中文摘要：

燕麦（Avena sativa L．）是一种公认的有益心脏健康的食品，其保健功能除归因于高含量的β-葡聚糖外，还因其富含多种功能成分，如植酸、维生素E、黄酮类和超过20种的燕麦生物碱等。燕麦生物碱是燕麦特有的酚酸类衍生物，具有多种生物活性，对人类和动物健康非常有益。最新研究表明，燕麦生物碱兼有抗炎、抗增殖和止痒等生物活性，对于冠心病、结肠癌和皮肤瘙痒等疾病的防治起到重要的作用。本文对燕麦生物碱的结构分布、保健作用及其生物合成作了系统的阐述，对于开发燕麦新产品、提高燕麦产品附加值具有重要意义。

英文摘要：

Oats（Avena sativa L. ）are a well -known healthy food benefiting the heart mainly due to their high β - glucan content. In addition, they contain other functional compounds, such as phytic acid, flavonoids, vitamins E, and more than 20 avenanthramides. Avenanthramides are phenolic compounds uniquely produced in oats and have many beneficial properties related to human and animal health. The avenanthramides of oats have also recently been shown to exhibit anti - inflammatory, antiproliferative, and anti - itching activity, which may provide additional protec- tion against coronary heart disease, colon cancer, and skin irritation. In this paper, the structural distribution, biosyn- thesis and health benefits of avenanthramides were overviewed systematically, which was helpful for developing the new products and increasing the additional value of oats.
