Antimicrobial Activity Test of Genus Allium: A Review

Abstract

The genus Allium plants are often used by people as a food flavoring. These plants are also used for medicinal purposes. The genus Allium plants are known to inhibit the growth of microorganisms such as bacteria, fungi, viruses, and parasites by having the Allicin, Ajoene main compounds, and secondary metabolites. This review article describes plants from the genus Allium that have antimicrobial potential. In the writing process, this review article used literature study techniques by finding literature in the form of official books, national journals, and international journals in the last 10 years (2010-2020). The literature search in writing this review article was conducted through online media search with keywords as follows: antimicrobial, Allium, and inhibition zone diameter. The search for the main references in this review article was done through Google Scholar, ScienceDirect, Reserachgate, and other published journals. Some plants of the genus Allium such as Allium ascalonicum, Allium cepa, Allium chinense, Allium porrum, Allium roseum, Allium sativum, Allium staticiforme, Allium subhirsutum, Allium tuberosum, Allium tuncelianum, and Allium wallichii showed antimicrobial activity. The potential antimicrobial activity of each part of the plant depends on the solvent used, the concentration and levels of secondary metabolites contained therein.

Ethnomedicinal and traditional application of Allium wallichii Kunth (Himalayan Onion): An unexplored and underutilized nutraceutical plant foods from Himalayan regions.

“…Progressively, 7 mg/ ml concentration of aqueous, ethanol and methanol extract of bulb was found to inhibit Bacillus pumilus, Candida albicans, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa significantly in another study. Further higher antioxidant activity was shown by water extract (IC50 = 1.21 µgmL -1 ) when compare with ethanol extract (IC50 = 2.10 µgmL -1 ) via DPPH method (Yee 2019, Arifa et al 2020. In another study presence of spatially structured unique useful microbiome to differentiate from other plant sources has been investigated.…”

Stomatal Analysis of <i>Allium wallichii</i> Kunth Leaves: An Experimental Finding through Quantitative Microscopy

“…The plant was also revealed to contain carbohydrates, proteins fibre, fat, Ca, Cu, Fe, K, Mn, Rb, S, Si, Zn and vitamin C [31][32][33] . Pharmacologically plants have been studied for antimicrobial, anticancer, antioxidant and anti-inflammatory activities 11,27,28,32,[34][35][36][37][38] . For a long, the plant is very useful and highly neglected during current research.…”
