Abstract Rabbit meat is a good source of protein as compared to beef and chicken. The processing of rabbit meat gives attractive texture with a strong flavor. Charcoal grilling is a well-known cooking method which results in the formation of polycyclic aromatic hydrocarbons. Therefore, to determine the concentration of PAHs, rabbit meat samples were prepared with and without additives and analyzed for six PAHs (naphthalene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene) using gas chromatography-mass spectrometry (GC-MS). Naphthalene was dominant in all the samples and the highest naphthalene concentration (2.61 µg/g) was found in the foreleg sample (without additives) due to the presence of higher fat molecules. PAHs concentration was found to be significantly (p ≤ 0.05) lower by the addition of antioxidants. Lowest naphthalene concentration was observed in the back sample of seekh kebab (0.77 µg/g) with 1 h marinating duration. The content of pyrene was only noticed in foreleg (0.01 µg/g) and hind leg (0.03 µg/g) samples from reshmi kebab. The content of fluorene was not observed in all the samples.

Abstract Rare earth nano sized pollycrystalline orthoferrites and orthocromites R e T mO3 (Re = La, Nd, Gd, Dy, Y and Tm = Fe, Cr) have been synthesized by sol-gel auto combustion citrate method. The samples have been characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), and UV-visible spectroscopy. The samples are single phase, as confirmed by XRD analysis, and correspond to the orthorhombic crystal symmetry with space group pbnm. Debye Scherer formula and Williamson Hall analysis have been used to calculate the average grain size, which is consistent with that of determined from SEM analysis and varied between 25-75 nm. The elemental compositions of all samples have been checked by EDX analysis. Different crystallographic parameters are calculated with strong structural correlation among Re and Tm sites. The optical energy band gap has been calculated by using Tauc relation estimated to be in the range of 1.77 - 1.87 eV and 2.77 - 3.14 eV, for ReFeO3 and ReCrO3, respectively.

A simple, precise, sensitive and validated reverse-phase high performance liquid chromatographic (RP-HPLC) method was developed for the simultaneous estimation of rosuvastatin and ezetimibe in human plasma. The method involved protein precipitation and extraction of both drugs from plasma using acetonitrile and then separation on a C-18 column. Both the analytes were detected at a wavelength of 240 nm using diode array detector. Mobile phase for the said separation consists of a mixture of 1.5% phosphoric acid and acetonitrile in 30:70, v/v ratio. Linearity was in the range of 0.32-267 mg/mL for rosuvastatin and 0.08-67 mg/mL for ezetimibe with coefficient of determination between 0.9997 and 0.9967. Limit of detection was 0.106 μg/mL for rosuvastatin and 0.026 mg/mL for ezetimibe whereas limit of quantification was 0.32 mg/mL and 0.08 mg/mL for rosuvastatin and ezetimibe respectively. Recovery of both the analytes was greater than 75% with RSD less than 15 %. The total run time was less than five min for the two components. The developed method can be fruitfully employed for the determination of these two drugs in human plasma.
