Abstract

Hydrophilic interaction liquid chromatography (HILIC) method using internal standard for the determination and stability study of ascorbic acid was developed. HILIC method was very fast and simple using the following analytical conditions: ZIC HILIC (150 x 2.1 mm, 3.5 microm) chromatographic column and mobile phase composed of ACN and 50 mM ammonium acetate buffer pH 6.8 (78:22 v/v). Diode array detection was performed and chromatograms were processed at 268 nm, the maximum wavelength of absorbance of ascorbic acid. An extensive stability study of ascorbic acid as a function of various factors including temperature, stabilizing agents, oxygen presence and its concentration in solution was performed in order to gain information about the quantitative influence of individual stability factors. Low temperature and stabilizing agents (o-phosphoric acid and oxalic acid) were found to be key factors enabling substantial enhancement of the stability of ascorbic acid.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Internal standard quantification of L-ascorbic acid in biological material is difficult because it is difficult to find a compound suitable for both extraction and analysis steps similar to L-ascorbic acid.

    “An internal standard is not routinely used to determine L-ascorbic acid in biological material because it is difficult to find a compound that is suitable for both extraction and analysis steps similar to L-ascorbic acid.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
