Abstract
Hydrazinocurcumin is a semi-synthetic analogue of curcumin with superior anticancer and anti-angiogenic activities. In the present work a simple and sensitive reverse phase high performance liquid chromatography (RP-HPLC) method for quantitative evaluation of hydrazinocurcumin in plasma and various organs of rats including liver, kidneys, brain, heart, lungs and spleen was developed. Hydrazinocurcumin was separated using octadecylsilane (Inertsil-ODS-3V) column in an isocratic mode using mobile phase consisting of methanol-acetonitrile- water (36:27:37 v/v) with flow rate of 1.0 ml/min. Ultra violet (UV) detection of hydrazinocurcumin and internal standard was carried out in dual-wavelength mode at 332 nm and 380 nm, respectively. The linearity of hydrazinocurcumin was found in the range 0.05-5 µg/ml with a correlation coefficient of r2 > 0.999. The developed bioanalytical method shown higher inter-day accuracy (98.04-105.94%) and precision (0.89-10.24). The average recoveries of hydrazinocurcumin from rat plasma and various organs were in the range of 96-101.75% and 92.25-99.0%, respectively. The bioanalytical samples shows good stability of hydrazinocurcumin at different storage and handling conditions. In conclusion, this validated HPLC-UV method could be applied effectively for evaluation of hydazinocurcumin for the pharmacokinetic and organ distribution studies.

Abstract
An optimized liquid chromatography-tandem mass spectrometry method for simple and sensitive quantification of Otaplimastat in rat plasma and brain tissue was developed and validated. Protein precipitation with acetonitrile was selected for sample preparation method based on recovery and matrix effect. The chromatographic separation of the sample was performed on a reverse-phase AQ column with an isocratic mobile phase consisting of 10 mM ammonium acetate (pH 4.0) and acetonitrile (50:50, v/v). The analyte was quantified by multiple reaction monitoring with a Waters Quattro micro™ API mass spectrometer. The lower limits of quantification were 20 ng/mL in plasma and 2 ng/g in brain, with the relative standard deviation % of 7.6 and 8.0% for plasma and brain samples, respectively. Acceptable intra-day and inter-day precisions and accuracies were obtained. Otaplimastat was sufficiently stable under all relevant analytical conditions, including a temperature of 4°C for 24 hr, room temperature 20°C for 24 hr, -80°C for 10 days and three freeze-thaw cycles (each at -80°C for 24 hr), for rat plasma and brain tissue. The validated method was successfully used to measure Otaplimastat concentrations in rat plasma and brain samples.

Abstract
In this work, a fast and low-cost voltammetric methodology for determination of carlina oxide in plant extracts was developed. The best results were obtained using a boron-doped diamond electrode (BDDE). The voltammetric measurements of carlina oxide were performed in a 0.1 mol/L solution of sulphuric acid. After 30 s of stirring the solution, differential pulse voltammograms (DPVs) were recorded from 0.5 to 1.8 V. The amplitude was 75 mV and the scan rate was 175 mV/s. Measurements were recorded in non-deaerated solutions. The background current was subtracted from each registered voltammogram; then they were cut from 0.5 to 1.5 V. The detection and quantification limits were 0.28 and 0.93 μg/L, respectively, and repeatability expressed as the relative standard deviation of 0.1 mg/L of carlina oxide was 1.9% (n = 5). The results were compared with those obtained using gas chromatography with a flame ionization detector and high performance liquid chromatography with a photodiode array detector.

Abstract
CONTEXT Tribulus terrestris L. (Zygophyllaceae) fruits have long been used in traditional systems of medicine for the treatment of various urinary diseases including urolithiasis. OBJECTIVE To explore the anti-urolithiatic potential of gokhru and to develop an analytical method for quantitative estimation of metabolites for its quality control. MATERIALS AND METHODS Aqueous extract of gokhru fruit was prepared through maceration followed by decoction to produce a mother extract, which was further used for polarity-based fractionations. In vitro and ex vivo anti-urolithiatic activity of mother extract and fractions at different concentration (100-1000 μg/mL) were carried out using aggregation assay in synthetic urine and in rat plasma, however, nucleation assay for 30 min was done using confocal microscopy. A simultaneous HPLC method has been developed for quantification of diosgenin, catechin, rutin, gallic acid, tannic acid and quercetin in mother extract and in fractions. RESULTS The extraction resulted in 14.5% of w/w mother extract, however, polarity-based fractionation yielded 2.1, 2.6, 1.5, 1.3 and 6.1% w/w of hexane, toluene, dichloromethane (DCM), n-butanol and water fractions, respectively. In vitro and ex vivo studies showed a significant anti-urolithiatic potential of n-butanol fraction. Further, HPLC analysis revealed significantly (p < 0.01) higher content of quercetin (1.95 ± 0.41% w/w), diosgenin (12.75 ± 0.18% w/w) and tannic acid (9.81 ± 0.47% w/w) in n-butanol fraction as compared to others fractions. DISCUSSION AND CONCLUSION In vitro and ex vivo studies demonstrated potent anti-urolithiatic activity of n-butanol fraction which can be developed as new phytopharmaceuticals for urolithiasis. HPLC method can be used for quality control and pharmacokinetic studies of gokhru.

Abstract
In recent years, the efficient analysis of biological samples has become more important due to the advances of life science and pharmaceutical research and practice. Because biological sample pretreatment is the bottleneck for fast process, material development for efficient sample process in the high-performance liquid chromatography analysis is highly desirable. In this research, a cation-exchange restricted access monolithic column was synthesized by a reversible addition-fragmentation chain transfer polymerization method. Utilizing the controlled/living property of the reversible addition-fragmentation chain transfer method, a monolithic column of cross-linked poly(sulfopropyl methacrylate) was prepared first and then linear poly(glycerol mono-methacrylate) was immobilized covalently on the surface of the polymer. The monolithic material has both functionalities of cation-exchange and protein exclusion. Protein recovery of 94.6% was obtained after grafting of poly(glycerol mono-methacrylate) while the cation-exchange property of the column is still retained. In the study, the relation between the synthetic conditions and properties of the materials was studied. The synthesis conditions including the porogen, monomer concentration, and ratio of monomers/initiator/reversible addition-fragmentation chain transfer agent were optimized. The study provided a method for the preparation of restricted access monolithic columns: a bifunctional material by reversible addition-fragmentation chain transfer polymerization method.

Abstract
α-Lipoic acid (LA) is a unique antioxidant that is not only effective in affording protection against oxidative stress but also plays an essential role in metabolic processes of all living organisms. Therefore, the determination of LA and its metabolites content is crucial for understanding their physiological and pathophysiological functions. Most of the recently developed methods for the detection and determination of LA and its metabolites in various biological samples have focused on sample preparation procedures involving but not limited to sampling, extraction and storage. The main goal of this review is to summarize and critically evaluate the current state of the art of analytical procedures applied to the determination of LA and related compounds in biological samples.

Abstract
There is an increasing need for new analytical methods that can handle a large number of analytes in complex matrices. Hydrophilic interaction chromatography (HILIC) has recently been demonstrated as an important supplement to reversed-phase liquid chromatography for polar analytes, particularly endogenous compounds. With the increasing popularity of HILIC, progressively more polar phases with diverse functional groups have been developed. In addition, the coupling of HILIC to mass spectrometry offers the advantages of improved sensitivity by employing an organic-rich mobile phase. This article reviews recent applications of HILIC for the analysis of endogenous and pharmaceutical compounds in plasma samples. Furthermore, based on recent studies, we provide a discussion of column selection, sample pretreatment for HILIC analysis, and detection sensitivity.
