Abstract:
Fruits, plants, vegetables, tea, bark, bulbs, stem, roots and wine all contain a class of natural compounds called flavonoids. Polyphenolic chemicals is also found in the blooms of Smith's Rhododendron arboreum. There have been numerous attempts to segregate these natural compounds, which are valued for their positive effects on health. Today, flavonoids are recognised as a crucial ingredient in a variety of cosmetic, pharmacological, and therapeutic compositions. The primary polyphenolic flavonoid, quercetin is widely distributed among plants is frequently present in foods and consumed on a daily basis, especially fruits and vegetables. Quercetin has long been used to treat a various conditions, including arthritis, cardiovascular diseases, cancer, eye and viral infections. It has been tested pharmacologically against a variety of microbes and parasites, including viruses and dangerous bacteria. Due to its inhibitory impact against acetylcholinesterase, it has also demonstrated therapeutic effects against Alzheimer's disease (AD). Additionally, it has been shown to have antioxidant, anti-fungal, anti-carcinogenic, and cardioprotective properties. According to research, quercetin is excreted by the respiratory, renal, and faecal systems and amasses in the liver, lungs, small intestine and kidneys with lower quantities in the spleen, heart and brain.
