花生红衣研究进展

摘要

花生是我国的优势种植作物，产量位居世界首位，但是缺少深度开发，花生红衣的利用率低下。花生红衣是重要粮油作物花生(Arachis hypogaea .L)的种皮，同时也是一味传统中药。花生红衣中的化学成分主要是原花青素，根据成分的聚合度进行分类。原花青素具有很强的生物活性，如抗氧化、降血脂、降血糖和抗过敏等，又具食源性和低毒性的特点，因此在食品和药品领域有巨大的应用前景和实用价值。本文对花生生产的基本情况、花生红衣的化学成分、生物活性和应用前景进行了详细综述。%Peanut is an important crop as food and oil, while its seed skin is also known as a tradi-tional Chinese medicine.This review compiled reports of procyanidins at home and abroad, introduced the chemical compositions, biological activities and the application prospect of peanut skin in detail. Peanut is an important plant in China, with the highest production over the world.But there are much peanut skin wasted in the processing of peanut-derived products.The main chemical compositions in peanut skin were procyanidins, which were classified according to the polymerization degree, with fig-ures to illustrate each compound.This paper summarized the current knowledge on the biological ac-tivities, such as antioxidant and antiallergic activity, inhibition on hyperlipidemia and diabetes, etc. Based on the latest studies at home and abroad, peanut skin is considered to be with great application in the field of food and medicine for its strong antioxidant activities and low toxicity.
