Castor oil is non-edible and differs from all other oils as having a major constituent of ricinoleic acid (90%). Compared to all other oils, castor oil is highly viscous, less soluble in hexane and more soluble in ethanol due to the presence of ricinoleic acid, a hydroxyl fatty acid. Th...
CONSTITUTION:An oil-soluble vitamin such as vitamin K, vitamin A, coenzyme Q or vitamin D and a carotenoid (e.g. beta-carotene) are dissolved in an oil component such as colza oil or an organic solvent such as n-hexane and uniformly blended. Further the solution is optionally mixed with...
Soy contributes to the production of neutoroxins in the digestive tract. There is no hexane left in a food after it is used within it. Byanon84511— On May 16, 2010 I habitually use soy milk, and have recently started using the soy 'meat' products. News about the use of the neuro-...
Bis(pinacolato)diboron is insoluble in water but soluble in common organic solvents, including non-polar solvents such as petroleum ether and hexane, and low-polarity solvents such as ether. It is worth mentioning that in the literature, Bis(pinacolato)diboron is often further purified by recrystal...
The brownish oily residue was dissolved in 0.1 ml of benzene- methanol (9:1) and the products were methylated by adding 0.02 ml of trimethylsilyldiazomethane10% in n-hexane) for 15 min at ambient tempera- ture. After removal of solvent by evaporation, the methylated products were re-...
For volatile organic compounds (VOCs) to be released from the plant cell into the atmosphere, they have to cross the plasma membrane, the cell wall, and the cuticle. However, how these hydrophobic compounds cross the hydrophilic cell wall is largely unkn
Oils extracted withn-hexane fromEucalyptus camaldulensisandVitex agenus-castusand the treated wood ofM. azedarach(Figs. 6–8) showed promising antifungal activities, while the oil extracted fromMatricaria chamomillawas observed to have the lowest activity [19]. In these Figures, each wood block had...
Hexane extract of stems inhibited the survival of P. falciparum (FcM29-Cameroon chloroquine-resistant strain) with the IC50 values of 13.7 µg/mL and was inactive for B. divergens (Rouen 1986 strain), and L. infantum (line MHOM/MA/67/ITMAP-263) Commentary: The specific in vitro ...
the ethanolic extract demonstrated an inhibition zone of 12 mm at a concentration of 100 mg/ml, whereas the aqueous extract only achieved an inhibition zone of 8mm. This discrepancy was attributed to the active ingredients present in the date seeds which could have been more soluble in ethanol ...
The ethanol-soluble fraction was filtered and concentrated using a vacuum evaporator at 40 °C. This extracts were suspended in distilled water and successively partitioned with n-hexane, dichloromethane (CH2Cl2), ethyl acetate (EtOAc) and n-butanol (n-BuOH). Repeated chromatography of the n-...
