ABSTRACTObjective: The aim of this study was to investigate the presence of bioactive compounds in the methanolic leaf extract of Syzygium jambos.Methods: Collected leaves were shade dried and made into fine powder, extracted with methanol, and the methanolic extract was prepared andanalyzed for the presence of bioactive compounds by gas chromatography-mass spectrometry (GC-MS). The mass spectrum of the chromatographywas matched with NIST and WILEY Libraries.Results: The GC-MS analysis revealed the presence of 45 active compounds in the extract. From the GC-MS investigation, 1-Deoxy-d-mannitol3-methyl-2-methylsulfanyl-5-nitro-6-pyridin-4-ylpyrimidin-4-one, 3-Pentadecylphenol, 2-biphenylene carboxylic acid, Quinoline-3-carboxylic acid,and Stigmast-5-en-3-ol are important phytoconstituents which have antipyretic and antiparasitic activities.Conclusion: The present investigation revealed preliminary information on phytocompounds presented in S. jambos leaf extract which is very usefulfor the human community.Keywords: Syzygium jambos, Gas chromatography-mass spectrometry analysis, 1-Deoxy-d-mannitol, Phytoconstituents, Methanolic leaf extract.

Toxic normal hydrocarbon (NH), nonadecane in the methanolic extract of the whole of cabbage samples collected from different districts of Bangladesh was analyzed by GC-MS. It was observed that NH deposition on the samples takes place in different morphological parts of the biological materials. The NH, nonadecane, was found in the cabbage samples collected from the highway road side by the extraction of methanol. The identification and quantification of the title compounds have not been reported previously in the cabbage sample.   Keywords: Cabbage; brassica oleracea var. capitata f. alba; quantification; normal hydrocarbon, nonadecane, GC-MS
