COMPARATIVE QUALITATIVE AND SPECTROSCOPIC EVALUATION OF PHYTOCHEMICALS IN MEDICINAL PLANTS

Abstract

The objective of this research was to analyze the phytochemical constituents and medicinal values of certain medicinal plants through qualitative, quantitative, and spectroscopic analysis. The aqueous extracts of selected medicinal plants that is Euphorbia milii, Matricaria chamomilla, Parthenium hysterophorus and Stevia rebaudiana, were obtained, and certain phytochemical constituents were determined qualitatively. Qualitative analysis indicated the existence of alkaloids, phenols, tannins, flavonoids, saponins, terpenes, sterols, and quinones in the plant extracts. Quantitative analysis emphasized variations in the concentration of phytochemicals in the selected plants. Further, UV–Visible spectroscopy was performed for identification and estimation of phytochemicals. FTIR spectroscopy was performed to determine functional groups in bioactive compounds. The results emphasize the significance of medicinal plants as natural sources of phytochemicals with antioxidative and therapeutic effects.
