这项工作的目的是量化巴西人最常消费的食物中存在的黄酮类化合物。在所有被分析的蔬菜中发现的最丰富的黄酮类化合物主要是槲皮素的糖苷。在生菜中也检测到少量的木犀草素。在甜椒中，槲皮素和木犀草素都存在。总黄酮含量最高的是白洋葱[48-56 mg/100g鲜重(FW)]、红洋葱(40-100 mg/100g鲜重)、红生菜(67-67.2 mg/100g鲜重)、芝麻菜(41-118 mg/100g鲜重)和菊苣(18-38 mg/100g鲜重)。在果实中，柑橘果皮(125-170 mg/100g果肉)和果肉(35-44 mg/100g果肉)和某些苹果品种(14-36 mg/100g果肉)中类黄酮类化合物含量最高。叶类蔬菜和红葱的类黄酮类含量因采收时间的不同而变化较大。据估计，巴西人每天的摄入量在60到106毫克之间。
The objective of this work was to quantify the flavonoids present in foods most commonly consumed by the Brazilian population. The predominant flavonoids found in largest abundance in all of the analyzed vegetables were glycosides of quercetin. In lettuce, a small amount of luteolin was also detected. In sweet pepper, quercetin and luteolin were both present. White onion [48-56 mg/100 g of fresh weight (FW), expressed as aglycon], red onion (40-100 mg/100 g of FW), red lettuce (67-67.2 mg/100 g of FW), arugula (41-118 mg/100 g of FW), and chicory (18-38 mg/100 g of FW) were highest in total flavonoids. In fruits, the highest concentrations of flavonoids were found in the peel (125-170 mg/100 g of FW) and pulp (35-44 mg/100 g of FW) of oranges and in some apple varieties (14-36 mg/100 g of FW). Variability in flavonoid content due to time of harvesting was high for leafy vegetables and red onions. The estimated ingestion by Brazilian population ranged from 60 to 106 mg/day.
