Abstract: 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..
