Analysis of phytoconstituents and free radical scavenging activity of hydroethanol extract of Allium sativum bulb

Abstract

Background: Allium sativum, a traditional medicinal herb, is used as a natural drug in India since ancient time. In this article, the antioxidant and scavenging of free radicals by A. sativum bulb extract were evaluated. Materials and Methods: The hydroethanol extract of A. sativum powder was prepared by the successive Soxhlet extraction process, and further, quantitative phytochemical estimation and in vitro antioxidant ability were conducted. Results: The hydroethanol extract of A. sativum contains the maximum number of phytochemicals such as alkaloids, phenol, glycosides, carbohydrates, flavonoids, tannins, saponins, and terpenoids. The findings of in vitro antioxidant ability confirmed that hydroethanol extract possesses free radical scavenging and antioxidant ability. Conclusion: Based on the findings, the present article concludes that bulbs of A. sativum contain essential molecules of antioxidants that possess therapeutic property.
