Antioxidant Effects on Oil and Antibacterial Activities of Extracts from Different Parts of Pomegranate
To study the antioxidant effects of extracts from the pericarp,leave,seed and flower(petal,stamen and receptacle) of pomegranate,their ethanolic extracts were added to soybean oil and lard respectively,and was in-spected by determining POV and MDA with the SCHALL heating oven method;the ability of scavenging free-radi-cals was measured by the DPPHo elimination method;additionally,the inhibiting effects of the samples on bacteria were compared.Results:The scavenging ability on DPPHo and the antioxidant effect on oil as well as the inhibiting effect to bacteria of the extracts ale very strong except those of the extract from seeds.The peficarp is the strongest one,and the petal,the stamen and the receptacle are of about a same level,but the leaf is weaker than them.The polyphenol content is significantly correlative to the antioxidant effect and antibacterial activity,which indicates that polyphenol is the main active compound.
