A chloroform extract of the mycelium of Fusarium oxysporum Schl. em. Sny. et Hans, was analyzed for sterols; three major components were identified as ergosterol, ergosterol peroxide, and cerevisterol. The ratio of ergosterol to ergosterol peroxide formed was variable. Palmitic, stearic, oleic, and linoleic acids were identified by gas–liquid chromatography as the principal fatty acids of this organism.Fusaric acid, a phytotoxin previously obtained by other investigators from a number of forms of F. oxysporum, was isolated from the culture medium.

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.

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.

Total petiolar fatty acid content of sicklepod (Cassia obtusifoliaL.) treated with 0, 0.14, 0.28, 0.56, 1.12, 2.24, or 4.48 kg/haS-ethyl dipropylthiocarbamate (EPTC) was measured by gas-liquid chromatography. Neither total petiole fatty acid content nor percentages of the various 53 identified constituents changed in relation to herbicide application. Isostearate (17.5%), stearate (5.7%), oleate (5.7%), linolate (9.8%), and arachidate (8.2%) accounted for 46.9% of the total petiole fatty acid content. Anteiso derivatives of C15to C31were identified and quantitated at concentrations of 0.25 to 2.00%. Petiole cuticle thickness decreased 35% as herbicide concentration increased to 4.48 kg/ha.

Fatty acids of liver, carcass, and milk of rats fed corn oil, rapeseed oil, partially hydrogenated herring oil, or margarine were examined by gas–liquid chromatography. Appreciable quantities of linoleic acid were maintained in the tissues and milk, even when the hydrogenated herring oil with a low level of linoleic acid was fed. The proportion of C20and C22acids deposited or secreted was related to that of the diet, and was highest with rapeseed oil. In the livers of rats fed each diet, long-chain, polyunsaturated acids were observed. The fatty acids of milk more closely reflected the dietary pattern than did those of the tissues.

Nefa Level

The level of plasma non-esterified fatty acids (NEFA) was measured by gas-liquid chromatography (GLC) and a titration method in 194 samples collected during pregnancy and from four days to 24 weeks post partum. Both techniques indicated a similar pattern of changes in plasma NEFA associated with pregnancy. The titration estimates of NEFA level were usually greater than those measured by GLC, and there was some suggestion that the disparity between the methods was increased at the end of pregnancy and was reduced at six weeks after delivery.
