Isolation and identification of Bioactive molecules from medicinal plants

Abstract

The present work describes the isolation and identification o f the chemical constituents o f two medicinal plants Euonymus hamiltonianus Wall Family Celastraceae and Lespedeza juncea Pers Family Fabaceae Phytochemical investigation of these two plants leads to the isolation and characterization of fourteen compounds The first part includes the experimental working of Euonymus hamiltonianus Wall The fresh aerial parts of Euonymus hamiltonianus Wall were extracted with hexane ethylacetate and subsequently with methanol After removal of solvent by distillation under vacuum methanolic extract was dissolved in minimum quantity of solvent and silica gel was added to form slurry By usual chromatographic techniques o f newlineisolation three pure constituents were ultimately obtained and characterized through detailed spectral studies
