枸杞子质量评价研究进展

Research progress on quality evaluation of Lycium barbarum

枸杞子为药食两用滋补类中药材,药用始见于《神农本草经》。枸杞子中含有枸杞多糖、枸杞黄酮、维生素、微量元素、氨基酸等多种成分,具有较高的药用价值和营养价值。随着对枸杞子质量评价研究的不断深入,发现不同种质、产地、采收时间、加工方式对枸杞子外观形态特征和营养成分含量有显著性影响。傅里叶变换红外光谱学、高效液相色谱法、NOSE、DNA等技术被应用于枸杞子鉴别及指纹图谱研究,可快速区分不同产地和不同品种枸杞。多种新技术、新方法被应用于枸杞多糖、甜菜碱、黄酮类、胡萝卜素类、有机酸、维生素、微量元素等活性成分定量检测中。枸杞有机氯、有机磷类农药残留组分检测不断增加,提升了安全性评价水平。这些相关研究成果,为枸杞子的质量标准提升和产业的深度发展提供价值参考。

Lycium barbarum is food and nutritious Chinese medicinal material,and its medicinal use began in Shen Nong′s Herbal Classic.Lycium barbarum contains many components such as Lycium barbarum polysaccharide,Lycium barbarum medlar flavonoids,vitamins,trace elements,amino acids,etc.,and has high medicinal value and nutritional value.With the deepening of the quality evaluation research,it was found that different germplasm,producing area,harvesting time and processing method had significant influence on the appearance,morphological characteristics and nutrient content of Lycium barbarum.Fourier transform infrared spectroscopy,high performance liquid chromatography,NOSE,DNA and other technologies are applied to the identification and fingerprinting of Lycium barbarum,which can quickly distinguish its origin and variety.A variety of new technologies and methods have been applied to the quantitative detection of active ingredients such as Lycium barbarum polysaccharides,betaines,flavones,carotene,organic acids,vitamins,and trace elements.The detection of organochlorine and organophosphorus pesticide residues in Lycium barbarum has improved the safety evaluation level.These related research results provide a valuable reference for the improvement of the quality standard of Lycium barbarum and the in-depth development of the industry.
