Embodiment 1
[0048] 1) steam distillation
[0049] Get Xinjiang Ligusticum edulis pulverizes, after No. 3 sieves, obtain Xinjiang Ligusticum edulis coarse powder 1.5 kilograms, according to the ratio of material-liquid ratio 1: 5 (weight ratio) after Xinjiang Ligusticum edulis and water are mixed, cold soaking process 6 hours, Then place it in a steam distillation device and distill for 6 hours until no volatile oil condenses and sinks. After the volatile oil is separated with a separatory funnel, the lower layer essential oil is combined to obtain 18.3 grams, and the yield is 1.2%. See results Figure 5 and table1;
[0050] Among them, GC-MS analysis conditions: AI / AS 3000 Trace GC 2000 DSQ gas chromatography mass spectrometer; DB-1701 capillary column (30m×0.25mm, film thickness 0.25μm); heating program: initial temperature 40°C, hold for 1 minute , 10°C / min to 200°C, hold for 10 minutes; inlet temperature 200°C, 40°C; injection volume 1μl, split ratio 100:1; ion source temperature 250...
