ISOLATION AND IDENTIFICATION OF PHENOLIC COMPOUNDS FROM LEAF EXTRACTS OF COCHLOSPERMUM RELIGIOSUM (L.) ALSTON BY ELECTROSPRAY IONIZATION MASS SPECTROMETRY

Article history The present study intended to isolate phenolic compounds from the leaf of Cochlospermum religiosum by using 70% acetone and poly vinyl pyrrolidane; and characterized by UV-visible spectrometry, high performance liquid chromatography/ electrospray ionization mass spectrometry. The results showed that totally 87 phenolic compounds were obtained at both positive and negative ion modes of LCMS. Among the isolated phenols, 11 phenolic compounds have been identified based on their retention time and m/z values namely, Gallic acid, 2,3-Dihydroxybenzoic acid, Ascorbic acid, Quercetin, Cynarine, 1,2,3,4,6-Pentagalloyl glucose, Syringaldehyde, Thymol, Ellagic acid, Isorhamnetin and Benzoic acid. This study illustrates the rich array of phenolic compounds of leaves of Cochlospermum religiosum could be utility as health beneficial bioactive compounds.
