Six strawberry samples, commercially grown in Pakistan, were studied for physicochemical properties. All samples have high level of water and low contents of ash and volatile compounds. The berry was found to be a good source of potassium (1.14–1.93 g/kg), magnesium (0.12–0.15 g/kg), calcium (79.59–124.11 mg/kg) and sodium (23.51–36.03 mg/kg). The lead and cadmium contents were below the detection limits (1.0 ± 0.1 μg/l for lead and 0.1 ± 0.01 μg/l for cadmium). Principal component analysis and cluster analysis were found to be good statistical tools for the evaluation of the compositional variations with respect to geographical origin.
