Determination and comparison of phytochemical in Sesamum laciniatum Klein ex Willd by using FTIR spectroscopy

Abstract

Sesamum belongs to Pedaliaceae, a small family of 17 genera and 80 species of annual and perennial herbs. The biologically active compounds present in plants are called phytochemicals. These phytochemicals are derived from various parts of plants such as leaves, stem and roots. These phytochemicals are used as sources of direct medicinal agents. They serve as a raw material base for elaboration of more complex semi-synthetic chemical compounds. The extraction of active compounds from the various parts of plants, qualitative and FTIR spectroscopic analysis of the phytochemicals. The wavelength of many IR absorption bands are characteristics of specific types of chemical bonds and IR spectroscopy finds its greatest utility for qualitative analysis of organic and organometallic molecules. IR spectroscopy is used to confirm the identity of a particular compound and as a tool to determine the newly synthesized molecule.
