油梨不同部位总酚含量、抗氧化及抗菌活性
Total Phenolic Content,Antioxidant and Antimicrobi-al Activities from Different Parts of Avocado Perseaa-mericana Mill
摘要
Abstract
[Objective]The aim was to investigate 50% methanol extracts of different parts (peel,pulp and seed,leaf)from avocado (Persea americana Mill.)for total phenolic con-tent,in vitro antioxidant activity,and antimicrobial activities.The correlation between an-tioxidant activity and total phenolic content was also analyzed.[Methods]The contents of to-tal phenol were measured by Folin-Ciocalteau assay.In vitro antioxidant activity was evalua-ted using the DPPH·assay.Correlation between antioxidant activity and total phenolic content was analyzed by using the Bivariate correlation analysis of SPSS 1 9 .0 version.Antimicrobial ac-tivities were performed by disk diffusion.[Re-sults]Peel had a higher phenolic content than seed and leaf,whereas the pulp’s was the low-est.Peel,seed and leaf had more intense in vitro <br> antioxidant potential than the pulp.The positive correlation between the antioxidant capacity and total phenolic content was significantly (P<0.05),which correlation coefficient was up to 0.983.In other words,the antioxidant capacity was enhanced along with the increase of to-tal phenolic content.The peel and the seed displayed moderate antimicrobial effects against Staphylococcus aureus,but had no inhibitory effects againstCandidaalbicans.[Conclusion]The avocado shows great intense in antioxidant potential and moderate antimicrobial effects, which provide a scientific basis to the research about comprehensive development and utiliza-tion of the avocado.关键词
