Factor loadings of the eleven variables used in the principal component analysis on the first two principal components (PC1, PC2).

<p>FRAP_F = FRAP activity of free polyphenol fraction; FRAP_B = FRAP activity of bound polyphenol fractions; DPPH_F = DPPH activities of free polyphenol fraction, DPPH_B = DPPH activities of bound polyphenol fraction; F/P = ratio of total flavonoids on total polyphenols, TNF = total number of free polyphenol species (including isomeric forms), TNB = total number of bound polyphenol species (including isomeric forms); ML = MTT viability test on leukemic cell line; RL = ROS test on leukemia cell line; MC = MTT viability test on cardiomyocytes; RC = ROS test on cardiomyocytes.
