Volatile oil is an important natural fragrance, widely used in medicine, daily chemicals, flavors and fragrances and other industries. The general gas chromatography detection method is suitable for the determination of eucalyptol content in medicinal materials and Chinese patent medicines with less complex ingredients. The composition of volatile oils from medicinal materials is complex. Our company uses a gas chromatography internal standard determination method to detect the eucalyptol content in medicinal materials. The use of homogenate crushing and reflux extraction effectively prevents the volatilization of eucalyptol in magnolia medicinal materials and ensures the authenticity and accuracy of the measurement results. . Chromatographic conditions
Use capillary chromatographic column
Nitrogen as carrier gas, pre-column pressure
Vaporization chamber temperature ℃
Detector temperature ℃
Column temperature ℃ is retained, expressed in ℃/ The rate rises to ℃, and the content of eucalyptol is measured on a flame ionization detector using styrene as the internal standard.
Calculate the content of eucalyptol based on the qualitative retention time of the reference substance and the peak area ratio. The results have a good linear relationship with the injection amount of eucalyptol (the average recovery rate of standard addition is, ).
