Sample origin discrimination with regard to fatty acid content. (A) Principal component analysis (PCA) score plot of the fatty acid profiles (in terms of relative abundance, %) for samples of Saccharina latissima from three different origins (FR—France, NO—Norway, UK—United Kingdom; one of the UK replicates was considered an outlier and was excluded from the analysis). (B) Box plots of the fatty acids used to calculate PCA ranging from major to lesser contributors for Principal Component 1 of the PCA (left to right, top to bottom).
