Objective: Evaluation activity was conducted using three spearmint genotypes (WG-SPM-Engl, SPM-Fran and SPM-EAS) and one standard check (WGSM-03) at Wondo Genet, Awassa, Debre Zeit and Allagae during 2012 and 2013 for two years. Methods: The treatments were arranged in randomized complete block design with four replications. Data on leaf to stem ratio, leaf yield/ha, Essential oil content and e...

introduction: using oilseeds in the human food stuffs, employing their meal for animal feed and also their usage in pharmaceuticals, soap making and fuel has prompted great interest for farmers to plant them and for the government to promote their cultivation. among them, sunflower is one of the main oilseeds in the world which its cultivated area has expanded due to fair cultivation requiremen...

In preceding reports (1, 2) it was shown that when fish oil was fed to white rats equilibrium between the diet and the depot fat resulted in from 4 to 6 weeks, and further that with a series of diets containing from 5 to 30 per cent of menhaden oil the amount of highly unsaturated acids in the depot fat was roughly proportional to their content in the diet. Relatively more of these acids, howev...

Palm oil is one of the major fats and oils produced and traded in the world today. It forms an important ingredient in the diet of many people in West Africa. The quality of palm oil is mostly determined by the fatty acid, moisture and impurity content, and bleachability. This study examined the quality of palm oil produced at cottage industry level in Ghana with a view to improve its quality t...

The oils of some unconventional oilseeds (hemp, radish, terebinth, stinging nettle, laurel) were obtained by a cold-press method in which the total oil content, fatty acids, tocopherol isomers, some metal contents (Ca, Mg, Fe, Cu), antioxidant activity and oxidative stability were determined. The total oil content was determined ranging between 30.68 and 43.12%, and the oil samples had large am...

Accurately measuring the oil content and salt content of crude oil is very important for both estimating oil reserves and predicting the lifetime of an oil well. There are some problems with the current methods such as high cost, low precision, and difficulties in operation. To solve these problems, we present a multifunctional sensor, which applies, respectively, conductivity method and ultras...

BACKGROUND AND AIMS Sunflower cultivars exhibit a wide range of oil content in the mature achene, but the relationship between this and the dynamics of oil deposition in the achene during grain filling is not known. Information on the progress, during the whole achene growth period, of the formation of oil bodies in the components of the achene and its relationship with variations in final oil ...

flaxseed oil is known as a functional oil because of the high content of α-linolenic acid; therefore, the aim of this research was to investigate some physicochemical properties of iranian extra virgin flaxseed oil (evfo) and the impact of the refining stages before deodorization on these properties. fatty acid composition, peroxide and anisidine values, free fatty acids, crystallization point,...

in order to investigate the effects of mycorrhiza symbiosis and different nitrogen levels on yield, yield components and essential oil content and yield of fennel (foeniculum vulgare mill.) and ajowan (carum copticum l.), a field experiment was arranged in a factoriel based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of...
