Abstract

This study was conducted to evaluate the chemical composition and elemental analysis of ethyl acetate crude fraction of Urtica dioca. The result obtained shows that all bioactive constituents are present in this fraction of plant. The ethyl acetate fraction was screened which comprises flavonoid (1.88 mg/100 g), alkaloid (1.32 mg/100 g), phenol (0.09 mg/100 g), saponin (1.64 mg/100 g) and tannins (0.8 mg/100 g). Small amount of elements Na, k, Ca, Mg, Zn, Fe and P are also present in this fraction of plant.

 

Key words: Urtica dioca, Urticaceae, chemical composition.
