ABSTRACT
A new, simple, rapid, accurate, precise and sensitive method has been developed for the simultaneous estimation of Furosemide and Spironolactone in their combined tablet dosage form. The method was carried out on a Hiber C18 column (250 mm×4.6mm, i.d.5 μm) with a mobile phase consisting of acetonitrile: water at a flow rate of 1 ml/min and the detection was carried out at 237 nm. The retention time of Furosemide and Spironolactone was 3.81 min and 7.28 min. respectively. Linearity for Furosemide and Spironolactone were found in the range of 2-10 μg/ml and 5-25 μg/ml respectively. The developed method was validated in terms of linearity, accuracy, and precision, limit of detection (LOD) and limit of quantification (LOQ). The proposed method can be used for estimation of both drugs in their combined dosage form.

Abstract:
A simple, precise, rapid, selective, and economic high-performance-thin-layer chromatography (HPTLC) method has been established for simultaneous analysis of Domperidone (DMP), Paracetamol (PCM) and Tramadol Hcl (TMD) in tablet dosage forms. The chromatographic separations were performed on precoated silica gel 60254 plates with toluene-ethylacetate-butanol-ammonia 5:4:1:0.2(v/v) as mobile phase. The plates were developed in a 7.0 cm at ambient temperature. The developed plates were scanned and quantified at their single wavelength of maximum absorption at approximately 278 nm for DMP and PCM, respectively. Experimental conditions such as chamber size, chamber saturation time, migration of solvent front, slit width, etc. were critically studied and the optimum conditions were selected. The drugs were satisfactorily resolved with Rf 0.18 ± 0.02 for DMP, Rf 0.25 ± 0.02 for PCM and for TMD Rf 0.50 ± 0.02. The method was validated for linearity, accuracy, precision, and specificity. The calibration plot was linear between 100-600 ng / band for DMP, 3250-19500 ng / band based for PCM and 375-2250 ng / band based for TMD. The limits of detection and quantification for DMP were 9.95 and 30.16ng / band, respectively; for PCM they were 64.30 ng and 194.87 ng / band and for TMD 5.51 and 16.70/ band. This HPTLC procedure is economic, sensitive, and less time consuming than other chromatographic procedures. It is a user-friendly and importance tool for analysis of combined tablet dosage forms.

Abstract:
The present manuscript described the simple, rapid, accurate, sensitive, precise and economical Q- absorption ratio method for simultaneous determination of Cefixime and Moxifloxacin in combined tablet dosage form. Absorption ratio method uses the ratio of absorbances at selected wavelengths, one which is isoabsorptive point and other being the λmax of the one of the components. Cefixime and Moxifloxacin shows isoabsorptive point at 275nm in 0.1N HCl. The second wavelength used is 295nm, which is λmax of Moxifloxacin. The concentrations of the drugs were determined by using ratio of absorances at isoabsorptive point and at λmax of Moxifloxacin. The method successfully applied to the Pharmaceutical formulation because no interference from the tablet formulation excipients was found. The results of analysis have been validated statistically and by recovery studies.

ABSTRACT :
A novel isocratic reverse-phase high performance liquid-chromatography method for determination of asenapine maleate was developed and validated after optimization of various chromatographic conditions. Samples were separated on a waters x-terra C18 (100 mm × 4.6 mm, 3.5 μ) analytical column. The mobile phase used was acetonitrile: 0.1M phosphate buffer (pH 3.2) 65:35%v/v operated at 30 °C column oven temperature was pumped at a flow rate of 1.0 mL min−1 and the column eluents were monitored at a wavelength of 272 nm. When sample was injected into the Finnigan surveyor high performance liquid-chromatography system through Finnigan surveyor auto-sampler injector, separation was achieved within 5.0 min. The present method demonstrated was validated with the acceptable values for selectivity, linearity (within the expected concentration range (10–50 μg mL−1; r2 > 0.999)), recovery (>95%), precision (%RSD < 2.0), sensitivity (limit of detection: 1.85 µg mL−1 and lower limit of quantification: 2.34 µg mL−1), robustness, and ruggedness.

ABSTRACT
A novel, accurate, precise, sensitive, economic and rapid spectrophotometric methods has been developed and validated for simultaneous estimation of Triamterene and Benzthiazide in bulk and pharmaceutical dosage form. Triamterene and Benzthiazide showed absorption maxima at 363 nm and 283 nm in ethanol, which is used as solvent. In the present study, Area Under Curve method (Method A) developed, employedthe measurement of area at selected analytical wavelength ranges. Two analytical wavelength ranges selected were 358nm to 368nm nm (lmax of Triamterene is 363nm) and 278nm to 288nm (lmax of Benzthiazide is 283nm) for the estimation of Triamterene and Benzthiazide respectively.  Ratio derivative method (Method B) employed the measurement of amplitudes of Triamterene and Benzthiazide at their respective selected wavelengths. Two wavelengths selected were 359.2 nm and 300.4 nmfor the estimation of Triamterene and Benzthiazide respectivelybased upon divisor method.  Linearity was observed in the concentration range of 6-30 μg/ml and 3-15 μg/ml for Triamterene and Benzthiazide respectively. The recovery studies ascertained the accuracy of the proposed method and the results were validated as per ICH guidelines.

ABSTRACT
Chromatography, although primarily a separation technique, is mostly employed in chemical analysis in which High-performance liquid chromatography (HPLC) is an extremely versatile technique where analytes are separated by passage through a column packed with micrometer-sized particles. Now a day reversed-phase chromatography is the most commonly used separation technique in HPLC. The reasons for this include the simplicity, versatility, and scope of the reversed-phase method as it is able to handle compounds of a diverse polarity and molecular mass. This review covers the importance of RP-HPLC in analytical method development and their strategies along with brief knowledge of critical chromatographic parameters need to be optimized for an efficient method development.

ABSTRACT
Churna are important group of formulation used by Ayurvedic physicians to treat various types of diasease. Trikatu and Pimpali churna, as per Ayurvedic literature is used for the treatment of resperatory disorders. In the present study,an attempt has been made to develop a HPTLC  method of quantitative estimation of marker compound, piperine in laboratory prepared authentic formulation and a marketed formulation of Trikatu and Pimpali churna. The stationary phase used was precoated silica gel G 60 F 254 plates. The mobile phase containing n- Hexane-ethyl acetate, (5:5 v/v ), was used to separate the spot of Piperine. Plates were developed to a distance of 8 cm at room temperature. Spectrodensitometric scanning was performed by TLC scanner III (CAMAG) in absorbance mode at the wavelength of 339nm. The  Rf  values of  piperine was 0.44± 0.02. The method was validated in terms of Linearity, Accuracy and  Precision. The linearity curve found to be linear in between 200–900 ng/spot. The limit of Detection (LOD) and limit of Quantification (LOQ) were found to be  1 ng and  3 ng respectively. The mean results from % Recovery was found to be, laboratory formulation contain 85.13% and 83.47% while the commercial formulation shows 96.65%, and 90.32% respectively. The proposed method can be used to determine Piperine from Ayurvedic formulations.

Abstract:
UPLC can be regarded as new invention for liquid chromatography. UPLC refers to Ultra Performance Liquid Chromatography. UPLC brings dramatic improvements in sensitivity, resolution and speed of analysis can be calculated. It has instrumentation that operates at high pressure than that used in HPLC & in this system uses fine particles(less than 2.5µm) & mobile phases at high linear velocities decreases the length of column, reduces solvent consumtion & saves time.
This review introduces the theory of UPLC, and it can summarizes some of the most recent work in the field.
