研究5种木槿花卉及其不同极性溶剂萃取物的生物活性物质含量和抗氧化活性,分析它们之间的相关性,并采用高效液相色谱-串联质谱鉴定其中的活性物质成分,以期为木槿深加工及其品种选育提供理论依据。 5个品种木槿花的总酚和总黄酮含量从高到低依次为木槿原种、粉紫重瓣木槿花、薰衣草薄绸木槿花、紫玉和雅致木槿,各品种木槿花的抗氧化活性排序与其总酚和总黄酮含量排序基本一致,其中木槿原种的总酚和总黄酮含量最高,分别达到了17.33 mg/g和12.68 mg/g,且抗氧化活性最强,其总还原能力、1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基清除能力、2,2'-联氨-双-3-乙基苯并噻唑啉...

This study aimed to investigate and correlate the bioactive components and antioxidant activity of flowers from five varieties of Hibiscus syriacus and different polar solvent extracts from Hibiscus syriacus L. for the purpose of providing a theoretical basis for deep processing and breed of hibiscus flower. The bioactive components were identified by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The results showed that the contents of total polyphenols and total flavonoids in five varieties of Hibiscus syriacus were consistently in the decreasing order of Hibis...
