The basic flavonol nucleus is illustrated below. HO HO 0 kaempferol Substitutions, similar to some of those illustrated in the anthocyanins, also occur in the flavonol class. For example, other well known flavonols are quercetin (analogous to the anthocyanin cyanidin), and myricetin (analogous to the anthocyanin delphinidin). Flavonols are common flavonoid constituents and, like the anthocyanins, widely distributed
