In this research, some plant seeds powder was evaluated to find their potential effect to rule diseases of food poisoning. Antimicrobial effect of five plant seeds was examined contra Bacillus cereus, Staphylococcus aureus, Escherichia coli, Klebsiella. pneumonia and Candida albicans by using well diffusion method. Antimicrobial activity studies revealed high potential activity of plant seeds powder of Nigella sativa L., cucurbita pepo, Sesamum radiatum, Trigonella foenum-graecum, Linum usitatissimum with variable efficiency contra tested microbial strains with concentration of 100 mg/ml, except Sesamum radiatum scored no effect. The T. foenum and N. sativa seed powder showed the largest inhibition zone (24-20 mm) contra K. pneumonia, followed by S. aureus (20-18 mm) and C. albicans (15mm) respectively. The five plant seeds powder exhibited bacteriostatic and bactericidal effects with MIC's 20 and MBC 40 mg/ml against K. pneumonia, and MIC's 40 and MBC 60 mg/ml against S. aureus. The results of this study indicated that plants seeds powder have promising antimicrobial activities and their potential applications in food process. It could be utilized as a natural medicinal alternative instead of chemical substance.
在这项研究中，评估了一些植物种子粉末，以发现它们对食物中毒疾病的潜在治疗效果。采用琼脂扩散法，研究了五种植物种子粉末对蜡状芽孢杆菌、金黄色葡萄球菌、大肠杆菌、肺炎克雷伯菌和白色念珠菌的抑菌作用。抑菌活性研究表明，黑种草、南瓜、芝麻、胡芦巴、亚麻籽等植物种子粉末具有较高的抑菌活性，在 100mg/ml 浓度下对测试的微生物菌株具有不同的抑菌效果，而芝麻种子粉末则没有效果。在对肺炎克雷伯菌的抑制作用方面，胡芦巴和黑种草种子粉末的抑菌圈最大（24-20mm），其次是金黄色葡萄球菌（20-18mm）和白色念珠菌（15mm）。五种植物种子粉末对肺炎克雷伯菌的 MIC 为 20mg/ml，MBC 为 40mg/ml；对金黄色葡萄球菌的 MIC 为 40mg/ml，MBC 为 60mg/ml，表现出抑菌和杀菌作用。本研究结果表明，植物种子粉末具有良好的抗菌活性，有望在食品加工中得到应用。它可以作为一种天然的药用替代品，替代化学物质。
