摘要:

An NMR procedure is described for the quantitative determination of methylsalicylate as a drug entity and in wintergreen oil. For standard mixtures containing the pure drug a mean result of 99.9 ± 0.75% w/w was obtained. Analysis of a wintergreen oil sample for its contents of methyl-salicylate gave a mean result of 99.2 ± 0.17% w/w. The results are compared with those obtained using the official procedure.
