From: NMR-based metabolomics of water-buffalo milk after conventional or biological feeding
Score-plot of principal component analysis (PCA) based on 13C NMR spectra of the phospholipids (PL) fraction extracted from milk creams of CFM (green circles, collected in 2010) and BFM (light brown rhombi, collected in 2011) samples (19.5% of total variance explained). The figure reports exclusively the name and the direction of loading-vectors which significantly differentiated CFM from BFM samples
