Analyses of Total Alkaloid Extract of Corydalis yanhusuo by Comprehensive RP × RP Liquid Chromatography with pH Difference
A comprehensive two-dimensional (2D) reverse phase (RP) liquid chromatography (LC) method is developed for alkaloid analysis. This offline comprehensive 2D method is developed using different pH values. With a pH value of 10.5, most alkaloids appear in the form of neutral molecules possessing high retention factors based on their polarity, while the alkaloid polarity order is changed when the p...
متن کاملDetermination and Validation of Eflornithine Hydrochloride by (Rp-Hplc) Reversed Phase High Performance Liquid Chromatography
A simple highly sensitive, rapid, precise, accurate and specific RP-HPLC method was developed for quantification of eflornithine hydrochloride (2-difluoromethyl-DL-ornithine; DFMO) in its commercial formulation. In this RP-HPLC method, the separation was performed using BDS Hypersil 5μ C18 (150 X 4.6 mm) column at room temperature by using methanol: 2% of Glacial acetic acid in water (80:20 v/v...
متن کاملReview on Rp-high Performance Liquid Chromatography Method for Bio Analysis of Verapamil in Rat Plasma
A comparison of two RP-high-performance liquid chromatography (HPLC) methods to determine efficient sample extraction to determine efficient method for getting optimum retention time and recovery of verapamil from rat plasma.
متن کاملThe Lipophilicity Examination of Some ACE inhibitors and Hydrochlorothiazide on Cellulose in RP Thin-Layer Chromatography
In this assay, the evaluation of lipophilicity of four ACE-inhibitors and hydrochlorothiazide (HCTZ) with RP-TLC on cellulose layers was described using three binary solvent systems. The selected ACE inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with HCTZ. In addition, the linea...
