Application Notes

Alphitonin is a flavonoid-related metabolite related to quercetin isolated from the heartwood of the Australian red ash, Alphitonia excela in 1922. Alphitonin's structure was reported by Birch and Ritchie in 1960. Alphitonin is thermally and enzymically converted from the flavonoid, taxifolin. Alphitonin has antidiabetic and antioxidant properties, being more active than quercetin. In contrast, alphitonin did not inhibit TNF responses in a murine small intestinal epithelial cell line, suggesting that microbial transformation of quercetin completely abolished the latter’s anti-inflammatory effect.
