Abstract
The fatty acid composition of tobacco seed oil revealed that the oil is rich in unsaturated fatty acids, having linoleic acid (71.63%), oleic acid (13.46%) and palmitic acid (8.72%) as the most abundant unsaturated and saturated fatty acids respectively. So the tobacco oil was characterized as semiβdrying type on the basis of fatty acid composition. The synthesis of alkyd resin was carried out by alcoholysis or monoglyceride process using an alkali refined tobacco seed oil, pentaerythritol, cisβ1,2,3,6βtetrahydrophthalic anhydride along with lithium hydroxide as catalyst. The alkyd resin so prepared was found to be bright and of low color with high gloss. The drying and hardness properties and adhesion of the tobacco seed oil derived alkyd resin were also found a bit superior to those of other alkyd resins of the same oil length. In addition, the water and acid resistance of the said alkyd was also found comparable to the other alkyds.

The seeds of 28 species from 'cerrado', a typical savanna ecosystem of Brazil, were analysed for total lipid contents and fatty acid distribution. The seeds of 10 species presented contents above 150 g kg-', the highest yield reaching 335 g kg-'. Distribution of fatty acids based on polyunsaturated
From our data it could be summarized that the low silica gellecithin extract ratio (2:l) allows to obtaine rapeseed lecithin with above 80 % content of phosphatidylcholine. The best results (yield 44 %, 82 % PC) for temperature 60Β°C were observed. The method presented in this report could be useful
for his keen interest in the study.
