The RP-HPLC analysis of anthocyanins

Chromatographia, 1998
Conditions were determined for the separation of a complex set of anthocyanins (free aglycones, mono- and multiglycosides and esterified forms) by HPLC. The optimised gradient elution method was then used to carry out qualitative and quantitative analysis of anthocyanin compounds present in the callus tissue ofRudbeckia hirta L. and the tubular flowers

Analysis of Invertebrate Neuropeptides by RP-HPLC

Journal of Liquid Chromatography, 1983
Abstract The application of reverse phase-high performance liquid chromatography to the analysis of four synthetic invertebrate neuropeptides is described. Proctolin (Arg-Try-Leu-Pro-Thr), locust adipokinetic hormone (p-Glu-Leu-Asn-Phe-Thr-Pro-Asn-Trp-Gly-Thr-NH2), crustacean erythrophore concentrating hormone (p-Glu-Leu-Asn-Phe-Ser-Pro-Gly-Trp-NH2 ...

RP-HPLC ANALYSIS OF HYDROPHOBIC ALENDRONATE AMIDATED DERIVATIVES

Journal of Liquid Chromatography & Related Technologies, 2010
The reversed phase high performance liquid chromatography (RP-HPLC) was evaluated for its application in the analysis of the quantiation of the alendronate derivatives. The anti-phase Agilent CLC-ODS C18 column was used at the temperature of 50°C. The RP-HPLC trace was monitored with a differential refractive index detector for the lack of ultraviolet (

Multivariate Analysis of Perampanel in Pharmaceutical Formulations Using RP-HPLC

Chromatographia, 2020
A new, sensitive, robust RP-HPLC method was developed using quality by design (QbD) approach for the determination of perampanel in pharmaceutical tablets. Screening of five independent factors; concentration and pH of the phosphate buffer, temperature, flow rate and % of the aqueous part of mobile phase; was performed by a fractional factorial design (

Quantitative Analysis of Quercetin in Euphorbia helioscopia L by RP-HPLC

Cell Biochemistry and Biophysics, 2011
Euphorbia helioscopia L is widespread in China and has a large number of flavonoids. Quercetin glycosides, having useful biological activities, are abundant in this plant, and no validated analytical method has so far been developed for their determination.

[Analysis of phenylethanoid glycosides of Herba cistanchis by RP-HPLC].

Yao xue xue bao = Acta pharmaceutica Sinica, 2001
The Chinese drug "Rou Cong-rong" (Herba Cistanchis) is one of the commonly used drugs in Chinese traditional medicine. It is used to reinforce the vital function of kidney, especially that of the sexual organs and induce laxation, for the treatment of impotence, premature ejaculation in men, infertility, morbid leukorrhea, profuse metrorrhagia in women,

Quantitative Analysis of Orotic Acid in Urine by RP-HPLC

Nucleosides and Nucleotides, 1990
Abstract we describe a new RP-HPLC assay to measure orotate concentration in urine. The method is rapid, sensitive and precise. It is particularly suitable for the diagnosis of inherited metabolic diseases and deranged orotate metabolism.
