Abstract

The plant Mentha piperita was widely used as a carminative, antiinflammatory, antispasmodic, antiemetic, and anti-catharrhal in traditional medicine, as well as to flavor chewing gum, ice cream, and pastries. The external application of mint oils has antibacterial, astringent, antiseptic, and antipruritic properties. The ethanol extract of the Leaves of Mentha Piperita was obtained by Soxhlet extraction method. In the phytochemical analysis of the ethanol extract of mentha piperita Leaves, imary and secondary metabolites like alkaloids, tannins, steroids, cardiac glycosides, proteins, carbohydrates, flavonoids, anthocyanins, anthraquinones, and saponins were found. Using ethanol as a solvent, the λmax (Absorption maxima) was measured at 660, 610, 525, 380, and 270 nm with the absorbance value of 2.319, 2.255, 2.354, 2.733and 1.910 respectively by using double beam UV-VIS spectrophotometer.

Keywords: Soxhlet apparatus, Secondary metabolites, UV-VIS spectra, ?max.
