A CE-tandem mass spectrometry (MS²) methodology enabling the simultaneous determination of betaines (glycine betaine, trigonelline, proline betaine and total content of carnitines) in vegetable oils was developed. Betaines were derivatized with butanol previous to their baseline separation in 10 min using a 0.1 M formic acid buffer at pH 2.0. Ion trap conditions were optimized in order to maxim...

Recently there has been an increasing interest in the classification of edible oils as an effective means to examine authenticity and to detect possible adulteration of virgin olive oils with seed oils or low-quality olive oils. Classical methods based on gas chromatography (GC) and high-performance liquid chromatography (HPLC) are too expensive for widespread industrial use and require samples...

the purpose in this research was to study the effects of vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (coriandrum sativum l.) in the shahr-e- ghods region. a factorial experiment using the randomized complete block design with three replications was conducted in the islamic azad university of shahr-e- ghods. the first factor was three levels of ...

UNLABELLED Botanical seed oils reduce the generation of leukotrienes in patients with asthma. Our objective was to determine the efficacy of a botanical seed oil combination against airflow obstruction in asthma, and to determine the pharmacogenomic effect of the leukotriene C4 synthase (LTC4S) polymorphism A-444C. We conducted a randomized, double-blind, placebo-controlled, cross-over clinical...

ferulago angulata (apiaceae), a medicinal plant of western asia, contains essential oils that areused as a food preservative. this study examined and compared the composition of leaf oil with seed oil andof the oils from two different habitats (one from nevakov and the other from shahoo). the oil yield from seedwas 5-fold that from leaves (3.2%/100g compared to 0.63%/100g). cis-ocimene was the ...

in this study, antioxidant activity of kolkhung skin oil, baneh skin oil and seasame oil were compared. the ratio between polyunsaturated to saturated fatty acids (pufa/sfa) of kolkhung skin oil, bane skin oil and seasame seed oil were 0.52, 0.26 and 3.06, respectively. total phenolic contents of kolkhung skin oil, bane skin oil and seasame seed oil were 99.67, 645.73 and 81.72 mg/kg, respectiv...

Chia (Salvia sp) seeds were investtgated as a source of natural lipid antioxidants. Methanolic and aqueous extracts of defatted chia seeds possessed potent antioxidant activity. Analysis of 2 batches of cbia-seed oils demonstrated marked difference in the fatty acid composition of the oils, In both batches, the oils had high concentrations of polyunsauarated fatty acids. The major antioxidant a...

Oilseeds and edible oils are two of the most sensitive essential commodities. Oilseeds are important sources of edible oils of nutritional, industrial, and pharmaceutical importance. Groundnut, mustard/rapeseed, sesame, safflower, linseed, niger seed, castor are the major traditionally cultivated oilseeds. Soybean and sunflower have gained high importance in recent years, while coconut is most ...

The aims of the study were to determine the in vitro cytotoxicity and anti-inflammatory activities of common edible herbs and spices on cultured human gingival fibroblasts (HGFs). Piper betle L. (betel leaf), P.sarmentosum Roxb. (wild betel / kadok leaf), P.nigrum L. (black pepper seed), Eugenia caryophyllata L. (clove bud) and Cinnamomum zeylanicum Blume (cinnamon bark). Essential oils were ex...

Botanical larvicides have featured prominently as alternative to synthetic chemical insecticides which are less degradable and toxic to non-target organisms. The larvicidal potentials of the seed oils of Pterocarpus santalinoides and Tropical Manihot species (TMS 30572) were investigated in the laboratory against larvae of Aedes aegypti. The seed oil of each plant was extracted using n-hexane a...
