Summary of "Phenylpropanoid glycosides from the fruit of Lycium barbarum L. and their bioactivity."

Fifteen phenylpropanoid glycosides, including six undescribed compounds were isolated from the fruit of Lycium barbarum L. (Solanaceae) (goji or wolfberry). Their structures were identified by detailed spectroscopic analyses. Seven known compounds were firstly isolated from the genus Lycium, in which the 1D and 2D NMR data of one compound were reported for the first time. Notably, two undescribed compounds were a pair of rare tautomeric glycoside anomers characterized by the presence of free anomeric hydroxy. Antioxidant and hypoglycemic activities of all these compounds were assessed using DPPH radical scavenging, oxygen radical absorbance capacity (ORAC), and α-glucosidase inhibitory assays, respectively. These compounds showed different levels of oxygen radical absorbance capacity, and some isolates exhibited potent antioxidant activity with greater ORAC values than the positive control (EGCG).

Medical and Biotech [MESH] Definitions

A plant genus of the family SCROPHULARIACEAE. Members contain phenylpropanoid glycosides and iridoids.

A plant genus of the family SCROPHULARIACEAE. Members contain phenylpropanoid and iridoid glycosides.

A plant genus of the family SMILACACEAE. Members contain smiglasides (phenylpropanoid glycosides) and steroidal saponins. Commercially it is sometimes adulterated with HEMIDESMUS, which would affect experimental results.

Glycosides from plants of the genus DIGITALIS. Some of these are useful as cardiotonic and anti-arrhythmia agents. Included also are semi-synthetic derivatives of the naturally occurring glycosides. The term has sometimes been used more broadly to include all CARDIAC GLYCOSIDES, but here is restricted to those related to Digitalis.

A plant genus of the family MYRTACEAE that bears an edible fruit and contains guavin B and quercetin glycosides.
