Gc-ms analysis of bioactive constituents of magnolia nilagirica (zenkar) figlar. (magnoliaceae)an endemic medicinal plant to the western ghats, India

The present study was carried out to determine the possible bioactive components of methanolic leaf extract of Magnolia nilagirica by using GC-MS analysis. The GC-MS analysis provides different peaks determining the presence of 55 compounds were identified from the leaf extract of M. nilagirica. The main compounds in the plant extract were identified as 1Butanol, 3 – Methyl (13.25 %), 2H-Cyclohepta[b]furan-2-one (11.11 %), 5-O-Methyl-d-gluconic acid dimethylam (7.50%), Xanthanin (3.94%), 3.alpha.,6.alpha.-Dihydroxy-5.beta.-preAllopregnane-7.alpha.,11.alpha.-diol-3 (3.47%) and 2,5-Anhydro-1,6-Dideoxyhexo (3.29 %), 1,3-Cyclohexadiene (3.04%) 2,3-Dihydro-5-Hydroxy-6-Met4H-Pyran-4-one, 2,3-dihydro-3,5-dihyd (3.04%). The presence of various bioactivecompounds confirms the application of M. nilagirica for various ailments by traditional practitioners. However, the isolation of individual phytochemical constituents may proceed to find a noval drug.
