To evaluate the antioxidant and antiglycation potential of polyphenols from three spices; alligator pepper, ginger and nutmeg.
Polyphenol extracts of these spices were subjected to brine-shrimp lethality assay, phytotoxicity test, DPPH and superoxide anion radical scavenging as well as BSA-glucose antiglycation assay.
Results obtained showed that polyphenol extract of ginger has the highest antioxidant potential with IC50 0.075 and 0.070 mg/mL for DPPH and superoxide anion radical scavenging assay while alligator pepper displayed highest antiglycation activity with IC50 0.125 mg/mL. However, nutmeg extract exhibited weakest cytotoxic and phytotoxic potential with LD50 4359.70 and 1490 µg/mL respectively.
It can be concluded that the polyphenol extracts of alligator pepper, ginger and nutmeg displayed good antioxidant as well as antiglycation potential and are safe for consumption.
评估三种香料(非洲豆蔻、生姜和肉豆蔻)中多酚的抗氧化和抗糖化潜力。
对这些香料的多酚提取物进行卤虫致死率测定、植物毒性测试、DPPH和超氧阴离子自由基清除以及牛血清白蛋白-葡萄糖抗糖化测定。
所得结果表明,生姜的多酚提取物具有最高的抗氧化潜力,在DPPH和超氧阴离子自由基清除测定中IC50分别为0.075和0.070 mg/mL,而非洲豆蔻表现出最高的抗糖化活性,IC50为0.125 mg/mL。然而,肉豆蔻提取物表现出最弱的细胞毒性和植物毒性潜力,LD50分别为4359.70和1490 µg/mL。
可以得出结论,非洲豆蔻、生姜和肉豆蔻的多酚提取物具有良好的抗氧化和抗糖化潜力,食用安全。
