Migration and degradation by volatile compounds from  scent leaf (ocimum gratissimum) on polyethylene terephthalate packaged water  was studied using dichloromethane for extraction(solvent extraction) of  the analyte from water packaged in polyethylene terephthalate. GC-MS was used to quantify the components.  A total of 24 compounds were identified and quantified in the experiment which included: 3 hydrocarbons, 1 polycyclic aromatic hydrocarbon, 5 alcohols, 2 ketones , 4 phthalate, 6 esters, and 3 organic acids.  The  amount of diisobutyl phthalate(2.20%) followed by  2- decanol (0.00992%),  triethyl citrate (0.0429%), hexanedioic acid (0.0264%),  4 – dodecene-6,8,10-triyn-one (0.00233%), squalene (0.0184%) and pyrene (0.0106%). Nitrogen was the only component  found in the control, since it was not stored  with the  scent leaf (ocimum gratissimum)  . The result showed that polyethylene terephthalate  are  degraded by volatiles from plants. Hence, bottled and sachet water should be stored separately in homes,offices laboratories etc.
