| Abstract: | The tea of Lycium barbarum L.leave was digested with HNO3,and the nine microelements(Na,Ca,K,Mg,Pb,Zn,Cu,Mn,Fe)in Lycium barbarum L.leave were determined by microwave digestion-AAS,which offer scientific data of treatment of cardiovascular and cerebrovascular diseases of Lycium barbarum L.leave from the perspective of trace elements.The results showed that the recovery(n=6)is 94.44%~101.98%(r=0.999 2~0.999 9),and the RSD(n=6)is 0.72%~3.93%.The method has good precision and sensitivity. |
