Embodiment 1
[0059] Embodiment 1: Pre-experiment
[0060] This embodiment adopts different extracting methods to extract the volatile oil of S. chinensis respectively, specifically as follows:
[0061] 1. Steam distillation method:
[0062] (1) Get 600g of dry Saikui powder and grind it into a distillation flask, add 1000g of distilled water and carry out steam distillation, the extraction time of distillation is 5h, to obtain a water system containing volatile oil;
[0063] (2) Add ether to the water system containing volatile oil for extraction, discard the separated water layer, add anhydrous sodium sulfate to the ether solution containing volatile oil for dehydration, filter and recover ether to obtain dry and pure volatile oil.
[0064] 2. Simultaneous distillation extraction method:
[0065] Weigh 600g of dried Saikui powder and grind it into a distillation flask, add 1000g of distilled water, and measure ether in the distillation flask at the same time, connect the simultaneous d...
Embodiment 2
[0072] Embodiment 2: the method for extracting and purifying the volatile oil of Sai Kui
[0073] (1) Take 500g of fresh sunflower, wash and dry it, then grind it to a particle size of 60 mesh, add 1000g of distilled water, stir and carry out steam distillation, and the distillation extraction time is 5 hours to obtain a water system containing volatile oil;
[0074] (2) Add diethyl ether to the water system containing volatile oil for extraction, discard the separated water layer, add anhydrous sodium sulfate to the diethyl ether solution containing volatile oil for dehydration, filter and recover diethyl ether to obtain dry and pure volatile oil; the extraction rate is 0.41% , the water content in the volatile oil is 0.65%.
