Studying on lipid content and fatty acids in some varieties of colza (Brassica napus L.).

In this research, two of the most important biochemical characters such as total lipid and fatty acids combination in several seeds of different cultivars of colza (Brassica napus L.) were considered. In this research, extraction and measuring percentage of total lipid by soxhlet method and combination of fatty acids in seeds by Gas Chromotography were determined. The results of ten cultivars were compared with each other statistically. The highest percentage of oil was (44/46%) in Hyola 401 and least amount was (40/03%) in Eureka. Also 8 types of fatty acids were observed that includes, palmetic, palmitoleic, oleic, linoleic, linolenic, arachidic, eicosenoic and erosic acids. The most amount of the important fatty acids, oleic and linoleic were determined in the Navajo (72/57%) and 5hiralee (12/44%) respectively. Also erosic acid was not observed in the Navajo extract.
