高效液相色谱-四极杆-静电场轨道阱高分辨质谱分析桑葚中黄酮类和多酚类物质

为了更好地利用桑葚这一药食同源果品,采用高效液相色谱-四极杆-静电场轨道阱高分辨质谱对桑葚提取物中黄酮类和多酚类成分进行分析研究。采用Syncronis C18色谱柱(100 mm×2.1 mm,1.7μm),以乙腈-0.1%甲酸水溶液为流动相,流速0.2mL/min,梯度洗脱分析。根据高分辨质谱提供的准分子离子峰和碎片离子信息,分析得到化合物的相对分子质量和结构信息。结合化合物的保留时间、对照品和相关文献数据,共鉴定出5种黄酮类成分和3种多酚类成分,分别为芦丁、异槲皮素、山奈酚-7-葡萄糖苷、二氢槲皮素、槲皮素、原儿茶酸、绿原酸和咖啡酸。通过讨论化合物的质谱碎裂规律,为化合物的结构鉴定提供依...

Summary:为了更好地利用桑葚这一药食同源果品,采用高效液相色谱-四极杆-静电场轨道阱高分辨质谱对桑葚提取物中黄酮类和多酚类成分进行分析研究。采用Syncronis C18色谱柱(100 mm×2.1 mm,1.7μm),以乙腈-0.1%甲酸水溶液为流动相,流速0.2mL/min,梯度洗脱分析。根据高分辨质谱提供的准分子离子峰和碎片离子信息,分析得到化合物的相对分子质量和结构信息。结合化合物的保留时间、对照品和相关文献数据,共鉴定出5种黄酮类成分和3种多酚类成分,分别为芦丁、异槲皮素、山奈酚-7-葡萄糖苷、二氢槲皮素、槲皮素、原儿茶酸、绿原酸和咖啡酸。通过讨论化合物的质谱碎裂规律,为化合物的结构鉴定提供依据。该方法可快速分析桑葚中黄酮类和多酚类成分,为合理开发桑葚的药用、食用价值奠定化学基础。
Bibliography:Mulberry has been widely researched for its unique health care effect.Its85% ethanol extract is included in the Chinese Pharmacopoeia.A method for analyzing the flavonoids and polyphenols of mulberry extracts was developed by high-performance liquid chromatography quadrupole-Orbitrap mass spectrometry.Most studies of mulberry focused on the content determination,extraction and separation,pharmacologicalactivities,while the analysis of active ingredients in mulberry flavonoids was seldom investigated.Studies have shown that the total content of flavonoids in the mulberry is1.508 mg/g.The research of flavonoids and polyphenols is of great significance to control the quality of medicinal and edible mulberry as well as to develop the valuable source reasonably.Recently,the HPLC/MS has been proved as an effective method for component analysis in complex extracts system,through which the compounds in mixtures and yield information based on their molecular weights as well as the structures can be rapidly determined.
