phytochemical caracterisation and biological activities of two medicinal plants harvested in algeria
The Algerian flora is characterized by its floral diversity, estimated at more than 3000 species belonging to several botanical families. Some of these plants are widely used in traditional medicine. Among these medicinal plants ; Daphne gnidium L. from the Thymelaeaceae family, known under the name of Lazzaz, and Ephedra alata alenda from the family of Ephedraceae ,these plants grows spontaneously in Algeria and has been recognized since antiquity for their medicinal properties. This study aims to enhance different extracts of these plants. Phytochemical caracterisation was carried out to determine the chemical composition, and the determination of total phenolic compounds including flavonoids of extracts was performed. Finally the antimicrobial activity was subsequently achieved by the agar disc method against four strains of bacteria. The results shows that the two species studied are rich in secondary metabolites including polyphenols and flavonoids. The hydrodistillation ensured the absence of essential oil, the studied extracts showed a low to medium activity against the bacterial strains. According to the study, Ephedra alata alenda and Daphne gnidium L. may be a useful medicinal plant for herbal medicine.

Ephedra alata alenda, PHYTOCHIMICAL CARACTERISATION AND BIOLOGICAL ACTIVITY
Abstract Several questions were raised concerning the safety of synthetic chemicals used in medicine or the food industry, the therapeutic limit of chemical drugs, the development of microbial resistance to antibiotics has led researchers to find new molecules with biological properties. In this context, this theme aims to study and enhance the alkaloids and phenolic compounds of a medicinal plant that grow spontaneously in Algeria: Ephedra alata alenda. Phytochemical tests were carried out to determine the chemical composition, the content of phenolic compounds including flavonoids of extracts of Ephedra alata alenda. The antimicrobial activity of polyphenols and alkaloids was subsequently achieved by the agar disc method. Species E. alata is rich in secondary metabolites, polyphenols and flavonoids are considered significant. The implementation of hydrodistillation ensured the absence of essential oil, also our plant showed low activity on S. aureus and E. coli, medium activity on B. thuringiensis and P. aeruginosa and no activity against C. albicans. According to the study, Ephedra alata alenda may be a useful medicinal plant for herbal medicine. Keyword: Ephedra alata alenda, phytochimical caracterisation, antimicrobial activity.

substances biactives de Pistacia lentiscus L.
Plusieurs questions ont été soulevées concernant la sécurité des produits chimiques synthétiques utilisés en médecine ou dans l’industrie alimentaire, la limite thérapeutique des médicaments chimiques, a conduit les chercheurs à trouver de nouvelles molécules aux propriétés biologiques en utilisons des produits naturels d'origine végétale. P. lentiscus L. est une plante médicinale de la famille des Anacardiacées, largement répandu dans les pays méditerranéens. Cette plante a été utilisée en médecine traditionnelle pour le traitement de plusieurs maladies, telles que les maladies gastro-intestinales, l’eczéma et les infections de la gorge, en raison de ses effets antioxydants, anti-inflammatoires et antimicrobiens. Ces propriétés favorables à la santé ont été attribuées à la présence de divers composés biologiquement actifs présents dans les différentes parties de la plante tels que la résine, les feuilles, l’huile fixe, et l’huile essentielle. Due à sa richesse en substances bioactives cette plante a fait l’objet de plusieurs recherches, dans cette étude nous donnant un aperçu sur ces substances.

Daphne gnidium L., PHYTOCHIMICAL CARACTERISATION AND BIOLOGICAL ACTIVITIES
Several questions were raised concerning the safety of synthetic chemicals used in medicine or the food industry, the therapeutic limit of chemical drugs, the development of microbial resistance to antibiotics has led researchers to find new molecules with biological properties. Daphne gnidium L. is a medicinal plant from the Thymelaeaceae family, known in Algeria under the name of Lazzaz, it grows spontaneously in Algeria and has been recognized since antiquity for its antiseptic, insecticide, depurative, healing and sudorific properties. In this context, this theme aims to study and enhance the aqueous and methanolic extract of this plant. Phytochemical caracterisation was carried out to determine the chemical composition, and the determination of total phenolic compounds including flavonoids of Daphne gnidium L. extracts was performed. Besides the antimicrobial activity which was subsequently achieved by the agar disc method against four strains of bacteria. Keywords: Daphne gnidium, phytochemicals caracterisation, antimicrobial activity.

