Accelerated Stability and Chemical Kinetics of Ethanol Extracts of Fruit of Piper sarmentosum Using High Performance Liquid Chromatography
The extracts of Piper sarmentosum, a medicinal plant, are being used to prepare phytopharmaceuticals while the information about chemical kinetics of constituents of the extract is unavailable to assign precise shelf life (t90) and find optimum storage conditions of the product for patient safety, and to avoid economic repercussions of launching an unstable product. The extract was exposed to t...

متن کاملDetermination of steroids adulterated in liquid herbal medicines using QuEChERS sample preparation and high-performance liquid chromatography.
QuEChERS sample preparation was optimized using solvent extraction with acetonitrile and dispersive-solid phase extraction with primary and secondary amine sorbents, and validated for high-performance liquid chromatographic determination of nine steroids commonly used to adulterate herbal medicines: such as triamcinolone, prednisolone, hydrocortisone, methylprednisolone, betamethasone, dexameth...
متن کاملEnantiomeric Separation and Circular Dichroism Detection of Metalaxyl Acid Metabolite by Chiral High Performance Liquid Chromatography
The enantiomers of metalaxyl acid metabolite (MX-acid) were separated by HPLC using cellulose-tris-(3,5-dimethylphenyl-carbamate) (CDMPC) as chiral stationary phase. The effects of mobile phase composition, flow rate and column temperature on the resolution were investigated and good separation was achieved with n-hexane/2-propanol/trifluoroacetic acid as mobile phase. The circular dichroisms d...
متن کاملHigh-Performance Liquid Chromatography Determination of Methotrexate in Plasma
This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...
