Prepare a test solution by shaking a portion of Oral Suspension with a mixture of acetone and 0.1 N hydrochloric acid (4:1) to obtain a solution containing about 1 mg of amoxicillin per mL. Prepare a Standard solution of USP Amoxicillin RS in 0.1 N hydrochloric acid containing 1 mg per mL. Use within 10 minutes after preparation. Apply separately 5 µL of each solution on a thin-layer chromatographic plate coated with a 0.25-mm layer of chromatographic silica gel mixture (see Chromatography 〈621〉). Place the plate in a suitable chromatographic chamber, and develop the chromatogram in a solvent system consisting of a mixture of methanol, chloroform, water, and pyridine (90:80:30:10). When the solvent front has moved about three-fourths of the length of the plate, remove the plate from the chamber, and dry with warm air for 10 minutes. Locate the spots on the plate by spraying lightly with a solution of ninhydrin in alcohol containing 3 mg per mL, and dry at 110° for 15 minutes: the R_F value of the principal spot obtained from the test solution corresponds to that obtained from the Standard solution.

A: Triturate a quantity of the contents of Capsules, equivalent to about 500 mg of theophylline, with 10-mL and 5-mL portions of solvent hexane, and discard the solvent hexane. Triturate the residue with two 10-mL portions of a mixture of equal volumes of 6 N ammonium hydroxide and water, and filter each time. Evaporate the combined filtrates to about 5 mL, neutralize, if necessary, with 6 N acetic acid, using litmus, and then cool to about 15°, with stirring. Collect the precipitate on a filter, wash it with cold water, and dry at 105° for 2 hours: the theophylline so obtained melts between 270° and 274° (see Melting Range or Temperature 〈741〉, Procedures, Procedure for Class I). Retain the remaining portion of the theophylline for use in Identification test B.
