Abstract:

The investigation focused on the analysis of the hexane extract obtained from the bark of Syzygium cumini originating from India. Through chromatographic techniques, both traditional column chromatography and gas chromatography mass spectrometry (GC-MS), the oily fraction of the bark was examined, leading to the identification of numerous ester and hydrocarbon compounds. While the initial hexane eluate yielded waxy substances, which were challenging to separate through column chromatography due to their limited quantity, GC-MS analysis facilitated the identification of 39 compounds. These compounds were matched with existing literature through comparisons of retention times, Kovats indexes, and interpretation of mass spectra. Many of these identified compounds find applications across industries such as perfumery, flavoring, deodorants, antiseptics, and pharmaceuticals. This study aimed to elucidate the chemical composition of the hexane extract from S. cumini bark, particularly focusing on the identification of hydrocarbons and esters.

Key words: Syzygium cumini (bark), esters, hydrocarbons, signals, peak gas chromatography -mass spectrometry
