摘要

本研究首次对阿尔及利亚奥雷斯山脉特有植物Ononis aurasiaca Förther & Podlech的化学成分和抗氧化、抗菌活性进行了研究。采用气相色谱-质谱法分析了植物地皮挥发油的成分。采用三种方法评价其体外抗氧化活性。共鉴定出44个化合物。主要成分为十二醛、六氢法尼丙酮、2-三十四酮、叶绿醇、1-烯二醇和正烯二醇。该油在β-胡萝卜素漂白试验中表现出显著的活性,对DPPH自由基的清除活性中等,对铁离子的还原能力较低。对4株菌株进行的抑菌试验显示,主要对革兰氏阳性菌株有效,特别是金黄色葡萄球菌ATCC 25923和ATCC 43300,而对革兰氏阴性菌株、铜绿假单胞菌ATCC 27853和大肠杆菌ATCC 25922的作用有限。两种霉菌的抗真菌活性试验表明,与黑曲霉相比,该霉菌对尖孢霉的抑制作用更强。

First report on the chemical composition and the free radical scavenging and antimicrobial activities of the essential oil of Ononis aurasiaca, an endemic plant of Algeria.

This study represents the first investigation of the chemical composition and the antioxidant and antimicrobial activities of Ononis aurasiaca Förther & Podlech, a plant species endemic to the Aures Mountains of Algeria. The essential oil of the plant aerial parts was analysed using GC-MS. The in vitro antioxidant activity was evaluated using three methods. A total of 44 compounds were identified. The major constituents were dodecanal, hexahydrofarnesylacetone, 2-tridecanone, phytol, 1-heneicosene, and n-heneicosane. The oil displayed significant activity in the β-carotene bleaching assay, moderate scavenging activity against DPPH radicals and a low ability to reduce iron ions. Antibacterial tests conducted on four strains revealed effectiveness primarily against Gram-positive strains, specifically Staphylococcus aureus ATCC 25923 and ATCC 43300, while showing limited impact on Gram-negative strains, Pseudomonas aeruginosa ATCC 27853 and Escherichia coli ATCC 25922. Antifungal activity tests involving two moulds revealed a stronger inhibition against Scedosporium apiospermum compared to Aspergillus niger.

期刊介绍: The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
