Identification— Transfer a quantity of Ointment, equivalent to about 5 mg of hydrocortisone acetate, to a flask, add 5 mL of methanol, and heat on a steam bath for 5 minutes with frequent mixing. Cool to solidify the ointment base, and filter. Using the filtrate as the test solution, proceed as directed under Thin-layer Chromatographic Identification Test 201. Locate the spots by spraying the dried plate with a 70% methanolic sulfuric acid solution. Heat the plate for 20 to 30 minutes at 90, allow to cool, and view under long-wavelength UV light: the RF value and fluorescence of the principal spot obtained from the test solution correspond to those obtained from the Standard solution.
