Abstract

The objective of this study was to analyze the fatty acid content, antioxidant, and antimicrobial activities of Argemone mexicana seed oil growing wild in north East Ethiopia. Oils of A mexicana L. were obtained by means of Screw press from seeds. Methyl esters were derived from the oily mixtures by trans-esterification process and were analyzed by GC/FID and GC/MS systems. This oil was investigated for antioxidant activity using a DPPH radical-scavenging assay and was also tested against a panel of microorganisms. Linolenic acid (49.00%) and oleic acid (28.91%) were the most abundant fatty acids in leaves and stems, respectively. The oil showed moderate to highest antimicrobial activity against Bacillus subtilis, Candida albicans, Shigella dysentery, Staphylococcus aureus, Pseudomonas aeroginosa, and Escherichia coli. The oil also demonstrated the highest antioxidant activity with the percentage of inhibition of 92.5% at a concentration of 1.5 mg/mL, and its IC50 and AAI were 22.4 µg/mL and 4.93 µg/mL, respectively. The results obtained from the present study indicated that the oil of A mexicana seed oil contained a high source of polyunsaturated fatty acids. These results also showed that the extracted oil from this plant has significant antimicrobial and antioxidant activities.

测定墨西哥刺五加籽油的脂肪酸组成和生物活性特性

本研究的目的是分析生长在埃塞俄比亚东北部的野生 Argemone mexicana 种子油的脂肪酸含量、抗氧化性和抗菌活性。通过螺旋压榨法从种子中获得墨西哥刺芹籽油。通过反酯化工艺从油性混合物中提取出甲酯，并通过 GC/FID 和 GC/MS 系统进行分析。使用 DPPH 自由基清除试验对这种油的抗氧化活性进行了研究，同时还对一组微生物进行了测试。亚麻酸（49.00%）和油酸（28.91%）分别是叶和茎中含量最高的脂肪酸。这种油对枯草芽孢杆菌、白色念珠菌、痢疾志贺氏菌、金黄色葡萄球菌、绿脓杆菌和大肠杆菌具有中等至最高的抗菌活性。该油还表现出最高的抗氧化活性，在 1.5 毫克/毫升的浓度下，抑制率为 92.5%，其 IC50 和 AAI 分别为 22.4 微克/毫升和 4.93 微克/毫升。本研究得出的结果表明，A mexicana 种子油含有大量的多不饱和脂肪酸。这些结果还表明，从这种植物中提取的油具有显著的抗菌和抗氧化活性。
