Determination on Trace elements in 10 Kinds of Routine Vegetables

[Objective] The study was to provide the reference for guiding human diet.[Method] The contents of Ca,Mg,Mn,Zn etc 6 kinds of trace elements in 10 kinds of routine vegetables(eggplant,chrysanthemum coronarium,celery,carrot,summer squash,potato,cucumber,snap bean,tomato and green pepper) were determined by atomic absorption spectrometry.[Result] Ca content in 10 kinds of routine vegetables from big to small in order was chrysanthemum coronariumcelerysummer squashcucumbercarrottomatosnap beaneggplantgreen pepperpotato,Mg content in 10 kinds of routine vegetables from big to small in order was summer squash celery chrysanthemum coronarium snap bean cucumber green peppereggplantcarrot tomatopotato.The variation range of Cu,Fe,Mn,Zn in 10 kinds of routine vegetables were 8.188-2.505,38.00-294.00,6.95-115.50 and 26.39-84.88 μg/g resp.and the recoveries of trace elements were all from 92.5% to 103.6%.[Conclusion] There was great difference of trace element content in 10 kinds of routine vegetables.
