The aim of the work was to compare a standard and a closed vessel microwave mineralization and to select an optimal method of botanical sample preparation for determining macro- and microelements. Studies were made using plant referrence materials and chosen real samples. The comparison was based upon the determination of contents of seven elements by AAS in flame. The results corroborate the average of the microwave over the classic mineralization method both for the total decomposition and for the digestion
