Inhibition of Human Low-Density Lipoprotein Oxidation in Relation to Composition of Phenolic Antioxidants in Grapes (Vitis vinifera)
Abstract
Antioxidant activities of phenolic extracts from fourteen different types of fresh grapes were investigated by measuring the inhibition of human low-density lipoprotein (LDL) oxidation in vitro . The inhibition of LDL oxidation ranged from 22% to 60% at 10 μM gallic acid equivalents (GAE) of total phenols and from 62% to 91% at 20 μM GAE. The antioxidant activities were thus comparable to those previously found for wines. The relative LDL antioxidant activity correlated with the concentration of total phenols ( r = 0.89, p < 0.01), with the level of anthocyanins ( r = 0.56, p < 0.05) and flavonols ( r = 0.54, p < 0.05) in the grape extracts as analyzed by high-performance liquid chromatography (HPLC). When seed crushing and longer extraction times were employed, high amounts of flavan-3-ols and hydroxybenzoates were extracted. With these extracts relative LDL antioxidant activity correlated highly with the levels of flavan-3-ols ( r = 0.86, p < 0.01), total phenols ( r = 0.79, p < 0.05), and hydroxybenzoates ( r = 0.77, p < 0.05). Keywords: LDL oxidation; flavonoids; hydroxycinnamates; anthocyanins; flavan-3-ols; flavonols; HPLC

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.
