Effect of Extraction Methods and Solvent on Phytochemical Composition of Medicinal Plant Extracts

Author(s): Kannamba B, Winnie Teja D, Surekha M, Lavanya B

In the present study Tridax procumbens, Murraya koenigii and Pongamia pinnata leaves extracts of water, ethanol, methanol and acetone were prepared using ‘Green extraction’ methods such as microwave assisted and ultrasonic assisted solvent extraction. The extracts were screened for phytochemicals like alkaloids, phenolic compounds, flavonoids, tannins, terpenoids and diterpenoids. Further, phytochemical composition of microwave assisted extracts was compared with the ultrasonic assisted extracts. The results reveal that phytochemical composition of leaves extracts highly varied with the extraction method as well as solvent used for extraction. The present study may be useful to select an appropriate solvent and method for isolation of phytochemicals from T. procumbens, M. koenigii and P. pinnata leaves.
