra. The structure of 1 has been determined to be 1-O-beta-D-glucopyranosyl-(2S,3S,4R,8Z,2'R)-2-[N-(2'-hydroxytetracosanyl)-N-(1'',2''-dihydroxyethyl)-amide]-8-tetradecene-1,3,4-triol by spectroscopic evidence. The known compounds were identified as schisandriside (2), erythritol (3), beta-D-glucopyranose (4), kaempferol-3,7-O-alpha-L-dirhamnoside (5), and (+)-lyoniresinol (6).
