hexane

Results of genotoxicity caused by the alcoholic and hexane extracts are shown in Table I.

Pure methanol, ethanol, chloroform, and hexane were used as negative control based on solvent of extraction.

The scientists prepared a first group of emulsions from an oil phase using 0.1% to 20% thymol in hexane. The samples were emulsified at 10% of the volume of the overall emulsion with a fixed amount of conjugates, corresponding to thymol loading levels of 1.1% to 69%.

Copitarsia decolora larvae fed on a diet supplemented with hexane extracts of T.

The plant material was dried under shade and powdered for separate extraction processes using maceration with hexane, ethyl acetate, and hydroalcoholic [ethanol (70% v/v)], and then concentrated to dryness under vacuum using rotavapour.

Prunus dulcis are already evaluated worldwide regarding characterization of oils on basis of physicochemical parameters, profiling of their lipids by conventional industrial adopted extraction technique - Soxhlet extraction with hexane and ether as extracting solvents (Ashraf et al., 2011; Fatima et al., 2012).

The remaining oil is then taken to a series of vessels where it is treated with acids, alkalis and other chemicals to neutralize any remaining hexane and to remove the free fatty acids, the rancidity and the odour.

HPLC grade solvents (hexane, ethanol, and methanol), boron trifluoride (B[F.sub.3]), NaOH, and NaCl were purchased from Sigma Chemical Co.

Fraction 2 (F2) of hexane showed antibacterial activity against three pathogens, while ethanol F4 exhibited antibacterial activity against A.
