MAZIMBA, O.; MASESANE, I.B.; MAJINDA, R.R.T.  and  MUZILA, A.. GC-MS analysis and antimicrobial activities of the non-polar extracts of Mundulea sericea. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp.50-52. ISSN 1996-840X.

The composition of the non-polar extracts of the leaves, stem bark and twigs of Mundulea sericea (Fabaceae) were analyzed using GC-MS. Eight, five and eleven components were identified from the leaves, twigs and stem bark extract, respectively. The major components were identified as: caryophyllene (43.6 %) and cadina-3,9-diene (29.7 %) in the leaf extract, amorphene (34.4 %) and valencene (17.9 %) in the stem bark extract and isoledene (29.0 %) and α-gurjunene (22.4 %) from the twig extract. Sesquiterpenes were the major abundant components in the non-polar extracts. The leaf, stem bark and twig extracts showed weak antibacterial and antifungal activities.

Keywords : Mundulea sericea; GC-MS; non-polar; sesquiterpenes; antimicrobial.
