Abstract
Objective: The present study aim is to analyse the phytochemicals present in Grewia tilifolia (Vahl) leaf extracts by using Qualitative phytochemical analysis, Fourier-transform infrared spectroscopy (FTIR).
 Methods: The leaf extracts were prepared using eight different solvents. The phytochemical analysis Fourier transform infrared spectroscopy (FT-IR) analysis were performed using standard methods.
 Results: The FTIR spectroscopic studies revealed different characteristic peak values with various functional groups present in the compounds of respective extracts. The FT-IR analysis shows the presence of different functional groups such as alcohols, phenols, alkanes, carboxylic acids, aldehydes, ketones, alkenes, primary amines, aromatics, esters, ethers, alkyl halides and aliphatic amine compounds, which showed major compounds present in the leaf extracts. The present study generated the FTIR spectrum profile for the medicinally important plant Grewia tilifolia.
 Conclusion: The present study provides evediences that different extracts of Grewia tilifolia leaf is useful to cure many serious diseases which remained still problematic and for further isolation of bioactive compounds from the plant which could be of interest for the development of the new drug.
Highlights
Plants are a very useful source of various bioactive compounds which have direct or indirect use in the treatment of various human ailments [1]
The Fourier-transform infrared spectroscopy (FTIR) spectrum was used to identify the functional groups of the active components present in extract based on the peaks values in the region of IR radiation
When the extract was passed into the FTIR, the functional groups of the components were separated based on the ratio of its peak
Summary
Plants are a very useful source of various bioactive compounds which have direct or indirect use in the treatment of various human ailments [1]. A large number of medicinal plants are used as an alternative medicine for diseases of man and other animals since most of them are without side effects when compared with synthetic drugs. These are used as medicines to maintain their health care, consumed as food by several Tribes of the Indian subcontinent. Phytochemicals are responsible for medicinal activities of the plants [2]. Based on this fundamental knowledge several pharmaceutical industries are established. Spectroscopic methods are very rapid and cost-effective than other conventional methods
