摘要
碘缺乏症(ID)是人类从膳食中摄入碘不足的结果,碘缺乏症不仅会导致甲状腺肿的形成,还会严重阻碍几乎所有人体组织的生长、发育和成熟,尤其是那些发育较快的组织。本研究的目的是利用铜络合物评估尼日利亚十种蔬菜的碘摄入水平。测定中使用了干碱灰分法。结果表明,当接种 0.09 M 和 0.14 M [Cu(I)4]2- 时,所有十种蔬菜都吸收了高浓度的碘。当接种 0.2-0.8 M 的络合铜时,所有植物都出现了碘植物毒性,因为所有植物都死亡了。络合铜浓度从 0.09 到 0.14 兆帕时,杂交马齿苋(Amaranthus hybridus)、鹅掌楸(Corchorous olitoruis)、荷包牡丹(Gongronema lotifolium)和茄科植物(Solanum melongena)对碘的吸收增加。而鹅掌楸、金丝桃、三棱草、鹅掌楸、葫芦科植物和西洋接骨木对碘的吸收则相反。 莴苣在 0.09M 浓度下的碘吸收率为 164.79 毫克/千克,在 0.14M 浓度下的碘吸收率最低,为 61.80 毫克/千克。植物对碘的吸收情况表明,该方法可用于尼日利亚蔬菜的碘强化,从而降低人类碘缺乏病的发病率。
Iodine Fortification Study of Some Common Nigerian Vegetables Using Copper Complex
Iodine deficiency (ID) is the result of insufficient dietary iodine intake in humans, the deficiency not only leads to goiter formation but also to severe retardation of growth, development and maturation of nearly all the tissues of the body, especially those that are fast developing. The aim of this research is to evaluate levels of iodine intake by ten Nigerian vegetables using copper complex. Dry alkaline ash method was used in the determination. The results obtained showed that all the ten vegetables used absorbed high concentrations of iodine when inoculated with 0.09 M and 0.14 M [Cu(I)4]2- . Iodine phytotoxicity was observed in all the plants when inoculated with 0.2-0.8 M of the copper complex as all the plants died. Increase in the concentration of copper complex from 0.09-0.14 M increased the absorption of iodine by Amaranthus hybridus, Corchorous olitoruis, Gongronema lotifolium and Solanum melongena. The reverse was observed with Murraya koenigii, Ocimum gratissimum, Talinium triangulare, Abelmoschus esculentus, Cucurbita pepo and Telfairia occidentalis. Ocimum gratissimum absorbed the iodine at 0.09M with value of 164.79 mg/kg, the vegetable also absorbed least at 0.14 M with a dose of 61.80 mg/kg. The intake of the iodine by the plants showed that the method can be used in the fortifying these Nigerian vegetables with iodine, thereby reducing the incidence of Iodine deficiency disorder in humans.
