Determination of cholesterol using o-phthalaldehyde

Open access
Rudel, L.L., Morris, M.D.·1973·Journal of Lipid Research

Abstract

A simple, rapid method for the determination of cholesterol in plasma and tissue using o-phthalaldehyde is presented. Comparison of this method with the FeCl(3) method gave identical results. However, the o-phthalaldehyde determination is three times more sensitive than the FeCl(3) determination (molar extinction coefficients of 11,610 and 33,440 for FeCl(3) and o-phthalaldehyde, respectively), it takes less time to complete, and the color developed is more stable. The o-phthalaldehyde method can be used to assay free and esterified cholesterol directly after thin-layer chromatographic separation.

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.
