Glycosides from Stenochlaena palustris

A novel glycoside, (4S*,5R*)-4-[(9Z)-2,13-di-(O-beta-D-glucopyranosyl)-5,9, 10-trimethyl-8-oxo-9- tetradecene-5-yl]-3,3,5-trimethylcyclohexanone, namel y stenopaluside. and a new cerebroside, 1-O-beta-D-glucopyranosyl-(2S*, 3R* ,4E, 8Z)-2-N-[(2R)-hydroxytetracosanoyl]octadecasphinga-4,8-dienine, were i solated from the leaves of Stenochlaena palustris, along with four known na tural products, 3-oxo-4,5-dihydro-alpha-ionyl beta-D-glucopyranoside 3-form ylindole, lutein, and beta-sitosterol-3-O-beta-D-glucopyranoside. The struc tures of the isolates were elucidated by spectroscopic and chemical methods . (C) 1998 Elsevier Science Ltd. All rights reserved.
