摘要: 采用高效液相色谱法测定了5种柚汁中黄酮类物质、VC的含量。并用FRAP、DPPH及ABTS三种方法对其抗氧化能力做出评价。通过比较,得出佛柚汁中的柚皮苷含量、VC含量和总酚含量均为最高;除胡柚汁外,其他柚汁均未检测到橙皮苷和新橙皮苷;佛柚汁的抗氧化能力最强。酚类物质和VC则是柚汁中最主要的抗氧化物质。

Abstract: The contents of flavonoids and vitamin C in 5 kinds of pummelo juices were detected by HPLC method. And their antioxidant capacities were evaluated by methods of FRAP, DPPH and ABTS. Comparison results indicated that the contents of naringin, vitamin C and total phenolics in Foyou juice are the highest. Hesperidin and neohesperidin are not detected in pummelo juices except Huyou juice. The antioxidant capacity of Foyou juice is the highest. The most important antioxidant compounds are phenolics and vitamin C.
