Abstract

To collect the different types of leaves in various places, wash collected leaves with distilled water and dried these leaves in various processes like under shade dry for 15 days, place oven (45 oC) for 1 hour. Grind well using the above-dried leaves, so these leaves are changed to powder form. Utilize these shaded dried leaves powder, to prepare extract with solvents like methanol, ethanol, hexane, carbon tetrachloride, petroleum ether, ethyl acetate, benzene, chloroform, and water in various methods like mechanical stirring, Soxhlet extracted, etc. Finally using extract to characterize the spectral (UV visible, FT-IR, 1H NMR, GC-MS). This review provides literature on spectral analysis of shaded dried leaves extracts from 2010 to the 2021 covered.Principal of UV-Visible Spectroscopy “species containing three types of electrons are bonding, anti-bonding, and non-bonding electrons. Bonding and (n-electrons) non-bonding electrons can absorb energy in the kind of visible or ultraviolet light to go to a higher energy (excited) state. These electrons are present in upper energetic anti-bonding molecular orbitals”. Vibrational Spectroscopy develops spectra from matter and infrared radiation collaboration through emission, reflection, or absorption.The principle of NMR spectra involves three steps 1. To attract nucleus by using stable (Bo) magnetic field 2. These spins weakly magnetic field, generally this field suggested to as an (RF) radio-frequency pulse. 3. Evaluation and recognition of the electromagnetic signals produced by the nuclei. NMR spectroscopy is mainly used for the determination of inorganic and organic molecules. GC-Mass Spectroscopy instrument is used in various organic compounds to identify spectra.
