A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations were tested in this study: 5, 7.5...

A novel continuous subcritical n-butane extraction technique for Camellia seed oil was explored. The fatty acid composition, physicochemical properties, and benzo[a]pyrene content of Camellia seed oil extracted using this subcritical technique were analyzed. Orthogonal experiment design (L9(34)) was adopted to optimize extraction conditions. At a temperature of 45 °C, a pressure of 0.5 MPa, a t...

background and objectives: soybean is one of the plants that need large amounts of nitrogen for grain yield production. todays bio-fertilizers are considered as a best replacement for chemical nitrogen to increase soil fertility and sustained agricultural production. meanwhile, the use of soybean symbiotic bacteria and nitroxin, which contain the most effective nitrogen-fixing bacteria of the g...

Irrigated rapeseed (Brassica napus L.) cultivation is currently expanding in rotation with winter cereals in Iran where its reproductive growth is often exposed to water deficit in many parts, particularly in the south. A two growing seasons (2006-2008) field experiment was conducted at the Experimental Research Center, Shiraz University to study the effects of water stress at different growth ...

Background & Aim: Black seed or black cumin (Nigella sativa L.) belongs the family Ranunculaceae. Black seed is one of these species, which is naturally distributed in different parts of the country. It is extensively cultivated in various regions of Iran.  Experimental: The experiment was achieved using randomized complete block desi...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...

This work focuses on the study of the oil extraction yield from castor seed using three different seed conditions: whole, minced and bare endosperm. Taguchi design was used to determine the contribution of the following parameters: seed condition, seed load in the extractor, temperature, and pressure. It was proved that it is necessary to introduce the whole seed and that the presence of the pe...

seed and oil yields, their components, and the relationships among trait performance were determined in 25genotypes of winter type oilseed rape (brassica napus l.). the experiment was carried out at the agricultural and natural resources research center of east azerbaijan, iran, in two consecutive growing seasons 2009-10 and 2010- 11. significant differences were observed in plant height, numbe...

The research work comprising genetic studies for oil, fatty acid profile, seed cotton yield and lint percentage in eight parental lines (SLH-284, CIM-446, CIM-473, CIM-496, CIM-499, CIM-506, CIM-554, CIM-707) and their F3 populations was carried out during 2011 and 2012 at The University of Agriculture, Peshawar and Nuclear Institute for Food and Agriculture, Peshawar Pakistan. The genetic pote...
