Abstract:
This study aims to investigate the total phenols and flavonoids contents of eight
hydroalcoholic extracts obtained from leaves and stems of medicinal plant belong of
Lamiaceae family. The Folin-Ciocalteu method was used to determine the total phenols
content while flavonoids were estimated according to the aluminum chloride colorimetric
method. The amounts of TPC were very high in the ethyl acetate and chloroform from leaves;
chloroform and ethyl acetate from stems. But the TFC were very elevated only in the ethyl
acetate extracts from leaves and stems. This medicinal plant which belongs of Lamiaceae
family collected from eastern Algeria possesses significant levels of TCP and TFC
