Assessment of some oligo-elements and heavy metals in different parts of the thymus broussonettii growing in Morocco

In order to valorize natural substances,inductively coupled plasma atomic emission spectroscopy (icp-aes) is employed for the determination of essential and nonessential elements in different parts (leaves,woods,and flowers) of thymus broussonettii medicinal plants largely used in morocco generally as remedies. this endemic was analyzed for ca,k,na,mg,fe,mn,zn,cu,co,cr,mo,se,si,b,ni and pb. principal component analysis was performed to provide a data structure study.
