A GC analysis was carried out for achieving this purpose. 
GC
Subsequently, total polyphenol content (TPC) and antioxidant activity measured by DPPH, FRAP and BCB assays were evaluated. 
DPPH
Subsequently, total polyphenol content (TPC) and antioxidant activity measured by DPPH, FRAP and BCB assays were evaluated. 
FRAP
Subsequently, total polyphenol content (TPC) and antioxidant activity measured by DPPH, FRAP and BCB assays were evaluated. 
BCB
Three different statistical methods: Relative Antioxidant Capacity Index (RACI), Pearson's correlation coefficient (r) and PCA, were used to compare results obtained and underline EO relationships. 
PCA
