【摘要】 目的测定部分城乡成年居民血清中类胡萝卜素的浓度。方法从三个不同类型的社区中,选择184人30～60岁成人(男性84,女100)作为被调查对象,分别于夏、秋、冬、春四个季节时采集每个受试者的空腹静脉血,用HPLC测定血清中β-胡萝卜素、α-胡萝卜素、β-隐黄质、番茄红素、叶黄素类(叶黄素和玉米黄质)五种类胡萝卜素的含量。结果被调查者四个季节的血清中,五种类胡萝卜素的平均浓度(μmol/L)为:β-胡萝卜素0.72±0.20,0.71±0.18,0.70±0.19和0.63±0.20,α-胡萝卜素0.037±0.018,0.039±0.015,0.038±0.017和0.030±0.019,β-隐黄质0.11±0.03,0.14±0.03,0.13±0.04和0.10±0.03,叶黄素和玉米黄素0.61±0.16,0.45±0.09,0.46±0.12和0.47±0.14,番茄红素:0.43±0.26,0.11±0.06,0.07±0.04和0.07±0.03。春季时血清β-胡萝卜素明显低于其他三个季节,但其中城市中心社区居民的血清β-胡萝卜素浓度没有明显季节变化。血清α-胡萝卜素、β-隐黄质、叶黄素和玉米黄素、番茄红素浓度都有着显著的季节变化。三类居民间在每个季节、每一种类胡萝卜素成分的血清平均浓度都有显著差别。结论本文报告了184名中国成年居民夏、秋、冬、春四个季节713份血清中类胡萝卜素摄入量数据,为了解部分人群的血液类胡萝卜素分布提供资料。更多还原

【Abstract】 Objective The study was carried out to analyze serum carotenoids concentration of some Chinese adults by HPLC.Methods One hundred and eighty four 30 ～ 60 year-old adults(84 males and 100 females) from three different communities were recruited in the investigation.The fast blood samples were collected and separated into serum in summer,autumn,winter and spring of the year,respectively.The serum were extracted with organic solvents and analyzed with a HP1100 HPLC for the concentration of β-carotene,α-carotene,β-cryptoxanthin,lycopene,and lutein /zeaxanthin.Results The average serum concentration of carotenoids of investigated population in summer,autumn,winter and spring were as followed(inμmol /L),respectively:β-carotene,0.72 ± 0.20,0.71 ± 0.18,0.70 ± 0.19 and 0.63 ± 0.20;α-carotene,0.037 ± 0.018,0.039 ± 0.015,0.038 ± 0.017 and 0.030 ± 0.019;β-cryptoxanthin,0.11 ± 0.03,0.14 ± 0.03,0.13 ± 0.04 and 0.10 ± 0.03;lutein + zeaxanthin,0.61 ± 0.16,0.45 ± 0.09,0.46 ± 0.12 and 0.47 ± 0.14;lycopene,0.43 ± 0.26,0.11 ± 0.06,0.07 ± 0.04 and 0.07 ± 0.03.The average serum β-carotene concentration of total population was lowest in spring,but the descent did not occurred from urban sub-population.There were significant seasonal changes in average serum concentrations of αcarotene,β-cryptoxanthin,lutein + zeaxanthin,and lycopene from total population.Further more,there was significant difference of serum concentration of every carotenoid between three sub-populations in every season.Conclusions The data of serum carotenoid concentration in total 713 blood samples from some Chinese adults were reported here,which would be helpful to understanding the population distribution of carotenoid concentration in China.更多还原
