Rape pollen has always been considered as a research hotspot in health foods and pharmaceuticals due to its abundance of natural active ingredients. In this work, compound with antioxidant activity was directly isolated from the methanol extract rape using two-step procedure, under supervision online HPLC−1,1-diphenyl-2-picrylhydrazyl (HPLC-DPPH) detection. Firstly, HPLC−DPPH detection used ide...

Abstract A homochiral metal–organic framework (MOF) comprising [Co(L)(bpe)2(H2O)2]·H2O was prepared using (1R,2R)-(−)-1,2-cyclohexanedicarboxylic acid (H2L) and 1,2-bis(4-pyridyl)-ethylene as organic ligands. The MOF explored chiral stationary phase (CSP) for high-performance liquid chromatography (HPLC) separation of racemates. Nine racemates including naphthol, alcohol, diol, amine, ketone, e...

zataria multiflora boiss is used in traditional folk remedies as antiseptic, analgesic, carminative, anthelmintic medication. the main components of zataria multiflora are phenolic compounds such as thymol and carvacrol. the aim of this study was developed a simple and rapid method for determination of the thymol in different extracts of zataria multiflora by hplc method. the dried aerial parts...

a sensitive high performance liquid chromathography (hplc) analytical procedure was developed for the quantitive determination of trimethoprim (tm* and sulphamethoxazole (sm) in commercial dosage forms. c18 analytical column (stainless steel, 25 cm * 4.6 mm i.d.) was packed with 5-*m particles of the reversed phase material and used for assays. mobile phase containing 0.025 m sodium phosphate a...

BACKGROUND & OBJECTIVES Simple and reliable methods to estimate drugs in pharmaceutical products are needed. In most cases, antiretroviral drug estimations are performed using a HPLC method, requiring expensive equipment and trained technicians. A relatively simple and accurate method to estimate antiretroviral drugs in pharmaceutical preparations is by spectrophotometric method, which is cheap...

X-linked diseases, this requires the equimolar mixing of PCR products between a wild-type DNA sample and the sample to be tested. (c) The type of mutations searched for must be detectable by D-HPLC. D-HPLC is more sensitive in the screening of point mutations, which is the case of most FIX mutations (1 ). In any case, once the D-HPLC conditions have been defined, a prospective study of a novel ...
