Four New Dicaffeoylspermidine Derivatives From Lycium barbarum

Abstract

Four new dicaffeoylspermidine derivatives, lycibarbarspermidines P–S (1–4), were isolated from the fruit of Lycium barbarum (wolfberry). The structures were determined by extensive spectroscopic (HRESIMS, 1D NMR, and 2D NMR) analyses and chemical methods. Dicaffeoylspermidine derivatives are a kind of major bioactive and characteristic constituents in wolfberry, and the discovery of 1–4 added new members of this family.
