In this paper,the total phenols and antioxidant capacity of H-CFC(heat-treatment camellia seed oil filter cake)and NH-CFC(non-heat treatment camellia seed oil filter cake)were investigated by methanol,acid hydrolysis and alkali hydrolysis,respectively.The active components in the heat-treatment filter cake(H-CFC)and the non-heat treatment filter cake(NH-CFC)were extracted by using methanol,the acid hydrolysis method,and the alkali hydrolysis method,respectively,in order to investigate the antioxidant capacity of the filter cake created by the filtration process of camellia seed oil.The results indicated that the direct addition of 1％H-CFC significantly increased the induction period(IP)of H-CSO(heat-treatment camellia seed oil),while the direct addition of NH-CFC had no significant effect on the IP of NH-CSO(non-heat treatment camellia seed oil).The total phenolic content of the methanolic extracts of H-CFC and NH-CFC was 339.5 and 234.5 times higher than that of the unfiltered camellia seed oil,respectively.The total phenol content,DPPH scavenging capaci-ty,ABTS capacity,and FRAP capacity of the methanolic extract of the H-CFC were 1.45,1.75,1.19,and 1.97 times higher than those of the methanolic extract of the NH-CFC,respectively.The total phenol content,DPPH scavenging capacity,ABTS scavenging capacity,and FRAP reduction capacity of acid-hydrolysed H-CFC ex-tracts were 1.27,4.91,2.93,and 5.67 times higher than those of base-hydrolysed samples,respectively;the total phenol content,DPPH scavenging capacity,ABTS scavenging capacity,and FRAP reduction capacity of acid-hydrolysed NH-CFC extracts were 1.67,2.61,11.50,and 3.47 times higher than those of base-hydrolysed samples,respectively.Camellia seed oil filter cake can be considered as an excellent source of natural antioxida-nts.
