EVALUATION OF PHYTOCONSTITUENTS OF ERIGERON CANADENSIS L. BY FTIR AND GC-MS ANALYSIS

The Nilgiris District is one of the most botanized areas of Southern India. Asteraceae family is one of the largest families consisting of medicinal and aromatic plants in Nilgiris. The chemical compositions of Erigeron canadensis L. plant were investigated using Perkin-Elmer Gas Chromatography-Mass Spectrometry, while the mass spectra of the compounds found in the extract were matched by the National Institute of Standards and Technology (NIST) library. FT-IR and GC-MS analysis of ethanol extracts of Erigeron canadensis L. The shade-dried plant was powdered and subjected to selective sequential extraction using solvents of increasing polarity through percolation, for instance, using ethanol to obtain an ethanolic extract. Then, each of the extracts was further subjected to gas chromatography-mass spectrometry. GC-MS analysis of an ethanolic extract of Erigeron canadensis L. This revealed the existence of Methanethioamide, N,N-Dimethy (46.57%), N-Methylthio-acetamide (21.19%), Beta.-Sitosterol (7.80%), Disiloxane, Pentamethyl- (3.20%), Toluene P297 (3.18%), Benzene, 1,2-Dimethyl-(2.46%), Stigmasterol (2.40%),  Acetic Acid, Diethoxy-, Ethyl Ester (2.39%), Benzene, 1, 2-Dimethyl- (2.15%), Phytol (1.41%), 1-Heptatriacotanol (1.09%) and Lupeol (0.90%). These results indicate that the ethanol extract of whole plant of Erigeron canadensis L. GC-MS analysis revealed 23 essential bioactive compounds as well as the presence of antioxidant, anti-inflammatory, anticancer, antibacterial properties, enabling its recommendation as a plant of phytopharmaceutical importance.
