Development and Validation of a Quantitative Analysis of Water-Soluble Vitamins Using High-Performance Thin-Layer Chromatography and Its Application to the Analysis of Nutraceuticals
In this study, a high-performance thin-layer chromatography (HPTLC)-based method was developed for the quantification of five water-soluble vitamins, B2, B3, B6, B12, and C, using ethanol–water (70:30, v/v) as the mobile phase. The method was validated according to the International Conference on Harmonisation (ICH) guidelines and the limits of detection/limits of quantification were determined as 5.27/15.97 ng (Vitamin B2), 13.03/39.47 ng (Vitamin B3), 59.61/180.64 ng (Vitamin B6), 14.17/42.93 ng (Vitamin B12), and 119.27/361.42 ng (Vitamin C) per band, respectively. The usefulness of the validated method for quality control was demonstrated with the successful quantitative analysis of the five vitamins in a range of nutraceuticals.
期刊介绍：
Separations (formerly Chromatography, ISSN 2227-9075, CODEN: CHROBV) provides an advanced forum for separation and purification science and technology in all areas of chemical, biological and physical science. It publishes reviews, regular research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal:
Manuscripts regarding research proposals and research ideas will be particularly welcomed.
Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
Manuscripts concerning summaries and surveys on research cooperation and projects (that are funded by national governments) to give information for a broad field of users.
The scope of the journal includes but is not limited to:
Theory and methodology (theory of separation methods, sample preparation, instrumental and column developments, new separation methodologies, etc.)
Equipment and techniques, novel hyphenated analytical solutions (significantly extended by their combination with spectroscopic methods and in particular, mass spectrometry)
Novel analysis approaches and applications to solve analytical challenges which utilize chromatographic separations as a key step in the overall solution
Computational modelling of separations for the purpose of fundamental understanding and/or chromatographic optimization
