Abstract

This work centred on studying Algerian rosemary, where we focus on the part of stems to extract the most effective compounds. We use thin layer chromatography (CCM) technique to separate compounds, comparing the results with previous studies focused on leaves from rosemary plant. As a first step, we made the initial detection of some secondary metabolites, and then we extracted flavonoids using the Harborne ETOH/H2O method (70% 30%). After that, we separated some effective flavonoids using the thin layer chromatography of the previous three extracts. Chemical detection tests have shown that rosemary stalks contain effective compounds such as free and general flavonoids, saponics, sticks, unsaturated steroids, terpenes, alkaloids, and comarins, with the absence of glycoside flavonoids rosemary stems have a lower percentage of effective compounds compared to leaves.
