[0038] The preparation method of Chuanxiong essential oil of the present invention comprises steam distillation extraction and carbon dioxide supercritical extraction.
[0039] Rhizoma Chuanxiong essential oil of the present invention is detected by gas chromatography-mass spectrometry instrument, and its component ratio by mass percentage is: trans-ligustilide (trans-ligustilide) (>25%), β-cineole ( β-eudesmene) (>5%), senkyunolide (>6%), butylphthalide (>4%).
Embodiment 1
[0041] Take 100Kg of dried rhizomes of Ligusticum chuanxiong Hort., pile them up for 2 days, crush them to 50 mesh coarse particles, soak the coarse particles in 8 times the mass of hydrochloric acid aqueous solution with a pH value of 5.0, and extract overnight. 0.8% cellulase and 0.3% pectinase were added to the extraction mixture by mass percentage, and enzymolysis was carried out at 37° C. for 2.5 hours. Put the above sample and its mixture into a steam distillation extraction apparatus, reflux extraction at 110°C for 7 hours, collect the distillate, cool it to room temperature, and place it in an oil-water separator for separation. The oil layer was dried with anhydrous sodium sulfate and separated to obtain the essential oil of Ligusticum chuanxiong.
Embodiment 2
[0043] Take 50Kg of dried rhizomes of Ligusticum chuanxiong Hort., pile them up for 2 days, crush them to 50 mesh coarse particles, soak the coarse particles in 8 times the mass of hydrochloric acid aqueous solution with a pH value of 5.0, and extract overnight. 0.8% cellulase and 0.3% pectinase were added to the extraction mixture by mass percentage, and enzymolysis was carried out at 37° C. for 2.5 hours. Put the above sample and its mixed solution into a carbon dioxide supercritical extraction instrument. The extraction temperature is 46°C, the pressure is 15.70MPa, the time is 85min, and the flow rate of carbon dioxide is 30kg / h; the essential oil is collected and refined in a molecular distillation instrument. The feed temperature was 43°C, the sample injection speed was 510mL / h, the first stage evaporation temperature was 112°C, and the second stage evaporation temperature was 63°C, and the second stage distillation part was collected to obtain Chuanxiong essential oil. ...
