Anthocyanins are high-value compounds, and their use as functional foods and their natural colorant have potential health benefits. Anthocyanins seem to possess antioxidant properties, which help prevent neuronal diseases and thereby exhibit anti-inflammatory, chemotherapeutic, cardioprotective, hepatoprotective, and neuroprotective activities. They also show different therapeutic effects against various chronic diseases. Anthocyanins are present in high concentrations in onion. In recent years, although both conventional and improved methods have been used for extraction of anthocyanins, nowadays, improved methods are of great importance because of their higher yield and stability of anthocyanins. In this review, we compile anthocyanins and their derivatives found in onion and the factors affecting their stability. We also analyze different extraction techniques of anthocyanins. From this point of view, it is very important to be precisely aware of the impact that each parameter has on the stability and subsequently potentiate its bioavailability or beneficial health effects. We present up-to-date information on bioavailability, dietary effects, and health implications of anthocyanins such as antioxidant, antidiabetic, anticancerous, antiobesity, cardioprotective, and hepatoprotective activities.
花青素是高价值化合物，将其用作功能性食品和天然色素具有潜在的健康益处。花青素似乎具有抗氧化特性，有助于预防神经疾病，从而展现出抗炎、化疗、心脏保护、肝脏保护和神经保护活性。它们对各种慢性疾病也显示出不同的治疗效果。洋葱中花青素含量很高。近年来，虽然传统方法和改进方法都被用于提取花青素，但如今，改进方法因其花青素产量更高且稳定性更好而至关重要。在本综述中，我们汇总了洋葱中发现的花青素及其衍生物以及影响其稳定性的因素。我们还分析了花青素的不同提取技术。从这一角度来看，准确了解每个参数对稳定性的影响并随后增强其生物利用度或有益健康效果非常重要。我们提供了关于花青素生物利用度、饮食影响和健康意义的最新信息，例如抗氧化、抗糖尿病、抗癌、抗肥胖、心脏保护和肝脏保护活性。
