HPTLC Analyses on Different Populations of Cistus salvifolius L

HPTLC was used as chromatographic tool to evidence chemical differences in plant extracts used in marketed botanical food supplements, i.e. populations of Cistus salvifolius L., collected in different parts of Europe, as case study. The obtained results evidenced either a corresponding fingerprint for the species and several quantitative differences, that were better valued by densitometric analysis. These data are noteworthy considering the actual interest of the aforementioned species by the botanical nutraceutical market and the general need for analytic tools adequate to botanicals contents.
