Embodiment 1
[0015] Weigh 330g of ferulae ferulae root, pulverize it, and add it to a supercritical carbon dioxide extractor. Firstly, use carbon dioxide for the first extraction. Extraction pressure: 15Mpa, extraction temperature: 50°C, extraction time: 3.5 hours, separation pressure: 4.0Mpa, separation temperature: 30°C, after the extraction is completed, collect the extract in the separator, and after drying, extract I is 13.9 grams, with an extraction rate of 4.2%. The main component of extract I is guaiacol. Matter I was left at room temperature for 7 days, then filtered to obtain guaiacol crystals;
[0016] Then the remaining slag is extracted for the second time with carbon dioxide and carrier ethanol (volume ratio 10:1), extraction pressure: 25MPa, extraction temperature: 50°C, separation pressure: 4.5MPa, separation temperature: 30°C, extraction time : 4 hours, after extraction, collect the extract in the separator, get extract 18.7g after decompression distillation ethanol, yield...
Embodiment 2
[0018] Weigh 350g of ferulae ferulae root, pulverize it, and add it to a supercritical carbon dioxide extractor. Firstly, use carbon dioxide for the first extraction. Extraction pressure: 10Mpa, extraction temperature: 40°C, extraction time: 3.5 hours, separation pressure: 3.0Mpa, separation temperature: 40°C, after the extraction is completed, collect the extract in the separator, and dry it to obtain 13.7 grams of the extract, with an extraction rate of 3.9%, wherein the main component of the extract I is guaiacol, the extract I After standing at room temperature for 7 days, filter to obtain guaiacol crystals;
[0019] Then the remaining slag is extracted for the second time with carbon dioxide and carrier ethanol (volume ratio 100:5), extraction pressure: 30MPa, extraction temperature: 40°C, separation pressure: 7.8MPa, separation temperature: 40°C, extraction time : 4 hours, after the extraction is complete, collect the extract in the separator, obtain extract 19.3g after ...
Embodiment 3
[0021] Take by weighing 342g of Ferulicum ferulae root, through pulverization, join in the supercritical carbon dioxide extractor, at first carry out the first extraction with carbon dioxide. Extraction pressure: 20MPa, extraction temperature: 45°C, extraction time: 4 hours, separation pressure: 4.0MPa, separation temperature: 30°C. After the extraction was completed, the extract in the separator was collected and dried to obtain 15.3 grams of the extract, with an extraction rate of 4.4%, wherein the main component of the extract I was guaiacol, and the extract I was placed at room temperature for 7 days before being filtered. Obtain guaiacol crystals;
[0022] Then the remaining slag is extracted for the second time with carbon dioxide and carrier acetone (volume ratio 100:5), extraction pressure: 40MPa, extraction temperature: 45°C, separation pressure: 4.5MPa, separation temperature: 35°C, extraction time : 4 hours, after extraction, collect the extract in the separator, g...
