Abstract
Evaluation of different plant species of Allium has resulted in identification of several bioactive constituents/phytochemicals. Some of the bioactive phytochemical constituents include organosulfur compounds, thiosulfinates, polysulfanes, polyphenols, tannins, flavonoids, alkaloids, saponins, fructans, fructo-oligosaccharides, essential oils, amino acids, vitamins, pigments, and much more. Traditionally, majority of the plants belonging to Allium sp. have been proved to be effective in treating flu, cold, cough, asthma, headache, stomachache, arthritis, and other common ailments. Besides, bioactive compounds identified in some of the commonly used Allium sp. plants are scientifically proven to contribute towards a wide range of bioactivities such as antioxidant, antimicrobial, anti-inflammatory, antidiabetic, anticancer, antihypercholesterolemic activities and much more.
