    COMPOSITION, ANTIBACTERIAL AND ANTIOXIDANT ACTIVITIES OF ARTEMISIA HERBA-ALBA ESSENTIAL OILS FROM ALGERIA
    (university of el oued/جامعة الوادي, 2018-09-01) Dahmani-Hamzaoui, N; Sabaou3, N; Salido, s; Altarejos, J; Baaliouamer, A
    The essential oils of three individual plants of Artemisia herba-alba, growing wild in tree different locations from Bordj Bou Arrérridj in East Algeria has been extracted by hydrodistillation and a microwave distillation process. The main components were α-thujone (35.1 and 31.2% in HD and MD oils, respectively) for Draâ Ech, davanone (39.6-37.3%) and 1, 8-cineole (9.2-7.8%) for Bordj Ghédir, chrysanthenone (29.6-43.8%), camphor (18.6-16.0%), and α-thujone (15.9-8.6%) for Bordj Bou Arrérridj. In comparison with HD, MD allows to obtain oil in a very short time, with the comparable qualities and substantial saving of energy. The minimum inhibitory concentration of various essential oils shows a power inhibitor not exceeding 10 µg/mL against all microbial strains. The three chemotypes were slightly active, and the weak DPPH radical scavenging activity of these oils could be attributed to the absence of some phenolic components.

    MONITORING THE MATURITY OF AHMEUR BOUAMER AUTOCHTONOUS VARIETY AND DETERMINING OF THE OPTIMUM HARVEST DATE
    (university of eloued -جامعة الوادي, 2022-01-01) Ghouila, Z; Baaliouamer, A
    Morphological ampelography characteristics, technological, phenolic and tannic maturities were studied over four seasons (from 2009 to 2012) of Ahmeur Bouamer autochtonous Algerian variety. During the four harvests, Ahmeur Bouamer's cluster has showed a high quality of morphological parameters (weight, size, number of seeds/ berries per cluster).The weight was proportional to the size of the cluster which was moderately compact, thus avoiding the deformation and the bursting of the berries. As For the maturity index (MI), Ahmeur Bouamer grape recorded values ranging from 31.07 to 54.95 for the four seasons; values which would make it possible to consider that the harvest would be of excellent quality (when 30
