Abstract

Abstract: A simple and sensitive gas chromatography with tandem mass spectrometry method was developed and validated for the simultaneous determination of borneol and muscone in rat plasma. The analytes and internal standard, naphthalene, were extracted using a convenient one‐step liquid–liquid extraction method with ethyl acetate. The chromatographic separation was realized on a HP‐5MS capillary column and detected in multiple reaction monitoring mode. Excellent linearity ( R 2 ≥ 0.996) was shown over 10.0–5000 ng/mL for borneol and 2.5–250 ng/mL for muscone. The lower limit of quantitation was 10 and 2.5 ng/mL for borneol and muscone, respectively. The intra‐ and interday precisions were less than 7.52%, and the accuracy values were between −8.03 and 14.52%. The extraction recovery, matrix effect, and stability were sufficient to meet the Food and Drug Administration criteria. Meanwhile, the assay was successfully applied to the preclinical pharmacokinetic study of borneol and muscone following intravenous administration of Xingnaojing injection, a modern Chinese herbal medicine preparation.
