QUERCETIN, ENCAPSULATED QUERCETIN AND ITS APPLICATION- A REVIEW

Flavonoids are plant secondary metabolite shows a wide range of pharmacological and biological functions. Among the flavonoids, quercetin gained special attention for its potential therapeutic activities. The aim of this work was to summarize the medicinal property of quercetin, role of quercetin in synthesizing the silver and gold nanoparticles, pros and cons of quercetin, nanoencapsulation of quercetin and its advantages. This review article summarizes the published experimental research and scientific literature from the databases including PubMed, Google and local library searches. The results of these studies provide a complete understanding of the biological action of quercetin. Pharmaceutical effects of quercetin such as anti-oxidant, anti-inflammatory, anti-cancer, anti-toxic and immunomodulatory effects prove that quercetin has potential therapeutic value, though it has several beneficial effects on human health, it possesses some disadvantages like poor solubility, low bioavailability, the hydrophobic nature and poor permeability. To overcome the disadvantages of quercetin, it is encapsulated in the polymers to enhance its bioavailability and to increase its solubility. In this paper, a brief description about the encapsulation of quercetin and its application were focused.
