摘 要:Objective:To evaluate the antioxidant and antiglycation potential of polyphenols from three spices;alligator pepper,ginger and nutmeg.Methods:Polyphenol extracts of these spices were subjected to brine-shrimp lethality assay,phyloloxicily test,DPPH and superoxide anion radical scavenging as well as BSA-glucose antiglycation assay.Results:Results obtained showed that polyphenol extract of ginger has the highest anlioxidant potential with IC_(50)0.075 and 0.070 mg/mL.for DPPH and superoxide anion radical scavenging assay while alligator pepper displayed highest antiglycation activity with IC_(50)0.125 mg/mL.However,nutmeg extract exhibited weakest cytotoxic and phytotoxic potential with LD_(50)4359.70 and 1490μg/mL respectively.Conclusions: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.Objective:To evaluate the antioxidant and antiglycation potential of polyphenols from three spices;alligator pepper,ginger and nutmeg.Methods:Polyphenol extracts of these spices were subjected to brine-shrimp lethality assay,phyloloxicily test,DPPH and superoxide anion radical scavenging as well as BSA-glucose antiglycation assay.Results:Results obtained showed that polyphenol extract of ginger has the highest antioxidant potential with ICIC_(50) 0.075 and 0.070 mg/mL for DPPH and superoxide anion radical scavenging assay while alligator pepper displayed highest antiglycation activity with IC_(50) 0.125 mg/mL.However,nutmeg extract exhibited weakest cytotoxic and phytotoxic potential with LDIC_(50) 4359.70 and 1490 μg/mL respectively.Conclusions: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.
