Abstract

Suspension cultures of Vitis vinifera L. (Vitaceae) produce many hydroxylated stilbene glucosides found in red wine. From these cells, we isolated and characterized glycosylated stilbenes, (Z)-piceatannol (3,5,3',4'-tetrahydroxystilbene) -3-O-beta-d-glucopyranoside (6) and (E)- and (Z)-resveratrol (3,5, 4'-trihydroxystilbene)-4'-O-beta-d-glucopyranoside (2 and 7, respectively), which have not previously reported to be constituents of Vitis vinifera or wine. The ability of these compounds to act as radical scavengers was investigated using 1,1 diphenyl-2-picryl-hydrazyl, a stable free radical. Antioxidant activities were assessed by their capacity to prevent Cu2+-induced lipid peroxidation in human low-density lipoprotein.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
