摘 要：
[Objective] The aim was to determine contents of Ca,Fe,Mn,Zn,Pb,Cu,Cd,As,Cr in the roots of Caulis sinomenii.[Method] Zeeman-GFAAS was adopted to determine Pb,Cd,As,Cr contents and Flame-AAS was used to determine Ca,Fe,Mn,Zn and Cu.[Result] The average content of Ca in caulis root was 604.430 mg/kg,Fe was 191.489 mg/kg,Mn was 299.216 mg/kg,Zn was 18.590 mg/kg,Cr was 1.750 mg/kg;the content of Pb was less than 0.7 mg/kg,Cu was less than 8 mg/kg,Cd was less than 0.5 mg/kg,As was less than 0.5 mg/kg.[Conclusion] The content of heavy metals in caulis root was low,but microelements were abundant.Compared with rattan,the contents of Fe and Ca were higher,which has development value.
