GC-MS ANALYSIS OF METHANOL EXTRACTS OF Phragmanthera incana LEAVES FROM GUAVA, MANGO, CASHEW AND KOLANUT TREES

Abstract

Phragmanthera incana (Schum), a specie of mistletoe, belonging to the family Loranthaceae, is a hemi-parasitic plant growing on trees in South-Western part of Nigeria. The chemical composition of P. incana leaves have not been published in literature. Therefore, the chemical constituents of methanol extracts of P. incana leaves hemi-parasitized on Psidium guajava (guava), Cola acuminata (kolanut), Anacardium occidentale (cashew) and Mangifera indica (mango) were analysed using Gas Chromatography-Mass Spectrometry while matching compounds identified with National Institute of Standard and Technology (NIST) library. The GC-MS analysis revealed that P. incana from guava contained 38 bioactive Compounds, P. incana from cashew contained 41 bioactive compounds, P. incana from mango contained 43 bioactive compounds and P. incana from kolanut contained 50 compounds. The chemical constituents detected suggest and also validate the ethnomedicinal claims of the plants as all heals in that, it is rich in diverse compounds of know therapeutic and medicinal activities. Many of the identified constituents has various industrial and medical applications like flavour, antioxidants, anti-inflammatory, hypocholesteremic, hepatoprotective and cancer preventive activities.
