Great interest is currently centred on the biologic activities of pycnogenol a standardized plant extract obtained from the bark of the French maritime pine Pinus pinaster (formerly known as Pinus maritima), Aiton, subspecies Atlantica des Villar (Pycnogenol, Horphag Research Ltd., UK, Geneve,

The effects of reactive nitrogen species on glutathione homeostasis in human endothelial ECV 304 cells challenged by 3-morpholinosydnonimine-N-ethylcarbamide (SIN-1) on RAW 264.7 activated macrophages using a co-culture model were investigated. SIN-1 or macrophages activated by lipopolysaccharide

The application of PAGE to determine the interaction between procyanidins and proteins, as presented here, enables one to directly determine the binding of either a pure of a complex mixture of flavonoids to a particular protein. If the protein of interest is an enzyme, the combination of PAGE with

Grape (Vitis vinifera) and pine (Pinus pinaster) bark extracts are widely used as nutritional supplements. Procyanidin-rich fractions from grape and pine bark extract showing different mean degrees of polymerization, percentage of galloylation (percentage of gallate esters) and reactive oxygen

Pycnogenol, an extract from French maritime pine bark (PBE), is a complex mixture of bioflavonoids with reported protective effects against disease. PBE is an effective scavenger of reactive oxygen species, and its main constituents are procyanidins of various chain lengths. To find out the

Pine (Pinus pinaster) bark is a rich source of procyanidin oligomers. From a total polyphenolic extract, we have generated fractions of different procyanidin composition. The mixtures, devoid of gallate esters, were active as free radical scavengers against ABTS(*+), DPPH, and HNTTM. Pine bark

Orally in liquid diet administered procyanidin-containing extracts from Pinus pinaster Ait. decreased the croton oil-induced ear edema in mice or the compound 48/80-induced hind paw edema in rats to a statistically significant extent. Most effective were the extracts containing mainly oligomeric

A procyanidin-rich extract from French maritime pine, Pycnogenol(R) (PYC), is known as an antioxidant that exerts a variety of physiological activities and is widely used in human beings. We report here that PYC inhibits not only human immunodeficiency virus type-1 (HIV-1) binding to host cells, but

Inflammation and oxidative stress are related to cancer initiation and progression. We hypothesized that dietary supplementation with a procyanidin-rich Pinus pinaster extract (Pyc) with known antioxidant and anti-inflammatory effects could induce systemic protection, thereby attenuating tumor

BACKGROUND Oligopinۚ (OP) is a quantified extract from French Maritime Pine bark (FMPB) with low molecular weight procyanidins. The cardioprotective effects of OP need to be tested in human clinical intervention trials with an appropriate design. OBJECTIVE The aim of the present study was to assess

The standardized maritime pine bark extract (Pycnogenol) was reported to exert clinical anti-diabetic effects after peroral intake. However, an increased insulin secretion was not observed after administration of the extract to patients. Our aim was to elucidate whether the described clinical

Pinus koraiensis Bark Procyanidins Extract (PKBPE) has been used in traditional Chinese medicine for thousands of years. In this study, we determined PKBPE effect on tumor weight, SOD (superoxidate dismutase) activity, the content of MDA (malondialdehyde) through colorimetric analysis antigenic, and

The skin penetrating antioxidant cysteamine derivative of (-)-epicatechin as well as other thio conjugates were efficiently obtained with high yields from pine (Pinus pinaster) bark by simultaneous one pot extraction and depolymerization using water and cysteamine hydrochloride. The influence of the

There is growing interest in the biologic activities of plant extracts such as that obtained from the bark of the French maritime pine Pinus maritima, Pycnogenol. Pycnogenol (PYC) is a standardized extract composed of a mixture of flavonoids, mainly procyandins and phenolic acids. Studies indicate
