Proximate Analyses

Anethum sowa L. (Dill) seeds were investigated to determine the fatty acid composition and proximate analyses. The seeds contain 9.36 % fatty oil. The saturated and unsaturated fatty acids contributed 6.22% and 93.78% respectively of the oil. The per cent composition of the extracted oil was identified by Gas Liquid Chromatography (GLC). Among the six fatty acids identified from this study oleic acid contributed the highest proportion (87.10%), where as, linolenic, palmitic, stearic, behenic and arachidic all together contributed the rest (12.90%). Proximate analyses showed that A. sowa. seeds are good source of dietary fibre. Overall Dill seeds oil can be considered as a good source of oleic acid. Key words: Anethum sowa, dill seed oil, fatty acid composition, oleic acid, linolenic acid, Gas liquid chromatography. Bangladesh J. Sci. Ind. Res. 42(4), 455-464, 2007

Fatty Acid Compositions

SUMMARYGas liquid chromatography was used to investigate the influence of several T, S and unclassified cytoplasms on the fatty acid composition of oil from A632 and CrS4HLA maize seeds. The fatty acid compositions of the A632 and CrS4HLA seeds differed markedly from each other with respect to oleic and linoleic acids but were stable within each seed line with respect to all sixteen of the cytoplasms tested.

Phase Variants

The total saponifiable fatty acids of three stable L-phase variants of Staphylococcus aureus induced by cycloserine, methicillin, and lysostaphin were examined by gas-liquid chromatography. Five separate preparations of each of the three variants were examined. Twenty-nine fatty acids were identified. The fatty acid patterns of the three variants were very similar.

Long Chain

The fatty acid composition of 20 species of marine animals, primarily fishes and crustaceans, was determined by gas–liquid chromatography. The species came from various depths down to 4400 m. The results showed that the medium-chain saturated and the long-chain polyunsaturated acids decreased with increasing depth, while oleic acid increased. It was thought that this indicated the presence of large amounts of wax esters. A benthic, mud-feeding holothurian Scoloplanes theeli was shown to have a fatty acid composition markedly different from that of pelagic species. This was attributed in part to the bacterial components of its diet.
