Extraction methods, qualitative and quantitative techniques for screening of phytochemicals from plants

Abstract

Phytochemicals are secondary metabolites which have different health benefits and with respect to plants, they possess color, aroma and flavor. There are different extraction methods of phytochemicals which have been used from the past and which are novel. Those novel techniques are very efficient and they will enable to extract large yields from small amount of plant material. Further, there are some techniques which can be used for both qualitative and quantitative measurements. Gas chromatography, liquid chromatography, high performance liquid chromatography and high performance thin layer chromatographyare some advanced techniques which can be used for quantitative analysis of phytochemicals. The aim of this study is to elaborate different extraction methods and different qualitative and quantitative techniques for screening phytochemicals from plant materials.
