火焰原子吸收光谱法对橄榄各器官微量元素含量的测定

用火焰原子吸收光谱法分析了6个橄榄品种各器官的Fe、Mn、Cu、Zn、Ni、Cr含量。结果表明:除Ni在种子中未检出外,所测6个元素在橄榄新叶、老叶、茎、果肉、种子、果核、根等器官中均有一定的分布;各微量元素在不同器官、不同植株以及不同品种之间存在一定的差异。所测橄榄品种各器官中的Fe、Mn、Cu、Zn、Ni的含量在一般植物体的正常含量范围之内,但Cr含量远远超出正常含量范围,表明橄榄是一种富集Cr植物;由于生物体的有机铬是有效的抗癌和降脂成分,因此橄榄超高含量的Cr可能与橄榄抗癌和去脂减肥药用作用密切相关。

The measurement of the Contents of the Trace Elements of the Organs by the Method of Flame AtomicAbsorption Spectrometry(FAAS) in Canarium album Raeusch

The contents of Fe, Mn, Cu, Zn, Ni and Cr of the organs were measured by the method of Flame Atomic Absorption Spectrometry (FAAS) in 6 cultivars of Canarium album Raeusch. The results showed that,except for Ni in the seed, six trace elements existed in all the organs, including the young leaf, old leaf, stem, flesh, seed, stone and root, but the contents of these trace elements differed to some extent among different organs, trees or cultivars. The contents of Fe, Mn, Cu, Zn and Ni of all the organs in Canarium album Raeusch. belonged to the normal contents of the trace elements in plants, but the content of the Cr was far higher than that of the general plants, which suggested that Canarium album Raeusch. be of Cr hypertolerant plant. Because organic Cr in organisms was the effective element with the effects of anti-cancer anticancer and fat reducing, the ultrahigh content of Cr was probably related to the effects of anti-cancer anticancer and fat reducing of Canarium album Raeusch.
