柑橘中类黄酮的前处理及检测技术研究进展

类黄酮化合物是含量最大的多酚类物质,具有抗氧化、抗癌、降低胆固醇等多种生理功能,在柑橘属中含量丰富,已经广泛应用于食品、医药和化妆品等领域。本文介绍了柑橘中类黄酮的种类结构,重点综述了近几年来柑橘中类黄酮活性成分的前处理技术,如固相萃取,闪式提取,超临界流体萃取、分子印迹技术,以及液相色谱、液质联用等检测技术。并分析了未来柑橘中活性成分的研究开发趋势。

Advances on pretreatment and determination technologies for flavonoids in citrus

Flavonoid compounds are the most abundant polyphenols which are rich in citrus and have strong antioxidant,anticancer effects,as well as lowering cholesterol levels and other physiological functions. They have been widely used in food,medicine and cosmetics etc. In this paper,the structure,the category of citrus flavonoids and physical and chemical properties were discussed,the pretreatment techniques of flavonoids from citrus in recent years were reviewed,such as solid phase extraction,flash extraction,supercritical fluid extraction,molecularly imprinted technology,the liquid chromatography(LC)and liquid chromatography-mass spectrometry(LC-MS)detection technology of citrus flavonoids was summarized in recent years. And the trend of research and development of active ingredients in citrus in the future was analyzed.
