Abstract
The fatty oil content of Osteobrama belangeri and its chemical compositions were determined by the analysis of fatty acid methyl esters using gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). A total of eighteen compounds were identified constituting about 96.1% and 96.7% of the crude head and body oils. Ten compounds were identified as major fatty acids in the oil and the main acids were oleic acid (38.3 and 35.1%), palmitic acid (27.3 and 23.9%), linoleic acid (12.6 and 21.8%) and octadecanoic acid (8.7 and 7.7%) besides two trace fatty acids.
Key words: Fatty oil composition, Osteobrama belangeri, oleic acid, palmitic acid.
