HPLC Separation of Hydrocortisone and Hydrocortisone's Degradation Products
Cortisol (hydrocortisone) is a steroid hormone produced by the adrenal gland. Hydrocortisone is a hydrophobic neutral compound with some polar groups in its structure. Several Primesep mixed-mode columns were used for separation of hydrocortisone and its degradation products. Each column showed a different selectivity for separation, which attributed to different polar-embedded groups on Primesep 100 and Primesep D columns. Both columns can be used for degradation studies of various hydrophobic compounds.
USP Methods for the Analysis of Hydrocortisone on a Legacy L1 Column
Application Notes: Hydrocortisone is a naturally occurring hormone released during times of stress. Hydrocortisone has been synthesized and is used to treat diseases such as allergic reactions and skin conditions. According to the USP methods, hydrocortisone contains not less than 97 percent and not more than 102 percent of hydrocortisone calculated on the dried basis. The USP HPLC method for the separation of hydrocortisone was developed on Legacy L1 column according to the US Pharmacopeia methodology. L1 classification is assigned to reversed-phase HPLC column containing C18 ligand. Support for the material is spherical silica gel with particles size 3-10 um and pore size of 100-120A.
Hydrocortisone is the drug form of the steroid hormone cortisol. Cortisol is an important biological molecule which affects blood sugar, metabolism and the immune system. It was retained on the reverse-phase column Legacy L1. Comparisons of Legacy L1 and Phenomenex columns are available by request.
Hydrocortisone, also known as 11β,17α,21-trihydroxypregn-4-ene-3,20-dione, is a corticosteroid, is similar to a natural hormone produced by your adrenal glands. It is used to treat certain forms of arthritis as well various skin conditions (redness, swelling, and itching). Primesep 200, a reverse phase column, contains embedded acidic ionizable groups and can retain Hydrocortisone. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
