Abstract
The pro-and anti-oxidant properties of raspberry and blackberry from different varieties harvested at different stages of maturity were analyzed by multivariate analysis.The results of one-way analysis of variance(one-way ANOVA) showed that Triple Crown,,fruits contained even higher contents of GSH,total phenolics and total flavonoids than other varieties tested had lower total anti-oxidant capacity(TAC) at higher maturity.In addition,both variety and maturity showed more significant impact on the contents of GSH,total phenolics and MDA and hydroxyl radical-scavenging capacity in raspberry and blackberry.The results of principal component analysis(PCA) showed that variety had greater impact on TAC antioxidant capacity as compared with maturity.The results of correlation analysis and partial least squares regression(PLSR) indicated that H2O2 content was positively correlated with MDA content,GSH content or superoxide anion radical-scavenging capacity,whereas total phenolics content was positively correlated with TAC,hydroxyl radical-scavenging capacity or DPPH radical-scavenging capacity.The results of path coefficient analysis showed that the contents of total phenolics and total flavonoids had the most obvious effect on H2O2 content.
