New long-chain hydroxyalkyl ferulates from the root bark of Lycium chinense Mill

J Asian Nat Prod Res. 2009 Jul;11(7):681-5. doi: 10.1080/10286020903002139.

Abstract

Two new long-chain hydroxyalkyl ferulates, (E)-22-hydroxydocosyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (lyciumol A, 1) and (E)-20-hydroxyeicosyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (lyciumol B, 2), together with eight known compounds, were isolated from the root bark of Lycium chinense Mill. Their structures were elucidated by spectroscopic methods, including 1D, 2D NMR, and HR-ESI-MS analysis.
