Marine oils are important to human nutrition as the major source of docosahexaenoic acid (DHA), a key omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) that is low or lacking in terrestrial plant or animal oils. The inclusion of fish oil as main source of n-3 LC-PUFA in aquafeeds is mostly limited by the increasing price and decreasing availability. Fish oil replacement with ch...

African oil palm has the highest productivity amongst cultivated oleaginous crops. Species can constitute a single crop capable to fulfill the growing global demand for vegetable oils, which is estimated to reach 240 million tons by 2050. Two types of vegetable oil are extracted from the palm fruit on commercial scale. The crude palm oil and kernel palm oil have different fatty acid profiles, w...

conclusions concerning the ability of salicorniaeuropea to survive in the contaminated areas, it might be suitable that endemic types of this plant would be cultivated in contaminated coast lines. results the highest uptake was at eight mg crude oil, per one g of soil and the least uptake was at 13.75 mg crude oil, per one g of soil. it seems that physical characteristics of crude oil are the m...

conclusions antioxidant activity of this essential oil could be somehow attributed to high contents of carvone, carvacrol and thymol. the volatile oil of this plant could have the potential of other biological activities, so further experimental investigations are recommended on this essential oil. results analyses of yellow colored essential oil yielded 88.22% of total oil with 67 components. ...

Whitefly (Bemisia tabaci) is an important insect pest, causing severe damage to agricultural crops. The pest was recorded in a commercial rosemary (Rosmarinus officinalis, Lamiaceae) field, colonizing rosemary variety (var.) '2', but not '11'. A series of field and controlled laboratory choice bioassays confirmed the observed phenomenon. Mature potted plants of the two varieties were randomly o...

in order to study the effect of density and time of urea foliar application on oil yield and essences percentage of black cumin (nigella sativa l.) a field experiment was conducted at research station of faculty of agriculture, azad university of birjand in 1387 growing season. three urea foliar application times [1-control 2-at 8-10 leaves stage 3-at 10% flowering 4-100% flowering ] and three ...

Trigonella foenum-graecum, commonly called fenugreek, is a leguminous plant native to many Asian, Middle Eastern and European countries. Fenugreek oil is very effective in digestion. Identification of fenugreek genotype rich in saponins and fixed oil will be useful for pharmaceutical industries. In the present study, steroidal saponin and fixed oil content was analysed in 46 diverse fenugreek g...

Interest for vegetable oil is growing, especiallywith the increasing demandon fossil oil substitutes. World oil production is close to 135Mt with palm, soybean and rapeseed oils representing 31%, 24% and 15% respectively. In Europe, rapeseed is the major source of oil (69%). Most of this production is devoted to food uses, followed by emerging uses of oil as bio fuels, and to a lesser extent, a...

In order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of Islamic Azad University, Birjand Branch, Birjand, Iran in 2010 based on a randomized complete block design with three replications. The main plots were nitrogen rates at four levels (0, 40, 80 and 120...

essential oil extracted from the leaves of myrtle, myrtus communis l. (myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (tribolium confusum and callosobruchus maculatus). the chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (gc-ms). the major oil components were α-pinene (10.4%), α- terpineol (10.1%), linalool (9.0%...
