Jujube is a homologous herb of medicine and food, and polyphenols are key in determining the functional effects of jujubes.
In this study, characteristic polyphenols in 15 varieties of Chinese jujubes were investigated based on untargeted metabolomics.
The results showed that a total of 79 characteristic polyphenols were identified in the 15 varieties of Chinese jujube, and 55 characteristic polyphenols such as syringetin, spinosin and kaempferol were reported for the first time. Scopoletin (63.94% in LZYZ), pectolinarin (22.63% in HZ) and taxifolin (19.69% in HZ) contributed greatly and presented significant ( < 0.05) differences in the 15 varieties of Chinese jujubes. HZ was characterized by pectolinarin, erianin and wogonoside, while XSHZ, NYDZ and RQHZ, with similar polyphenol profiles, were characterized by (+)-catechin, combretastatin A4 and tectorigenin. JSBZ, HMDZ, TZ, JCJZ and HPZ had similar polyphenol profiles of galangin, isoferulic acid and hydroxysafflor yellow A.
Metabolomics is critical in grasping the full polyphenol contents of jujubes, and the differences in the polyphenol profiles and characteristic individual polyphenols of the 15 varieties of Chinese jujubes were well analyzed by principal component analysis (PCA).
枣是药食同源的草本植物，多酚是决定枣功能作用的关键成分。
本研究基于非靶向代谢组学对15个枣品种的特征性多酚进行了研究。
结果表明，在15个枣品种中共鉴定出79种特征性多酚，其中紫丁香亭、斯皮诺素和山奈酚等55种特征性多酚为首次报道。 scopoletin（在LZYZ中占63.94%）、pectolinarin（在HZ中占22.63%）和taxifolin（在HZ中占19.69%）在15个枣品种中贡献较大且存在显著（<0.05）差异。HZ的特征成分是pectolinarin、毛蕊异黄酮和汉黄芩苷，而XSHZ、NYDZ和RQHZ的多酚谱相似，其特征成分是（+）-儿茶素、Combretastatin A4和鸢尾黄素。JSBZ、HMDZ、TZ、JCJZ和HPZ具有相似的多酚谱，其特征成分是高良姜素、异阿魏酸和羟基红花黄色素A。
代谢组学对于全面掌握枣的多酚含量至关重要，通过主成分分析（PCA）很好地分析了15个枣品种的多酚谱和特征性单体多酚的差异。
