湖北恩施是爆发过世界上首例人群硒中毒的高硒背景区,蕴藏有丰富的富硒植物资源,调查发现了大量的富硒、超富集硒植物,具有很好的开发利用前景。利用高效液相色谱与电感耦合等离子体质谱联用仪(HPLCICP- MS)对恩施鱼塘坝硒矿区发育的醉鱼草(Buddleia lindleyana)、水芹菜(Oenanthe javanica)富硒植物进行了硒形态的分析研究。结果表明,醉鱼草和水芹菜总硒含量分别高达531.4和213.1μg·g~(-1),从中检测出硒代胱氨酸(Secys_2)、硒代蛋氨酸(SeMet)和无机硒Se(VI)3种形态硒,其中醉鱼草的3种形态硒含量分别为14.2、26.2和221.2μg·g~(-1),水芹菜的3种形态硒的含量分别为4.24、28.49和169.9μg·g~(-1)。说明这些富硒植物具有用于提取天然有机硒的重要开发利用价值。 |

The Yutangba Se-rich independent deposit is abundant in Se-enriched biological resources.The Se-enriched plants were collected in its natural seleniferous habitat and their Se distribution and speciation in all organs were tested using HPLC-ICP-MS.The highest Se accumulation of 531μg·g~(-1) was observed in Buddleia lindleyana based on total Se measurements.Speciation studies revealed that both B.lindleyanaand Oenanthe javanica have three predominant form of Se which were SeCys_2,SeMet and Se(VI)with concentration of 13.5,24.2,202.1and 4.2,25.4,158.6μg·g~(-1),respectively.The total selenium content was more than one hundred times compared with the artificial cultivation of Se-enriched products(Seenriched garlic,Se-rich rice and Se-enriched pumpkin seeds,etc.).This will spark interest in increasing and/or modifying the Se compounds in plants. |
