FIGURE 5.

Partial least squares regression (PLS) plots of the correlations between phytochemical profile and antioxidative activities in kiwi berry extracts (a). Regression coefficients of different phytochemical profile on antioxidative activity (free peroxyl radical scavenging capacity [PSC] (b), bound PSC (c), total PSC (d), no PBS wash‐cellular antioxidant activity (CAA) (e), PBS wash‐CAA (f)). The antioxidative activities are in red font, and phytochemical profile are in blue font. Abbreviations of phenolic compounds: (+)‐gal, (+)‐gallocatechin; Caf, Caffeic acid; Chl, Chlorogenic acid; Pro B2, Poanthocyanidin B2; Pro C1, Poanthocyanidin C1; Pro, Protocatechuic acid; Q‐3‐O‐gal, Quercetin‐3‐O‐galactoside; Q‐3‐O‐glu quercetin‐3‐O‐glucoside; Q‐3‐O‐r quercetin‐3‐O‐rutinoside
