title: [The element determination of six samples of petal powders by using XRF spectrometry].
abstract: Elements and contents in three kinds of petal powders of white and red rose, carnation, and butterfly orchis were determined by using XRF technic, and the data for every group were compared and analysed. The results indicated that all powders contain no toxic elements determined but have lots of normal elements and trace elements, such as Fe, Cu, Zn, Mn, Ni, Si, Sr, and Rb. The same sort of powder had approximately equivalent elements but their contents are different, and the element content of the white sort. was higher than the red one.
