HPTLC plates of representative samples of the studied Artemisia species (Tracks 1–3; A. annua total extracts, Tracks 4–6; A. herba-alba total extracts, Tracks 7–9; A. monosperma total extracts, Tracks 10–12; A. judaica total extracts) (A) Plate I viewed under UV at 366 nm [Tracks 13&14; Ref MIX 1 of umbelliferone (a), scopoletin (b) and aesculetin (c)]. (B) Plate I viewed in white light after post-chromatographic derivatization with anisaldehyde/sulphuric acid spray reagent [Tracks 13&14; reference artemisinin standard (d)]. (C) Plate II viewed under UV at 254 nm [Tracks 13&14; Ref MIX 2 of kaempferol (e), vitexin (g), quercetin-3-galactoside (h) and rutin (i) & phenolic acids; caffeic (f) and chlorogenic acids (j)] along with their untargeted PCA score scatter plots, HCA dendrograms and corresponding loading plots
