A New Cerebroside from the Roots of Gynura procumbens

A new cerebroside (1), along with three known steroidal compounds, β-sitosterol (2), daucosterol (3), and stigmasterol (4), were isolated from the roots of Gynura procumbens (Lour.) Merr. The structure of 1 was determined to be 1-O-β-D-glucopyranosyl-(2R,6E,9R,12E)2-[(2′R)-2′-hydroxypentacosaneoyl-amino]-6,12-heptadecene-1,9-diol on the basis of chemical and spectroscopic...
