Investigation of phytochemicals in methanolic leaves extracts of Abutilon pannosum and Grewia tenax by Q-TOF LC/MS

The current study was carried out on the extraction, isolation, and identification of phytochemical constituents existing in the Abutilon pannosum and Grewia tenax leaves extract collected from Kachchh region of Gujarat state, India. The main aim of this study was to expose important polar phytochemicals in locally available medicinal plants using LC-Q-TOF-MS analytical techniques. The main analytical tool is liquid chromatography quadrupole time of flight mass spectrometry (LC-Q-TOF-MS) which is one of the most sophisticated and sensitive instruments that gives qualitative as well as quantitative information accurately with respect to constituents present in the sample. The continuous extraction of plant leaves was commenced by Soxhlet extractor utilizing methanol as a solvent. The crude methanolic extracts were inserted in LC-Q-TOF-MS for identification and isolation of useful phytochemicals. The results of phytochemical analysis displayed that there were significant phytochemicals found in methanol extracts of A. pannosum leaves (APL) such as alkaloids, photoproteins, antibioticand in G. tenax leaves (GTL) like alkaloids, photoproteins, glycoside, terpenoids, fatty amides, steroids, fatty alcohols, saponins, flavones, flavonols, steroid etc. Hence, methanolic extract of GTL gives good medicinal activity as compared to the APL.
