Abstract
Flavonoids are the secondary plant metabolites with diversities of pharmacological activities like antioxidant, anticancer, anti-inflammatory, hepatoprotective, free radical scavenging activity and antiviral activities. Flavonoids have also been proved as a major contributor to the antimicrobial phytochemicals. Being the major substituent of antibiotics today flavonoids has attained high attention as there is increase in persistence of untreatable microbial infections due to microbial resistance. This review demonstrates the screening, isolation of extracts and derivatisation of various flavonoids and their evaluation for antimicrobial potency. Recent advancements of various derivatives of flavonoids having antimicrobial activity has also been discussed in this review. This review helps researchers to get vast knowledge about flavonoids and also give an idea for current scenario of flavonoids and its applications as antimicrobial agent.
