dc.description.abstractالفعالية البيولوجية للزيت الأساسي للماد Cymbopogon schoenanthus L تهدف هذه الدراسة إلى التحقق من الفعالية المضادة للأكسدة و الفعالية ضد بكتيرية للزيت الأساسي لنبات اللماد النامي في الصحراء الجزائرية تم استخلاص الزيت الأساسي للجزء الخضري للماد عن طريق التقطير المائي (كليفنجر) لمدة 3 ساعات. أما الفعالية البكتيرية للزيت الأساسي للماد فاستعملنا طريقة الانتشار عبر الأقراص في وسط الجيلوز . السلالات البكتيرية المختبرة هي .Klebsiella pneumoniae ATCC 700603, Listeria innocua Clip74915, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Salmonella enterica ssp. Arizonae CIP 81, Staphylococcus aureus ATCC 25923, Bacillus cereus, Enterococcus faecalis الفعالية المضادة للأكسدة تم اختبارها عن طريق قدرة الزيت على كبح الجذر الحر للDPPH. نبات اللماد غني بالزيت الأساسي و الذي قدر مردوده بـ 6.06±0.54 % كما قدرت قيمة IC50 في الفعالة المضادة للأكسدة ب28.82±11.72 mg/ml لم يكن للزيت الأاسي تأثير واضح على السلالت البكتيرية Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Salmonella enterica ssp. Arizonae CIP 81, Bacillus cereus, Enterococcus faecalis،لكنه اضهر فعالية ضد Klebsiella pneumoniae, Listeria innocua, Staphylococcus aureus،و أعلى قطر تثبيط رسم عند السلالة Klebsiella pneumoniae,بـ 36.67±1.53mm. Bio-activity of essential oils from Cymbopogon schoenanthus L. This study aimed at investigating the Antioxidant and antibacterial activity of essential oils from Cymbopogon schoenanthus L. (spreng) was collected of south Algeria. The essential oils were extracted by hydrodistillation of fresh aerial part of C. schoenanthus a (Clevenger-type apparatus) for 3 h. The antimicrobial activity of C. schoenanthus essential oil was evaluated using Agar well-diffusion test (Lopes-Lutz et al., 2008). The microorganisms tested were Klebsiella pneumoniae ATCC 700603, Listeria innocua Clip74915, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Salmonella enterica ssp. Arizonae CIP 81, Staphylococcus aureus ATCC 25923, Bacillus cereus, Enterococcus faecalis. The antioxidant and free radical scavenging activity were determined by spectrophotome, Based on DPPH hydroxyl radical scavenging activity. The Cymbopogon schoenanthus was rich in essential oil, yielding (6,06±0,54%). Antioxidant activity essential oil has been done by using DPPH essay. IC50 values observed for DPPH essay were 28,82±11,72 mg/ml. The essential oil was not effective against Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Salmonella enterica ssp. Arizonae CIP 81, Bacillus cereus, Enterococcus faecalis. The essential oil of C. schoenanthus has an antibacterial effect against, Klebsiella pneumoniae, Listeria innocua, Staphylococcus aureus, the Highest inhibition was noted against Klebsiella pneumoniae (36,67±1,53mm).en_US
