Purpose: To assess the potential of Azolla filiculoides, total body collected from a rice farm in northern Iran as source for biodiesel production. Methods: Solvent extraction using Soxhlet apparatus with chloroform-methanol (2:1 v/v) solvent blend was used to obtain crude oil from freeze-dried the Azolla plant. Acid-catalyzed transesterification was used to convert fatty acids (FA), monoglycer...

During investigations of new sources of higher plant lipids, seed fatty acid compositions and the tocopherol contents of some Isatis sp. (Isatis cappadocica subsp. steveniana, I. kotschyana, I. candolleana, I. spectabilis, I. glauca subsp. glauca and I. kozlowskyi) (Brassicaceae) were investigated by using GC and HPLC system. Some of the species are endemic to Turkey. All the Isatis species sho...

The fatty acids, cholesterol compositions and the ratio between unsaturated saturated acids are important parameters for determination of nutritional value certain oils. Most oils sold in our markets claimed they cholesterol- free their acid profile is unknown. To determine commercially vegetable three places, twelve oil samples were analyzed compositions. Cholesterol was detected most sample e...

Male Sprague-Dawley rats were fed diets that contained 20% by weight soybean oil or rapeseed oil (21% and 43% erucic acid) for 7 days. The rapeseed oil diets increased the cardiac triacylglycerol content 5-fold and 25-fold, respectively, above control values. Hearts were removed from the animals and perfused with modified Krebs-Henseleit buffer at 37 degrees C. The calculated rate-pressure prod...

Biosynthesis of very long chain (>C18) fatty acids (VLCFAs) and the pathway for their incorporation into acyl liipids was studied in microspore-derived (MD) and zygotic embryos of Brassica napus L. cv Reston. In the presence of [1-'4C]oleoyl-coenzyme A or [1-14C] eicosenoyl-coenzyme A, malonyl-coenzyme A, and reducing equivalents, maximal in vitro elongation activity was expressed in protein pr...

The safety and shelf-life of food products can be, respectively, ensured and extended with important food-processing technologies such as irradiation. The joint effect of cooking and 10 kGy gamma irradiation on the fatty acid composition of the oil of Pentaclethra macrophylla Benth was evaluated. Oils from the raw seed, cooked seeds, irradiated seeds (10 kGy), cooked, and irradiated seeds (10 k...
