Phytochemical analysis and a review on biological importance of Allium cepa. L

Abstract

A biogenic substance may be a product created by or of life forms. The term encompasses constituents, secretions, and metabolites of plants or animals. In context of biological science, biogenic substances are cited as bio molecules. Onion (Allium cepa L.) has been valued as a food and a meditative plant since precedent days. It wide cultivated, second solely to tomato, and may be a vegetable bulb crop notable to most cultures and consumed worldwide. It’s a brief period agriculture crop grownup at low latitudes. It’s unremarkably called “Queen of the kitchen” due to its extremely valued flavor, aroma, and distinctive style. Recently, onion has drawn attention in many areas to its biological effects for human health. Besides well-known inhibitor activity due to the presence of radical scavenging property, consequently, there's increasing demand on the sensible technique to get such bioactive compounds from numerous plant supply. To utilize such valuable bioactive compounds within the plants, ways to isolate such substances from the source are required promptly. Therefore, identification of biologically active parts in onion plant by techniques like DPPH radical scavenging, total phenol content and total flavonoid tests are of great importance in medical and biological fields. Herein, we reported a review on biological importance of outer peel of onion and also identified biologically important components present in the sample.
