(A) Concentration of Sceletium metabolites in different species and populations found at twelve locations. Horizontal stacked columns represent metabolites (mg/kg DW) tentatively identified chemical markers responsible for metabolomic separations. Each horizontal stacked column represents up to 10 individuals per location and/or taxon S. tortuosum B-R) Concentration of tentatively identified metabolites (mg/kg DW) in S. strictum, S. emarcidum, S. tortuosum and S. emarcidum found at different locations: (B) Mesembrine; (C) Mesembranol; (D) Δ7-Mesembrenone; (E) Mesembrenone; (F) Mesembrenol; (G) O-methyldehydrojoubertiamine; (H) Sceletium A4; (I) Sceletium A4 isomer; (J) Epimesembranol; (K) 4'-O-Demethylmesembrenone; (L) Epimesembrenol; (M) Dihydrojoubertiamine; (N) 4'-O-Demethylmesembrenone isomer; (O) 4-(3,4-dimethyoxyphenyl)-4-[2-acetylmethlamino)ethyl]cyclohexanone; (P) O-acetylmesembrenol; (Q) 4'-O-demethylmesembrenol; (R) Δ7 4'-O-Demethylmesembrenol.
