采用反相高效液相色谱-紫外检测法测定了28种蔬菜和9种水果中可能具有抗癌活性的黄酮类化合物--栎素、山奈酚、杨梅素、芹菜素和木犀草素的含量。新鲜食品在超市、杂货店和街头市场购买，然后组合成复合材料。另外还购买了加工食品。在春季、夏季、冬季和次年春季进行采样。除洋葱(284-486毫克/公斤)、羽衣甘蓝(110毫克/公斤)、花椰菜(30毫克/公斤)、四季豆(32-45毫克/公斤)和豆片(28-30毫克/公斤)外，大多数蔬菜的可食用部分的槲皮素含量一般低于10毫克/公斤。山奈酚仅在羽衣甘蓝(211 mg/kg)、莴苣(15-91 mg/kg)、韭菜(11-56 mg/kg)和萝卜头(31-mg/kg)中检出。除不同苹果品种的含量为21~72 mg/kg外，大多数水果的平均含量为15 mg/kg。杨梅素、木犀草素和芹菜素的含量均低于检测限(
The content of the potentially anticarcinogenic flavonoids quercetin, kaempferol, myricetin, apigenin, and luteolin of 28 vegetables and 9 fruits was determined by RP-HPLC with UV detection. Fresh foods were purchased in a supermarket, a grocery, and a street market and combined to composites. Processed foods were purchased additionally. Sampling was carried out in spring, summer, winter, and spring of the following year. Quercetin levels in the edible parts of most vegetables were generally below 10 mg/kg except for onions (284-486 mg/kg), kale (110 mg/kg), broccoli (30 mg/kg), French beans (32-45 mg/kg), and slicing beans (28-30 mg/kg). Kaempferol could only be detected in kale (211 mg/kg), endive (15-91 mg/kg), leek (11-56 mg/kg), and turnip tops (31-64 mg/kg). In most fruits the quercetin content averaged 15 mg/kg, except for different apple varieties in which 21-72 mg/kg was found. The content of myricetin, luteolin, and apigenin was below the limit of detection (
