摘要
New procedures are described for the determination of the free salicylic acid content and the total nonaspirin salicylate content of buffered aspirin tablets. Free salicylic acid and total nonaspirin salicylate contents of a number of tablet samples were determined. The new procedure for nonaspirin salicylates yielded results which were in close agreement with those found using the Levine and Weber method. No relationship was found between the free salicylic acid content and the total nonaspirin salicylate content of buffered tablets. The USP XVII test method for free salicylic acid yielded results which were consistently and significantly lower than those found with the other methods studied.
