标题:Antioxidant Activity Of Hydroxytyrosol Acetate Compared With That Of Other Olive Oil Polyphenols
摘要:Hydroxytyrosol Acetate Was Synthesized,And The Antioxidant Activity Of This Olive Oil Component Was Assessed In Comparison With That Of Other Olive Oil Components,Namely Hydroxytyrosol,Oleuropein,3,4-Dhpea-Ea,And Alpha-Tocopherol In Bulk Oil And Oil-In-Water Emulsions. The Activity Of The Compounds Was Also Assessed By Scavenging Of 1,1-Diphenyl-2-Picrylhydrazyl (Dpph) Radicals. Hydroxytyrosol Acetate Had A Weaker Dpph Radical Scavenging Activity Than Hydroxytyrosol,Oleuropein,Or 3,4-Dhpea-Ea But It Had A Radical Scavenging Activity Similar To That Of Cr-Tocopherol. In Oil,The Antioxidant Activity Of Hydroxytyrosol Acetate Was Much Higher Than That Of Alpha-Tocopherol Or Oleuropein,But In An Emulsion S,4-Dhpea-Ea And Alpha-Tocopherol Were More Effective As Antioxidants Than Hydroxytyrosol Acetate. The Antioxidant Activity Of Hydroxytyrosol Acetate Was Rather Similar To That Of Hydroxytyrosol In Oil And Emulsions Despite The Difference In Dpph Radical Scavenging Activity.

摘要:The olive leaf extract silver nanoparticles may be synthesized by extracting olive leaves and using the extract to synthesize AgNPs. Olive leaves may be washed, dried, and ground to a powder. The olive leaf powder may be mixed with a first solvent to form a first olive leaf extract. The first olive leaf extract may then be separated and/or concentrated by centrifugation and filtration to form a filtrate. The filtrate may be evaporated to form a residue. The residue may then be resuspended in ethanol to form a second olive leaf extract. The second olive leaf extract may be mixed with AgNO 3 to form a mixture including the AgNPs.
