Quercetin a flavonoid to be a member of a group of flavonols is universally consumed in the human diet and responsibly to give the color to various fruits and vegetables . Mainly occur in the form of glycosides, but their other derivative have been identified [2-5]. This paper presents some recent advances regarding quercetin structure, derivatives, sources and their medicinal benefits with their effective dosage [6-8].

It is a 3, 5, 7, 3, 4-pentahydroxyflavon having the five hydroxyl groups placed at five different positions.  The chemical structure and different derivatives of quercetin presents in different food sources such as, Mango, plums, cranberry, blueberry, chokeberry, Buckwheat, honey, beans, lettuce, chicory, onion in different amount. Quercetin 3-O-galactoside, Quercetin 3-O-glucoside, Quercetin 3-O-glucuronide, Quercetin 7-O-glucoside, Quercetin 3-O-diglucoside and Quercetin 3-methyl ether are some derivatives that have been discovered in different plants [10-12] (Table 1 & Figure 1).

Quercetin is one of the most abundant food based flavonoids present in various edible vegetables, fruit and wine . Quercetin contents present in different plants sources are categorized in different categories such as, vegetable, fruit, plant, herb, shrub, beverage and others [14-16]. The most prominent sources of quercetin is canned capers 180.76mg/100g (Table 2). It has different medicinal benefits against brain disorder, renal injury, cardiovascular diseases, blood pressure, cancer, bacterial activity, inflammation, diabetes mellitus, arthritis and asthma [17-19]. Medicinal benefits of quercetin with effective dose concentrations presented in Table 3 [20-22].

Quercetin generally exist in the edible plants and mostly used to manufacturing of traditional medicine to relieve some type of diseases [23-25]. In some recent studies quercetin exerts its biological properties in vivo. Overall, the best source of quercetin is canned carpers with 180.76mg/100g and followed by raw lovage leave with 170.01mg/100g [26-28].
