To analysis five kinds of heavy metalCu,PbCdAs and Hgcontent of Pogostemon cablin Benth. Of different regions caltived in Hainan island.Methods:The content of Cu,Pb and Cd is detected by Graphite Atomic Absorption Spectrophotometry.The content of As and Hg is detected by Atomic Fluorimetry.Results:The linear correlation coefficient of the content of Cu,PbCdAs and Hg is 0.9968-0.9998and the precision is less than 2.5%and the recovery is about 92.0%-98.7%. The content of Cu,PbCdAs and Hg of Pogostemon cablin Benth. Of WanningDongfang and Qionghai is 47.86.700.240.430.023 μg·g-127.47.200.300.790.134 μg·g-126.72.920.0530.6420.062 μg·g-1. Conclusion:The detection method of heavy metal content of Pogostemon cablin Benth. Of Hainan is established.The heavy metal content of Pogostemon cablin Benth. Of Hainan varies greatly in different regions of Hainan.
