Bioactive component are rich in olive pomace.This paper mainly researched the component and antibacterial activity against Botrytis cinerea of olive pomace extracts.Firstly,olive pomace were extracted by heating reflux method with H₂O,50% ethanol,70% ethanol and 90% ethanol as extractants respectively and four extracts were obtained.And the component of extracts were analyzed by GC-MS and HPLC.Secondly,the extracts of the total phenol and antioxidant activity,antibacterial activity against B. cinerea were investigated.The results showed that among the four extracts,90% ethanol extract had high phenolic content,excellent antioxidant properties and obvious inhibitory effects on B. cinerea.This study provides a theoretical basis for the study of antibacterial properties of active components from olive pomace.
