Determination of Heavy Metals in Fufang Longxuejie Capsule by Atomic Absorption Spectrophotometry
Objective:Determination of the heavy metals elements in Fufang Longxuejie Capsule.Methods:The heavy metals elements(Pb,Cd,Cu,As,Hg)in Fufang Longxuejie Capsule were determined by atomic absorption spectrophotometry(AAS).The contents of heavy metals in Fufang Longxuejie Capsule from three different batches were determined by standard curve.Results:The contents of Pb,Cd,Cu,As were 0.23,0.32,0.51 mg/kg;0.05,0.08,0.06 mg/kg;0.05,0.04,0.04 mg/kg;0.26,0.58,0.40 mg/kg;0.01,0.02,0.03 mg/kg,and no Hg contents were determined.Conclusion:The contents of heavy metals elements(Pb,Cd,Cu,As and Hg)in the Fufang Longxuejie Capsule are all in line with the requirements of the 2020 edition of the Chinese Pharmacopoeia,and the Fufang Longxuejie Capsule has a good safety profile.
