Microbe is a microscopic living organism which is closely linked to human life. One of pathogenic microorganisms such as Staphylococcus aureu,. may cause diseases. Sulfure of several plants are bioactive as antimicrobial. The properties of sulfure in Allium cepa L leads to an assumption that it has antimicrobial properties. Therefore, this study involved the antimicrobial test. The determination steps of antimicrobial Allium cepa L extract consisted of the Allium cepa L extract preparation, microbial regeneration and antimicrobial test. The antibacterial determination were performed by paper disc method. Based on the research data, determination of antimicrobial Allium cepa L extract resulted in inhibition zone area showed that the extract owned antimicrobial property.

AbstractBackground: The extracts of Allium cepa are known for their medical use: antioxidant, antiinflammatory, antimicrobial, fibrinolytic and antiplatelet properties. Our study aims to establish, using in vitro tests, the antiplatelet and antioxidant character, the link between them and the extract acidity, from seven varieties of A. cepa. Methodology: The qualitative and quantitative presence of polyphenols and anthocyanins in the extracts was determined using UV-Vis and HPLC. Quantitative determination of the thiosulfinates compounds was calculated using their reaction with 4-mercaptopyridine. Antioxidant character was determined using 3 methods (FC, DPPH and TEAC), and antiplatelet effect was measured by in vitro tests on platelet rich plasma obtained from human blood. Principal Findings/Results: The white variety of A. cepa has the most alkaline pH, the largest amount of thiosulfinate compounds and the most powerful antiplatelet effect, but a very small amount of flavonoids and an antioxidant effect almost nonexistent, in contrast with red variety of A. cepa which is the opposite. Conclusions/Significance: The white variety of A. cepa had very high anitiplatelet activity suggesting the potential use of A. cepa extract in treating cardiovascular diseases.
