The distribution behavior of ofloxacin enantiomers was examined in the aqueous and organic solvent of a two-phase system containing chiral selector L-tartarate. The effect of extraction equilibrium time, buffer pH, organic solvents and length of alkyl chain of L-tartarate on the partition coefficients and enantioselectivity of racemic ofloxacin were investigated, respectively. The L-tartara...

In the crystal structure of the title compound, C(8)H(20)N(+)·C(4)H(5)O(6) (-)·2H(2)O, the ions and water mol-ecules are linked via O-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).

Distribution behavior of mandelic acid enantiomers was examined in an aqueous-organic solvent of a two-phase system containing L-tartarate. The influences of pH, length of alkyl chain of Ltartarate, organic solvent, concentration of phosphate salt and time of chiral extraction on partition coefficient (k) and separation factor (α) were investigated, respectively. With the rise of pH, k decrease...

A simple, accurate and precise high-performance thin-layer chromatographic method has been developed for the estimation of Atorvastatin Calcium and Metoprolol Tartarate simultaneously from a capsule dosage form. The method employed Silica gel 60F (254s)precoated plates as stationary phase and a mixture of Chloroform: Methanol: Glacial acetic acid (dil.) :: (9:1.5:0.2 ml %v/v) as mobile phase. D...

Background & Aims: Despite 20 years of research, there is no compelling evidence about the effect of carnitine supplementation on improving physical performance in healthy subjects. The aim of this study was to determine the effect of long term consumption of acute L-carnitine L-tartarate (LCLT) on fat metabolism and aerobic capacity. Methods: A total of 28 healthy nonathlete male students rece...

Background: The benefit effect of L-carnitine is proposed for treatment of obesity as long time periods. So, in the present study, effect of L-carnitine on serum FSH, LH and testosterone levels in adult male rats is evaluated. Materials and Methods: Rats were treated different doses of L-carnitine tartarate daily for 16 days, peritoneally. The control group was treated saline as vehicle. After ...

A simple and accurate reverse phase liquid chromatographic method was developed for the determination of related substances, degradants and assay of Tolterodine Tartarate active pharmaceutical ingredient used in the treatment of urinary incontinence. A HPLC method was developed for the separation of related substances, degradants obtained from samples generated after stress degradation and also...
