| Abstract: | Objective] The research aimed to determine the content of trace elements in longan seeds in Luzhou.Method] Longan seeds treated by wet decomposition with HNO3+ HClO4.Acetone was used in the content determination of 6 kinds of trace element including Ca,Fe,Zn,Ni,Mn,Cu in longan seeds by flame atomic absorption spectrometry.Result] The contents of Ca,Fe,Zn,Ni,Mn,Cu in longan seed were 4776.164,385.785,164.124,9.590,33.906,28.218 μg/g respectively.The relative standard deviation was from 1.6 to 3.9% and recovery was form 95.7% to 102.5%.Acetone has been proven to increase the determination of sensitivity.Conclusion] Longan seed contained abundant trace elements of Ca,Fe,Zn in indispensable to human body.Acetone involved in the determination of trace elements in longan seeds by flame atomic absorption spectrometry is simple and reliable. |
