THE CHEMICAL COMPOSITION, BIOLOGICAL ACTIVITIES, AND TRADITIONAL USES OF LAVANDULA MULTIFIDA L. IN THE MEDITERRANEAN.
THE CHEMICAL COMPOSITION, BIOLOGICAL ACTIVITIES, AND TRADITIONAL USES OF LAVANDULA MULTIFIDA L. IN THE MEDITERRANEAN. ALLOUANI Mohammed 1, 2*, HENDEL Noui 1, 2, MOUTASSEM Dahou 3 1Microbiology and Biochemistery Departement, Faculty of Sciences, University of M’sila 2Laboratory of Biology: Applications in Health and environment 3Laboratory of Characterization and Valorization of Natural Resources, Faculty of Nature and Life Sciences, Mohamed El Bachir El Ibrahimi University, Bordj Bou Arreridj, Algeria *E-mail : mohammed.allouani@univ-msila.dz Abstract Lavandula multifida L., commonly known as Egyptian lavender or fern-leaf lavender, is a semi-evergreen perennial shrub belonging to the Lamiaceae family. It is the only Pterostoechas section species found in abundance in the Mediterranean region thriving in poorly-evolved limestone soils and hot, arid climatic conditions. This herb is traditionally used to treat a lot of conditions, such as colds, gastrointestinal issues, asthma, arthritis, rheumatoid arthritis, hypertension, and uterine irritation. Lavandula multifida essential oil is composed of various components, including oxygenated monoterpenes, sesquiterpene hydrocarbons, monoterpene hydrocarbons, and oxygenated sesquiterpenes. Carvacrol has been shown to be the primary compound in L. multifida L. essential oil, contributing significantly to its flavor and biological activities. Many investigations have revealed the plant's biological properties, which include antibacterial, antifungal, antioxidant, and anti-inflammatory actions. The L. multifida essential oil also holds substantial value in the perfume, cosmetic, flavoring, and pharmaceutical industries. Keywords: L. multifida L., traditional uses, chemical composition, essential oils, carvacrol, biological activities.

TOTAL PHENOLIC CONTENTS, IN VITRO ANTIOXIDANT, ANTIBACTERIAL, AND ANTIFUNGAL ACTIVITIES OF THE ALGERIAN OTOSPERMUM GLABRUM (LAG.) WILLK. EXTRACTS
TOTAL PHENOLIC CONTENTS, IN VITRO ANTIOXIDANT, ANTIBACTERIAL, AND ANTIFUNGAL ACTIVITIES OF THE ALGERIAN OTOSPERMUM GLABRUM (LAG.) WILLK. EXTRACTS ALLOUANI Mohammed 1, 2*, HENDEL Noui 1, 2, MOUTASSEM Dahou 3 1Microbiology and Biochemistery Departement, Faculty of Sciences, University of M’sila 2Laboratory of Biology: Applications in Health and environment 3Laboratory of Characterization and Valorization of Natural Resources, Faculty of Nature and Life Sciences, Mohamed El Bachir El Ibrahimi University, Bordj Bou Arreridj, Algeria *E-mail : mohammed.allouani@univ-msila.dz ABSTRACT Medicinal plants include diverse plant types used in herbalism, many of which have medicinal properties. They serve as valuable resources for drug development and synthesis. Otospermum glabrum (Lag.) Willk., belonging to the Asteraceae family, is known by its synonyms, including Matricaria glabra (Lag.) Ball, Pyrethrum glabrum Lag., and Otocarpum glabrum (Lag.) Willk. This plant is also recognized as a species of chamomile and is widely used in traditional medicine. The objective of this study is to determine the total phenols and the total flavonoids contents and to evaluate in vitro the antioxidant, antibacterial, and antifungal activities of the methanolic, ethyl acetate, and aqueous extracts prepared from the aerial parts of the Algerian Otospermum glabrum (Lag.) Willk. The total phenolic and flavonoid contents were determined spectrophotometrically. The antioxidant activity of the extracts was examined by two different methods, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the β-Carotene bleaching test. The antibacterial activity was achieved through the well diffusion technique against seven bacterial strains, and the antifungal activity of the methanolic extract was determined using the contact assay against eight fungal strains. The results showed that the ethyl acetate extract presented the highest total phenols and total flavonoids contents (65.641±1.419 µg GAE/mg extract and 51.539± 0.468 µg QE/mg extract) compared with the metabolic (49.163±0.834 µg GAE/mg extract and 21.767± 0.623 µg QE/mg extract) and aqueous extracts (19.654±0.287 µg GAE/mg extract and 8.491± 0.078 µg QE/mg extract). The methanolic extract displayed the highest antioxidant activity in both DPPH and β-Carotene bleaching tests, with IC50 values of 53.217±0.428 and 2.725 ± 0.235, respectively. When compared to the standard antioxidant BHT, all extracts exhibit lower activity. In general, the tested bacteria can be characterized as sensitive, with inhibition diameters ranging from 9.65 to 14.85 mm, except for E. faecalis, which exhibited resistance to the tested extracts. The antifungal activity showed a significant inhibition varying from 25% to 50%, according to the tested fungal species, of which Penicillium expansum stain was the most sensitive with an inhibition of 50%. Key Words : Otospermum glabrum, phenolic contents, antioxidant activity, antibacterial activity, antifungal activity.

