Fig. 2From: C. elegans as a test system to study relevant compounds that contribute to the specific health-related effects of different cannabis varietiesPrincipal component analysis (PCA) score plot of the 12 different genotypes based on 1H-NMR profiles of polar extracts (PF). This graph shows the differences in metabolic profiles of compounds in the extracts of the different varieties. PCA was performed using MetaboAnalyst 5.0 with auto-scaling. Green dots denote Δ9-tetrahydrocannabinol (THC)-rich varieties; brown dots denote cannabidiol (CBD)-rich varietiesBack to article page
