A Rapid Hplc Method for Determination of 4-hexylresorcinol Residues in Shrimp
نویسندگان
چکیده
A rapid method for the extraction, separation and quantification of the 4-hexylresorcinol from shrimp with high performance liquid chromatography (HPLC) is described. This modified method is faster than previously described methods with short pre–preparation and sharp resolution in HPLC procedures (sample preparation, extraction, separation and quantification total 40 min.). The coefficients of determinations (r2) measured for 4-hexylresorcinol were obtained over 0,999 in each curve. The confidence interval of the recovery working range of 1.5–2.5 mg/kg was approximately 95%. Limits of detection and quantitation were determined as 0.04 and 0.06 mg/kg for shrimp.

Determination of 4-hexylresorcinol in shrimp by liquid chromatography with fluorescence detection.
A method was developed to determine 4-hexylresorcinol in shrimp meat. The procedure is based on extraction of test portions with methanol followed by liquid chromatographic analysis of the extracts, using a reversed-phase column and fluorimetric detection (excitation: 280 nm, and emission: 310 nm). The confidence interval of the recovery in working range of 1.5-2.5 mg/kg was 81.6 +/- 0.8%. The ...
متن کاملSimultaneous Chloramphenicol and Florfenicol Determination by A Validated DLLME-HPLC-UV Method in Pasteurized Milk
The antibiotic residues in milk are a well-known serious problem and pose several health hazards to consumers. We have described a simple, rapid, and inexpensive DLLME-HPLC/UV technique for the extraction of chloramphenicol and florfenicol residues in milk samples. Under the optimum conditions, linearity of the method was observed over the range 0.02-0.85 µg/L with correlation coefficients > 0....