IMPORTANCE DU GENRE LAVANDULA EN ALGERIE
Depuis l’antiquité, les grandes civilisations ont eu recours aux plantes médicinales pour leurs propriétés diverses. L’Algérie, grâce à sa position géographique au centre de la méditerranée, est considérée comme une source très riche et diversifiée de plantes aromatiques. Parmi ces plantes aromatique la lavande. Le genre Lavandula est un membre de la famille des Lamiaceae. Les espèces de ce genre sont des arbustes aux sous-arbrisseaux avec un large éventail de parfums. De nombreuses espèces de ce genre sont rencontrées dans la flore algérienne : L. stoechas L., L. multifida L., L. dentata L et L. antineae Maire, qui poussent spontanément dans tout le pays. La Lavande occupe une place significative en médecine traditionnelle Algérienne ; elle peut être utilisée comme agent antiseptique, stimulant, et pour le traitement de rhume et d’hypotension. De nombreuses études ont montré que les huiles essentielles ou les extraits de lavande présentent une large gamme d’activités biologiques : antimicrobienne, anti-inflammatoire, antioxydante, sédative et insecticide. Les espèces de Lavandula sont des plantes aromatiques et médicinales très utiles avec une valeur économique très importante pour les industries pharmaceutique, alimentaire, aromatisante et cosmétique. Keywords : Lavandula, Algérie, utilisation traditionnelle, activités biologiques.

The genus Lavandula : a promising pharmacological power
The Mediterranean region is characterized by a diverse vegetation cover, and the Lavandula genus is one of the most important medicinal and aromatic plants in this region. The genus Lavandula is composed of approximately 40 species, many hybrids, and nearly 400 registered cultivars. The best-known and most economically valuable species are L. angustifolia, L. stoechas, L. latifolia and the L. x intermedia hybrid. The Lavandula species are sub-shrubs or sometimes perennial shrubs up to one meter in height and grow in rocky and calcareous areas. Plants of the genus Lavandula are traditionally believed to be antibacterial, anti-fungal, carminative, sedative, anti-depressive, and effective for burns and insect bites. They were also prescribed for the treatment of epilepsy and migraine attacks. Phytochemical research has shown that the genus Lavandula contains a variety of secondary metabolites, mainly monoterpenes and sesquiterpenes found in essential oils. The main constituents of these essential oils are linalol, linalyle acetate, 1,8-cineole, camphor, β-ocimene and terpinen-4-ol. According to recent research, the essential oils of Lavandula species are effective in food conservation and insect control. The medical and pharmacological qualities of Lavandula plants are mainly due to its essential oils, in particular the main constituents of essential oils, although some activities have been attributed to phenolic compounds. Lavender oil is used in a variety of medicinal applications; it is considered an oral antispasmodic, soporific agent, anxiolytic agent, chemotherapeutic agent, topical antibiotic, and a treatment for alopecia. Keywords: Lavandula, medicinal uses, essential oils, biological activities.