Pistacialentiscus L., a plant with promising pharmacological power
The Algerian flora is characterized by its floral diversity, estimated at more than 3000 species belonging to several botanical families. Some of these plants are widely used in traditional medicine.Among these medicinal plants Pistacia lentiscus. P. lentiscusis a Mediterranean shrub of the Anacardiaceae family commonly known as lentisk.It develops in several Mediterranean regions such as Algeria where it is generally scattered all along the coast.P. lentiscus has been known since antiquity for its medicinal properties, which justifies its wide use in the Arab and European pharmacopoeia to treat several pathologies such as gastrointestinal disorders, eczema and respiratory inflammations.It should be emphasized that all parts of Plentiscus have medicinal uses. The fruit oil is used internally for respiratory allergies, externally to treat sore throats, and locally applied for wounds and burns.Moreover; the organic extracts and essential oil are known by their anti-inflammatory activity.Other properties are attributed to P. Lentiscus such as antioxidant capacity, antimicrobial activity and hepatoprotective and neuroprotective action.

Pistacia Lentiscus L. ESSENTIAL OIL, BIOLOGICAL AND PHARMACOLOGICAL EFFECTS
Pistacia lentiscus L. is an evergreen shrub of the Anacardiaceae family commonly called “Derw” in local Arabic. It develops in several Mediterranean regions such as Algeria where it is generally scattered all along the coast. This plant is known for its medicinal properties since antiquity, it was recommended mainly to treat skin problems (burns, eczema), lung affections (bronchitis, allergy, asthma) and gastrointestinal disorders .The essential oil of Pistacia lentiscus L. is used for its pharmacological effects as antidiabetic, anti-inflammatory, antioxidant, antifungal and antibacterial. It is also used as a flavoring agent in food preparations, in cosmetics, and perfumery. This oil is obtained by water distillation of leaves, fruits or from trunk exudates (mastic gum).Several studies on the chemical composition of P. lentiscus oil have been carried out and have shown the presence of different compounds, flavonoids, triterpenes and volatiles. It contains longifolene, myrcene, α-pinene, limonene and p-cymene. A study suggests that P. lentiscus from Algeria belongs to terpinen-4-ol, α-terpineol, germacrene D-chemotype, which could be a new chemotype. In the present study we conducted to investigate the importance of essential oil of Pistacia lentiscus L.

Pistacia lentiscus L. FRUIT OIL, A BIORESSOURCE WITH PHARMACOLOGICAL POWER
In recent years, there has been a growing interest in bioresources. Among these bioresources, the fixed oil of Pistacia lentiscus. P. lentiscus, an evergreen shrub of the Anacardiaceae family, is widely distributed tree in the Mediterranean area.The fruit of P. lentiscus provides edible oil which is rich in unsaturated fatty acids as oleic and linoleicand widely used in traditional medicinein the prevention and treatment of a wide variety of diseases.This oil is also considered as a nutritional source.Several reports indicated the limited geographical distribution of lentisk oil users with predominance use is linked to traditional pharmacopoeia of eastern and central parts of Algeria and Tunisia.Lentiscusfruit oil is often used as an external remedy applied locally as an ointment to treat burns or back pain, orally for respiratory problems of allergic originbut also as ethnomedical remedy for the treatment of gastrointestinal upsets, gastric ulcers, skin illness and inflammatory diseases as soothing massage or internal use.Also, this oil is used in the manufacture of anti-diarrheal pills and protects against mercury poisoning. The aim of this study is to validate the importance of P. lentiscusfruit oil asmultipurpose pharmaceutical potential.
