Dicliptercerebroside, a novel cerebroside from Dicliptera chinensis

Abstract

A novel cerebroside named dicliptercerebroside (1) was isolated from the whole herb of Dicliptera chinensis, together with two known compounds asperglaucide (2) and amidoalcohol (3) for the first time from the title plant. Their structures were elucidated using spectroscopic methods. The structure of dicliptercerebroside was determined as 1-O-β-d-glucopyranosyl-2N-[(2′R)-2′-hydroxy-(9Z)-palmitoleoyl]-2S,3S,4R-C₂₀-phytosphingosine.
