Abstract

Objective: Objective: To investigate the contents of Pb,Cd and Cu in Cistanche deserticola Y.C.Ma from Xinjiang.Methods:The dry Cistanche deserticola Y.C.Ma power was directly reduced by wet method and dissolved with the digestive juice(HNO3 ∶HClO4=4 ∶1)were directly measured by using the FASS The Pb,Cd and Cu in it.Results:Three origin contain a certain amount of Cistanche deserticola Y.C.Ma of heavy metal,But all not exceeds limit range.The recovers of Pb,Cd and Cu were 97.65%,102.5% and 97.61%,RSD were 9.0%,3.0% and 3.1%,respectively.Conclusion:The method is quick,simple and convenient for determination of heavy elements in Cistanche deserticola Y.C.Ma.
