| Abstract: | Objective: To explore the medicinal and food value of Trillium tschonoskii Maxim by investigating its microelement contents.Methods: The samples were treated by dry ashing method and then the contents of microelements were detected by using graphite furnace atomic absorption spectrometry.Results: Nine kinds of microelements evaluated in Trillium tschonoskii Maxim were: Zn(20.00 mg / kg),Fe(95.5 mg / kg),Cu(7.5 mg / kg),Mn(11.75 mg / kg),Cd(0.02 mg / kg),Cr(0.0955 mg / kg),Co(0.0075 mg / kg),Pb(0.01175 mg / kg),Ni(0.07275mg/kg).Conclusion: The results revealed that Trillium tschonoskii Maxim.is rich in essential microelements including Zn,Fe,and Mn,and low in harmful elements like Pb and Cd. |
