PHYTOCHEMICAL, FTIR AND NMR ANALYSIS OF CRUDE EXTRACT OF Pogostemon benghalensis LEAVES | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 


Pogostemon benghalensis belongs to the Lamiaceae family, commonly referred to as Hook loti, and is native to subtropical and tropical parts of India. It is commonly found in Melghat, where it originates under the shrub in the form of large patches along the banks of the river and is an annual, aromatic. Based on the polarity of the solvents, the leaves were extracted with chloroform, acetone, ethanol and water using the cold maceration method at around 15 °C. The presence of terpenoids and lactones in the acetone extract was shown in the sample through phytochemical screening of these extracts. Fourier Transform Infrared (FTIR) spectroscopy revealed the presence at 3373 cm-1 and 1708 cm-1 of different functional groups such as NH(amine), OH(carboxylic acid),=C=O(lactone), C-N(cyano)from the IR absorption bands in the high wave area and classified the active compounds by comparing the obtained compounds with the standard graph. Using H1 NMR (Nuclear magnetic resonance), the number of protons present and the electronic state of the protons in the different compounds were analysed. In order to isolate the active compounds that can be used to determine their therapeutic implications for the development of new drugs, further research should be carried out.
