Two New Cerebrosides from the Aerial Parts of Tithonia diversifolia

Abstract

Two new cerebrosides, (2R)‐N‐{(1S,2S,3R,8E)‐1‐[(β‐D‐glucopyranosyloxy)methyl]‐2,3‐dihydroxyheptadec‐8‐en‐1‐yl}‐2‐hydroxyhexadecanamide (1) and (2R)‐N‐{(1S,2R,8E)‐1‐[(β‐D‐glucopyranosyloxy)methyl]‐2‐hydroxyheptadec‐8‐en‐1‐yl}‐2‐hydroxyhexadecanamide (2), were isolated from the aerial parts of Tithonia diversifolia (Hemsl.) A. Gray. Their structures were determined on the basis of spectroscopic analysis (IR, HR‐ESI‐MS, and 1D‐, and 2D‐NMR).
