ABSTRACT
Humans have been consuming plants and herbs for ages which are rich in phytonutrient compounds synthesized within these plants and herbs. Flavonoids are ubiquitous in the plant kingdom, having a characteristic flavan nuclei, giving rise to various functions, including UV protection, defense, auxin transport inhibition, allelopathy, and flower coloring. They are also responsible for various biological activities in plant, animal, and bacterial systems, and many groups have isolated and identified the structures of flavonoids possessing antifungal, antiviral, and antibacterial activity. Apart from this, the synergistic effects of flavonoids with existing chemotherapeutics are also evaluated. Hence, these compounds are becoming vital for nutraceutical, pharmaceutical, medicinal, cosmetic, and other applications.
