Function:
Pterostilbene is a stilbenoid chemically related to resveratrol and is found in blueberries and grapes. It belongs to the group of phytoalexins, agents produced by plants to fight infections. Based on animal studies it is thought to exhibit anti-cancer, anti-hypercholesterolemia, anti-hypertriglyceridemia properties, as well as fight off and reverse cognitive decline.
Pterostilbene antioxidant: Pterostilbene is similar to the antioxidant resveratrol found in grapes and red wine, which also has anticancer activity. Pterostilbene is also present in grapes, but it is more abundant in blueberries. In the test tube and in animals that pterostilbene is capable of lowering cholesterol levels. If you would like to purchase a Resveratrol supplement.
Pterostilbene and colon cancer: A natural antioxidant abundant in blueberries called pterostilbene may help prevent colon cancer. Pterostilbene also suppressed the growth of cells in the colon and inhibited certain genes involved in inflammation, both of which are considered risk factors for colon cancer.
Laboratory animal model studies have provided evidence that stilbenes, phenolic compounds present in grapes and blueberries, play a role in inhibiting the risk of certain cancers. Pterostilbene, a naturally occurring stilbene from blueberries, was tested for its preventive activity against colon carcinogenesis. The results of the study suggest that pterostilbene, a compound present in blueberries, is of great interest for the prevention of colon cancer.
Pterostilbene as antioxidant: The antioxidant effect of pterostilbene on streptozotocin-nicotinamide-induced diabetic rats has been assessed. The activity of superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase and reduced glutathione was significantly decreased in liver and kidney of diabetic animals when compared with normal control. There were significant improvements in these activities after treatment with pterostilbene at a dose of 40 mg kg(-1) for six weeks. The increased levels of lipid peroxidation measured as thiobarbituric acid reactive substances (TBARS) in liver and kidney of diabetic rats were also normalized by treatment with pterostilbene. Chronic treatment of pterostilbene remarkably reduced the pathological changes observed in liver and kidney of diabetic rats. These results indicated the antioxidant property of pterostilbene.
