<strong>Abstract</strong>: The Lamiaceae family is represented in Algeria by 28 genus and 146 species. Among
this family, many plants of the genus are widely used in local herbal medicine, as they show a
wide range of pharmacological activities. The purpose of this research concerns the phytochemical
and the biological study of one of the Algerian flora‟s medicinal plants known as Retura lutea. The
diverse methods of separation and purification of the methanolic extract of the Retura lutea to
obtain two flavonoid c-glucosides. The structure elucidation of the isolated compounds was based
on analyses of their spectroscopic data (1D and 2D NMR, UV, MS).
Key words: Algerian Reutera lutea, chemical, extract.

<strong>Abstract</strong>: Polyphenols, a group of structurally heterogeneous compounds, have
been widely used in phytotherapy for a long time. Quantitative analysis of total
phenolic compounds using Folin-Ciocalteu reagent were used to determine total
phenols of plant extracts and the quantitative analysis of flavonoids was
performed by the spectrophotometric assayas described by Kim et al. The
quantitative dosage of total phenolic and flavonoids showed that Osyris
uadripartite Salzm. And Pistacia atlantica Desf. Were the richest in phenolic
compounds (425,43 ± 5,89 – 385,56 ± 8,43 mg GAE/g dry matter), contrary
Rosmarinus officinalis L. and Acacia raddiana Savi presents highest content on
flavonoids (123,56 ± 8,67 – 110,32 ± 9,12 GAE/g dry matter).
Key words: Flavonoids, medicinal plants, polyphenols, secondary metabolites.
