Soy Isoflavone Aglycones Are Absorbed Faster and in Higher Amounts than Their Glucosides in Humans
Toru Izumi,Mariusz K. Piskula,Sachiko Osawa,Akio Obata,Koichiro Tobe,Makoto Saito,Shigehiro Kataoka,Yoshiro Kubota,Mamoru Kikuchi +8 more
TL;DR: The isoflavone aglycones were absorbed faster and in greater amounts than their glucosides in humans and may be more effective than glucoside-rich products in preventing chronic disease such as coronary heart disease.
Journal ArticleDOI
Proanthocyanidin-rich extract from grape seeds attenuates the development of aortic atherosclerosis in cholesterol-fed rabbits
TL;DR: Results suggested that proanthocyanidins, the major polyphenols in red wine, might trap reactive oxygen species in aqueous series such as plasma and interstitial fluid of the arterial wall, thereby inhibiting oxidation of LDL and showing an antiatherosclerotic activity.
Journal ArticleDOI
Antiulcer Activity of Grape Seed Extract and Procyanidins
TL;DR: In this paper, the antiulcer activity of grape seed extracts (GSE-I and GSE-II) and procyanidin oligomers was investigated using rats.
Journal ArticleDOI
Safety evaluation of proanthocyanidin-rich extract from grape seeds
TL;DR: In this paper, the grape seed extract (GSE) was examined for acute and sub-chronic oral toxicity using Fischer 344 rats and for mutagenic potential by the reverse mutation test using Salmonella typhimurium, the chromosomal aberration test using CHL cells, and the micronucleus test using ddY mice.

Isoflavone Aglycone–Rich Extract without Soy Protein Attenuates Atherosclerosis Development in Cholesterol-Fed Rabbits
Jun Yamakoshi,Mariusz K. Piskula,Toru Izumi,Koichiro Tobe,Makoto Saito,Shigehiro Kataoka,Akio Obata,Mamoru Kikuchi +7 more
TL;DR: It is suggested that the antioxidative action of isoflavones and their antioxidative metabolites inhibit the oxidation of LDL, thereby exerting an antiatherosclerotic effect.
