Muscone Content was Measured by Ultrasonic Extraction/Mass Spectrometry in Musk

Muscone content was quickly measured by gas chromatography/ flame ionization detector(GC/FID) in musk..Samples were extracted by ethanol-ultrasonic,and filtered,directly determined by GC/ FID,Recovery rate of Muscone was more than 95% in experiment,quantify was limited 0.80 μg·mL-1;calibration curve linear range was 0-320 μg·mL-1,Linear correlation coefficient(r) was 0.9995;Peak area RSD of which three high-lever,medium,low concentration respectively were 50,150,300μg·mL-1 were respectively determined 1.08、0.89、0.55.The result was showed that Muscone content was determined by ethanol-ultrasonic extraction and GC/FID was a simple,rapid,accurate method.
