Nutritional and Bioactive Compounds, Antioxidant Properties and Antibacterial Activity of Chinese Chive (Allium odorum L.).

The present study was conducted to generate the comprehensive data on the nutritional composition, minerals, heavy metal, bioactive compounds, antioxidant and antibacterial properties of Chinese chive (Allium odorum L.) grown at two different locations including Manipur and Punjab. The crop grown in Manipur exhibited higher values of nutritional and phytochemical compound values than those grown in Punjab. It exhibited significantly higher amounts of crude protein, crude fiber, potassium, calcium and iron content in the Manipur environment. The allicin content in leaves of Chinese chive on a dry weight (dw) varied from 1.31 to 1.4% and there was non-significant difference in allicin content at both locations. Besides, the heavy metal content of Chinese chive was much below the permissible limits of the World Health Organization. The IC₅₀ value of Chinese chive was 78.908-95.140 µg/ml which imparts strong antioxidant activity and higher DPPH (2,2-diphenyl-1-picrylhydrazyl)radical scavenging activity higher in fresh leaves than dried leaves. Total phenol and total flavonoid were found to be significantly high. In addition, high antibacterial activities were observed against toxin producing pathogenic bacterial strains of Staphylococcus aureus and Enterococcus faecalis. The nutritional and bioactive compounds, antioxidant properties and antibacterial activity of Chinese chive make it ideal for its use as a functional food and/or supplement.
