Results indicate that the methanol extracts of CR and S exhibit anti-radical activity in vitro, as well as cancer preventive efficacy on colon cancer cells, with S having slightly higher activity. Both antioxidant and anti-inflammatory effects were dependent on the duration of exposure. A significant reduction in IL-8 levels and NF-kappaB p65 activation was also observed. Both products suppressed cell proliferation, while the levels of glutathione and cyclooxygenase 2 were significantly decreased. All extracts exhibited DPPH˙ scavenging activity in a dose-dependent manner. Antioxidant, anti-inflammatory and anti-proliferative effects on HT29 cell culture were evaluated. The total polyphenol content and anti-radical activity were measured by Folin-Ciocalteu and DPPH, respectively. Methanol extracts of CR and S were used at different concentrations. In the present study, we investigated the effects of CR and S on human colon cancer cells. Corinthian raisins (Currants, CR) and Sultanas (S) (Vitis vinifera L., Vitaceae) are dried vine fruits produced in Greece with many culinary uses in both the Mediterranean and the Western nutrition. Dietary patterns influence the risk of colon cancer development, while plant-derived foods have gained great interest, due to the high content of antioxidants.

Of course, we sell a fair selection of the above, if you are interested. They include:Ĭatalpa bignonoides (Indian Bean Tree, Foxglove Tree) So here is, fat free, the take away: Life finds a way, so there are a number of plants that don't mind juglone and can be planted near your black walnut. Incidentally, juglone is probably one of the reasons that black walnut is so resistant to Honey Fungus. If you have a black walnut and trees and shrubs relatively close to it suffer wilting, yellowing foliage and either die or stop growing, now you know why.
And black walnut specifically is the biggest natural producer of juglone, which it uses to great effect to kill unrelated plants and trees nearby. Juglans is the root for juglone which is an allelopathic drug. I "sort of knew something" about black walnut's ability to kill other plants but the students of Hadlow made it very clear. For the rest of us it might be a mystery unless you are lucky like me and happened to see an information leaflet on the stand of Hadlow College who were strutting their stuff at the Chelsea Flower Show. To chemists amongst you, the word Juglans should tell you all you need to know. When you sell as many plants as we do, this happens sometimes, and we replace them under guarantee, so all is not lost, dear customer! This is a question we often get from people who bought trees and shrubs from us that died when planted near Juglans nigra. "Could my black walnut trees have killed other plants nearby?"
