以抗坏血酸(VC)为对照,考察了茶多酚(TP)、螺旋藻(SP)及其复配物对·OH、O2-·和DPPH自由基的清除能力,进而分析它们的抗氧化性能。结果表明,TP、SP对·OH、O2-·和DPPH自由基都具有一定的清除能力,且在研究浓度范围内其清除率都随待测样品浓度增加而增强。TP清除自由基的能力优于SP,且TP对·OH、DPPH自由基的清除能力与VC相当,SP对·OH自由基的清除能力较强而对DPPH自由基的清除能力很弱;向SP中添加10%左右的TP,即表现出较强的协同抗氧化性能,这对进一步研发适宜于中、老年人服用的兼有抗氧化和增强免疫力的营养保健食品具有重要的参考价值。
以抗壞血痠(VC)為對照,攷察瞭茶多酚(TP)、螺鏇藻(SP)及其複配物對·OH、O2-·和DPPH自由基的清除能力,進而分析它們的抗氧化性能。結果錶明,TP、SP對·OH、O2-·和DPPH自由基都具有一定的清除能力,且在研究濃度範圍內其清除率都隨待測樣品濃度增加而增彊。TP清除自由基的能力優于SP,且TP對·OH、DPPH自由基的清除能力與VC相噹,SP對·OH自由基的清除能力較彊而對DPPH自由基的清除能力很弱;嚮SP中添加10%左右的TP,即錶現齣較彊的協同抗氧化性能,這對進一步研髮適宜于中、老年人服用的兼有抗氧化和增彊免疫力的營養保健食品具有重要的參攷價值。

The antioxidant properties such as scavenging the free radicals towards hydroxyl radical (·OH), superoxidized anionic radical (O2-·) and 1,1-diphenyl 2-picrylhydrazyl (DPPH) by tea polyphenols (TP), spirulina(SP) and their mixed compounds were investigated through using ascorbic acid (VC) as the contrast. The results showed that TP and SP had a certain scavenging activities to ·OH,O2-· and DPPH,and the scavenging ratio increased with the concentration of TP,SP and their mixed compounds in the range of the investigated concentration. The TP's scavenging abilities to·OH,O2-·and DPPH was better than SP's,and equivalent to VC in its scavenging activities to ·OH and DPPH. SP had a good scavenging abilities to ·OH but bad to DPPH. TP and SP mixed compounds showed strong synergistic antioxidant properties if 10 %of TP was added into SP ,the results provied an important reference for the further research and development of health-care food which play a role of enhance immune and antioxidant properties and the health-care food was suitable for the middle-aged and elderly.
