Comparison of the metabolite profiles of three different types of palm wines. (A) PCoA using Bray–Curtis dissimilarity based on the palm wine metabolites profile generated by LC-HRMS shows a significant difference between the palm wine samples based on the palm tree species. The significance in the difference expressed as Bonferroni corrected p-values (q: 0.0001, F: 16.14, PERMANOVA). (B) The hierarchically clustered heat map shows the clustering of three different palm wine types based on the significantly differencing 21 metabolites (log2 fold change of >1 and q < 0.0001, Wilcoxon test, BH corrected). The concentration difference in the metabolites is shown with a red and blue colour gradient.
