Central Composite

In this study, central composite design (CCD) was used for optimization of high performance liquid chromatographic (HPLC) method for simultaneous analysis of curcumin (CUR) and demethoxycurcumin (DMC) in tablets containing Curcuma extract. Separation of CUR and DMC was performed using X-Bridge C18 column (250 x 4.6 mm i.d; 5 μm). Four factors that were investigated include the concentration of acetic acid (X1), ratio of acetic acid (X2), flow rate of mobile phase (X3) and column temperature (X4). Based on responses obtained (retention time, peak area, resolution and tailing factor), the optimum condition selected was X1 = 3.00%, X2 = 51%, X3 = 1.05 mL/min and X4 = 45oC. This HPLC condition was validated by assessing several validation parameters including system suitability test, selectivity, linearity, precision, accuracy and robustness according to International Conference Harmonization (ICH). All validation parameters meet the acceptance criteria set by ICH. The validated method was successfully used for analysis of CUR and DMC in tablets containing Curcuma extract. CCD was effective means in optimization of HPLC for analysis of CUR and DMC in pharmaceutical formulation.Dhaka Univ. J. Pharm. Sci. 16(2): 137-145, 2017 (December)

An accurate, sensitive, precise, economic and rapid isocratic Reverse Phase High Performance Liquid Chromatography method was developed complying Quality by Design (QbD) trends and validated for determining doxycycline hyclate in bulk drug, tablet and capsule dosage form. The method was optimized using Minitab software with 3 factors (pH of the buffer, flow rate and percentage of buffer in the mobile phase), 2 level (higher limit and lower limit) Central Composite Design (CCD). The results of randomized 20 runs were analyzed for optimum composite desirability to give optimum conditions such as, pH 6.5, flow rate 0.9 mLmin-1 and 30:70 V/V 0.05M potassium dihydrogen orthophosphate buffer adjusted to pH 6.5 using orthophosphoric acid and methanol using C8 column 250 X 4.6 mm X 5.0 μm, injection volume of 10uL, ambient column temperature and ultraviolet detection using photo diode array detector at 360nm as constants.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.

Abstract A rapid, accurate, and sensitive high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of ceftazidime in pharmaceuticals. The method validation parameters yielded good results and included range, linearity, precision, accuracy, specificity, and recovery. The excipients in the commercial powder for injection did not interfere with the assay. Reversed-phase chromatography was used for the HPLC separation on a Waters C18 (WAT 054275; Milford, MA) column with methanolwater (70 + 30, v/v) as the mobile phase pumped isocratically at a flow rate of 1.0 mL/min. The effluent was monitored at 245 nm. The calibration graph for ceftazidime was linear from 50.0 to 300.0 g/mL. The values for interday and intraday precision (relative standard deviation) were <1. The results obtained by the HPLC method were calculated statistically by analysis of variance. We concluded that the HPLC method is satisfactory for the determination of ceftazidime in the raw material and pharmaceuticals.

Abstract A sensitive, precise, and specific gas chromatographic (GC) method was developed for the analysis of capsaicin in Gochujang and validated by comparing with a column high-performance liquid chromatographic (HPLC) method (AOAC 995.03). The method validation parameters yielded good results, including linearity, precision, accuracy, and recovery. The GC separation was performed on a (5 phenyl)-methylpolysiloxane column [length 30 m, internal diameter (id) 250 μm, film thickness 0.25 μm] followed by flame ionization detection. The conditions of temperature programming were initially 220Cfor 1min, rampat5C/minto270C, and hold for 10 min. The recovery of capsaicin in Gochujang was more than 92, and the detection limit and lower determination limit of the GC analysis were 1.0 and 5.0 μg/g, respectively. The calibration graph for capsaicin was linear from 1 to 250 μg/mL for GC and 0.5 to 50 μg/mL for HPLC. The interday and intraday precisions (relative standard deviations) were <4.02.
