A Kaempferol-3-O-β-D-glucoside, Intervention Effect of Astragalin on Estradiol Metabolism
A recent study found that a flavonoid known as astragalin possesses a strong anti-tumor effect. High levels of a metabolite formed from the hormone estradiol have been found in tumor tissues leading researchers to search for an inhibitor to prevent estradiol from forming the metabolite. This study has found that astragalin, which is a naturally occurring substance found in a variety of plants and wine, has an effective antitumor mechanism that inhibits the formation of the metabolite.
Flavonoids in common and Tartary Buckwheat hull extracts and antioxidant activity of the extracts against lipids in mayonnaise
A recent study has revealed that the various flavonoids in buckwheat hulls are a reliable source for antioxidant material. When a buckwheat hull extract was made and exposed to mayonnaise, the shelf-life of the mayonnaise was extended, likely related to the antioxidant properties. This study was able to determine the effectiveness of extracts from the common and Tartary Buckwheat hulls, as well as provide an efficient extraction method.
Effect of citrus peel extracts on the cellular quiescence of prostate cancer cells
A recent study has revealed that citrus peel extracts (CPE) have the potential to prevent prostate cancer from recurring in post-therapy cancer patients. A component of CPE, flavonoids, have previously been found to have anticancer effects, but appear to lack the correct structure to prevent tumors in patients with prostate cancer. This specific study found that the citric acid present in CPE was the contributing factor to its anticancer effects but mentioned that flavonoids should continue to be researched for chemopreventive benefits.
A recent study has found that flavonoids isolated from Psoralea corylifolia are able to inhibit part of the insulin pathway.
Seeds of the P. corylifolia plant have been used in eastern medicine, primary in China, for years, and is now being further researched as flavonoids continue to intrigue researchers with their possible therapeutic benefits. The inhibitory activity found in this study provides evidence that flavonoids should be pursued as a potential treatment for Type-2 Diabetes.
Citrus peels waste as a source of value-added compounds- extraction and quantification of bioactive polyphenols
A recent study has exposed a more efficient, sustainable, and economically viable extraction method for polyphenols (specific active chemical compounds) from citrus peels. One such polyphenol is Naringin, a flavonoid present in lemon peels, which has been hypothesized to have anti-inflammatory and antioxidant effects, as well as, potentially, to help treat obesity. This new extraction method will allow researchers to discover more definite therapeutic effects of polyphenols in citrus peels.
