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.
