      J. Chromatogr. A 1490, 201-211 (2017). HPTLC for comparison of the phenolic profiles of polar extracts from Populus nigra L. (1), Populus alba L. (2) and Salix alba L. (3) buds. Five chemotypical patterns were distinguished after derivatization with Natural Products reagent and confirmed by principal component analysis. The HPTLC analysis was directly hyphenated to various microbiological and biochemical assays as well as spectrometric techniques, which directly linked to active molecules in the chromatograms. The results showed that polyvalent compounds were evident when all derivatization and activity assays were combined together. Detection of at least three antimicrobial compound zones using Aliivibrio fischeri and Bacillus subtilis bioassays and of one phyto-estrogen with the planar yeast estrogen screen in Populus buds. Detection of several inhibitors of acetyl- and butyrylcholinesterase and rabbit liver esterase in all samples. Bioactive compounds were assigned by HPTLC-MS, e.g. chrysin as selective cholinesterase inhibitor, and caffeic acid and galangin as antimicrobials in (1) and (2). The method is suitable to determine the botanical origin and quality of Populus bud extracts and propolis samples.
