Four sunflower accessions were compared with a susceptible check, hybrid '894', in the greenhouse to determine their resistance to the banded sunflower moth, Cochylis hospes Walsingham, and their interaction with Bacillus thuringiensis Berliner variety kurstaki. Antibiosis, expressed as lower larval weight, was detected in all of the accessions. In addition to being antibiotic, sunflower access...

The banded sunflower moth, Cochylis hospes Walsingham (Lepidoptera: Tortricidae), is an important economic pest of sunflower in the Upper Great Plains of North America. Economic losses due to reductions in seed number, weight, and quality can be significant. Previously, the potential for economic losses were estimated by sampling for adult moths. However, sampling for moths can be difficult and...

The effects of diets high in n-3 polyunsaturated fatty acids (PUFA; provided by fish oil), n-6 PUFA (sunflower oil) or in more-saturated fatty acids (tallow) on the distribution of subclasses of choline phospholipids (PC) and ethanolamine phospholipids (PE) from the breast muscle of broiler chickens were examined. Supplementation with the different fatty acids had no effect on the distribution ...

INTRODUCTION Essential fatty acids (EFAs) play a vital role in the human body and need to be taken through a regular diet. EFAs are susceptible to autoxidation, hence the stability of the EFAs and their products is a matter of concern. METHODS Margarine containing sunflower oil as a carrier of EFAs was prepared and the effects of water content, incorporation of EFAs, emulsifiers and antioxida...

The influence of fatty acid composition and tocopherol on cholesterol oxidation in fish, flax, sunflower, and palm oil to which cholesterol was added were examined during storage and heating. The contents of cholesterol oxides in all oils increased (p < 0.05) during storage and heating. Total cholesterol oxides in fish oil were higher (p < 0.05) than that in vegetable oils. Addition of R-tocoph...

The influence on the lipid profile and lipid peroxidation in rabbit-liver mitochondria exerted by different edible oils high in oleic acid but different non-glyceride phenolic fractions was studied. High-phenolic virgin olive oil from the variety “Picual”, the same oil submitted to an exhaustive process of washing to eliminate the phenolic fraction without altering the lipid profile and high-ol...

Identifying the best inbred combinations for the development of commercial hybrid of sunflower remains the main challenge to sunflower breeders. In the present research the level of heterosis of F1 hybrids, genetic diversity of parental lines based on SSR markers, as well as its connection with specific combining ability of sunflower were studied. Ten sunflower elite inbred lines (3 restorer li...

the antioxidant properties and total phenols’ content of 80% methanol, acetone and water extracts of olive leaves procured through microwave assisted extraction (mae) were examined. two varieties of olive namely: cronaiky and roghani were the ones studied. various experimental models were employed for antioxidant activity evaluation of the extracts. the results revealed the highest phenolic con...

in this study nine new varieties of sunflower seeds were obtained and subjected to oil extraction using soxhlet apparatus. the extracted oil was analyzed for fatty acid composition and phosphorus content to measure the phospholipid concentration. the results indicated that armavirski variety had the highest oil content. the fatty acid composition of the extracted oils indicated that armavirski ...

Plant oils have been utilized for a variety of purposes throughout history, with their integration into foods, cosmetics, and pharmaceutical products. They are now being increasingly recognized for their effects on both skin diseases and the restoration of cutaneous homeostasis. This article briefly reviews the available data on biological influences of topical skin applications of some plant o...
