Determination of melengestrol acetate in supercritical fluid-solid phase extracts of bovine fat tissue by HPLC-UV and GC-MS.
نویسندگان
چکیده
A method is developed for the determination of melengestrol acetate in bovine fat tissue at or less than the established tolerance level of 25 ppb. The procedure uses a combination of supercritical fluid extraction (SFE) and solid-phase extraction (SPE) techniques to produce an extract suitable for analysis with either high-performance liquid chromatography with ultraviolet detection or gas chromatography-mass spectrometry. Overall recovery of the analyte from bovine fat tissue is 99.4% with a coefficient of variation of 4.14%. The SFE-SPE procedure uses a total of 12 mL of organic solvent per fat tissue sample versus more than 1.7 L consumed in current extraction procedures.

The use of supercritical fluid extraction for the determination of steroids in animal tissues.
A multi-analyte, multi-matrix method was developed for the routine determination of steroids in animal tissues (skin, meat and fat). After addition of internal standards and sample pre-treatment, the analytes of interest were extracted from the matrix with unmodified supercritical CO2 and trapped directly on an alumina sorbent placed in the extraction vessel (in-line trapping under supercritica...

1.Abstract Food additives play an important role in today's complex food supply, nevertheless, they represent one of the most misunderstood topic in food safety that raises consumer's concern. Food additives are intentionally added to food in order to produce a desired positive effect, although their level has to be maintained within regulated limits. At present, there is an enormous interest i...
متن کاملThe fate of trenbolone acetate and melengestrol acetate after application as growth promoters in cattle: environmental studies.
The steroids trenbolone acetate (TbA) and melengestrol acetate (MGA) are licensed as growth promoters for farm animals in several meat-exporting countries. Although many studies have explored their safety for both animals and consumers, little is known about their fate after excretion by the animal. Our study aimed to determine the residues and degradation of trenbolone and MGA in solid dung, l...
