Phytochemical screening, FT-IR and GC-MS analysis of Euphorbia hirta

Abstract

The aim of present study is to identify the phytochemicals present in the plant Euphorbia hirta and to subject the plant extracts for FTIR and GCMS analysis. Preliminary phytochemical screening of the methanol extract of the plant showed the presence of flavonoids, alkaloids, saponins, tannins, proteins, carbohydrates, Quinone’s, fats and oils. The FTIR spectroscopy of the chloroform, butanol and ethyl acetate extracts indicated the presence of OH, CH stretching saturated, C=O, C=C, NO2, C-N, Ar-O, C-O, R-O- C-Cl stretching respectively. Phytoconstituents in the methanol extract of E. hirta was studied using GC-MS analysis. Fifteen compounds were identified from the methanol extract. The main chemical constituent is glycol aldehyde dimer [Peak area: 41.22%; RT: 3.035; Mol. formula: C4H8O4].
