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 [1]. 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. [9] 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 [13]. 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].
