A qualitative and quantitative study has been performed using the chromatographic method associated with photodensitometry of the tincture obtained from fresh and dry Hibiscus trioni Herba. Using thin layer chromatography followed by photodensitometry it have been shown that both tincture are rich in polyphenols (flavonoids and carboxylic compounds), and free amino acids in significant quantities. The results indicate that fresh Hibiscus trioni Herba have higher concentrations of active ingredients which support the hypothesis that plants can not be kept dry for a long time without loosing their properties.
