Bioactive Heterocycles VII ─ Flavonoids and Anthocyanins in Plants, and Latest Bioactive Heterocycles II

Fruits and vegetables contain abundant nutraceuticals or phytochemicals such as carbohydrates, proteins, lipids, vitamins, enzymes, dietary ?bers, min- als, antioxidants, ?avonoids, and anthocyanins and other diverse components including trace chemicals. Interestingly, the ?avonoids and anthocyanins in phytochemicals could be signi?cantly associated with reductions of risk of cardiovascular disease, macular degeneration, and improvements and prev- tions of many other diseases. Actually, ?avonoids and anthocyanins in plants could play a very important role in our daily health. Our ancestors used them as part of daily life for dyestuffs and folklore medicines. Evidentially, the bene?ts of colorful ?avonoids and anthocyanins have been con?rmed by the results of many researchers. As part of the series Topics in Heterocyclic chemistry,this volumetitled Bioactive Heterocycles II presents comprehensive and up-to-date reviews on - lected topics concerning mainly the usefulness for human health of ?avonoids and related compounds, Sophora ?avonoids and their functions in Sophora species (Leguminosae), the relationship of biological activity with the diverse structures of heterocycles by quantum chemical calculation, advances in bio- tive mesoionic heterocycles, and the spectroscopic properties and application of bioactive phenothiazines including also benzo[a]phenothiazines.
