GC-MS analysis of bioactive compounds in Psidium guajava leaves

Abstract

The bioactive components of Psidium guajava leaves have been evaluated using GC/MS. The chemical compositions of Psidium guajava leaves were investigated using Perkin-Elmer Gas Chromatography–Mass Spectrometry, while the mass spectra of the compounds found in the extract was matched by the National Institute of Standards and Technology (NIST) library. GC/MS analysis of ethanolic extract of Psidium guajava leaves revealed the existence of Alpha - bisabolol, 1, 2- Benzenedicarboxylic acid, buty, Hexadeca-2, 6, 10, 14-tetraen, Caryophyllene, Bis (2-ethylhexyl) phthalate, Nerolidol and Germacrene. The qualitative analysis of ethanolic and aqueous extract of Psidium guajava leaves showed that tannin, phlobatannins, saponin, flavonoids, steroids, terpenoids, triterpenoids, carbohydrate, polyphenol and glycoside present in both extract. The quantitative determination of Psidium guajava leaves contain Phenol (9.33 mg/gm powder), Tannin (4.30 mg/gm powder), Flavonoids (6.42 mg/gm powder) and Saponin (3.67 mg/gm powder). The results of this study offer a platform of using Psidium guajava leaves an herbal alternative for various diseases.
