黄酮类化合物与植物中广泛分布的类黄酮亚族相对应，根据它们是否含有C-糖基化或O-糖基化和羟化B-环，可以通过不同的途径合成。黄酮类正在成为参与植物信号传递和防御的非常重要的专门代谢物，以及人类饮食的关键成分，具有显著的健康益处。在这里，我们评价植物中黄酮类的形成，强调生物合成途径决定黄酮类化学这一新兴主题。此外，我们从黄酮类化合物在生物和非生物植物相互作用中所起的作用，以及它们作为人和动物饮食中营养成分的作用两个方面，简要地综述了它们的生物活性。
Flavones correspond to a flavonoid subgroup that is widely distributed in the plants, and which can be synthesized by different pathways, depending on whether they contain C- or O-glycosylation and hydroxylated B-ring. Flavones are emerging as very important specialized metabolites involved in plant signaling and defense, as well as key ingredients of the human diet, with significant health benefits. Here, we appraise flavone formation in plants, emphasizing the emerging theme that biosynthesis pathway determines flavone chemistry. Additionally, we briefly review the biological activities of flavones, both from the perspective of the functions that they play in biotic and abiotic plant interactions, as well as their roles as nutraceutical components of the human and animal diet.
