Identification and characterization of diterpenes from ethyl acetate fraction of stem barks of Boswellia papyrifera (del) hochst, sudanese medicinal plant

In this study, the diterpen compounds present in the ethyl acetate fraction of stem bark of Boswellia papyrifera grown in Sudan were investigated using gas chromatography-mass spectrometry (GC-MS), based upon interpretation of the mass spectra fragmentation data, matching their mass spectra with NIST databases, and by comparison of the mass spectra obtained with those reference compounds published in literature.  A total of nine diterpenes were identified as m-camphorene 1, pimaradiene 2, verticilla-4(20),7,11-triene 3, serratol 4, incensole 5, incensyl acetate 6, duva-3,9,13-trien-1α-ol-5,8-oxide-1-acetate 7, incensole oxide 8, incensole oxide acetate 9 respectively. Among them compound 1, 2, 4 and 7 were reported here for the first time from this plant.
