Embodiment 1
[0023] Example 1: Extracting amygdalin from bitter almonds by gas explosion
[0024] Add bitter almonds, a medicinal plant rich in fats and oils, to water at a ratio of 1:1 of dry medicinal materials to water, and then soak them at room temperature for 30 minutes; place the soaked materials in a steam explosion tank, and put them into Air to make the temperature in the tank reach 100°C, keep it for 5 minutes, and then carry out steam explosion treatment; collect the materials after steam explosion, extract amygdalin in bitter almonds before and after steam explosion, and use silver nitrate titration method to determine the content of bitter almonds, after steam explosion The amygdalin extraction rate of the material is 15.32% higher than that of the unexploded material.
Embodiment 2
[0025] Example 2: Gas explosion treatment for the extraction of chlorinated limpetine
[0026] Chop the double-sided needle medicinal material into 3-5cm pieces, add water according to the ratio of 1:1 of the absolute dry medicinal material and water, and then soak at room temperature for 60 minutes; put the soaked material in the steam explosion tank , put in water vapor to make the temperature in the tank reach 200°C, keep it for 5 minutes, and then carry out steam explosion treatment; add an organic solvent 6 times its dry weight to the material after steam explosion treatment, and extract 3 times under boiling state, each time 3.0h , combined the extracts; the extracts were evaporated under reduced pressure to obtain a precipitate, which was mixed with HCl solution of pH 2, extracted with ethyl acetate to remove non-alkaline components, and then the aqueous phase was adjusted to pH 10 with NaOH, while Precipitation is generated, remove the precipitate and extract the remai...
Embodiment 3
[0027] Example 3: Chlorogenic acid extracted from leaves of Eucommia ulmoides treated by gas explosion
[0028]Get 500g of eucommia leaf medicinal material, add acetic acid water (the ratio of acetic acid to water is 1:100) to eucommia leaf medicinal material according to the ratio of dry medicinal material and acetic acid water quality 1:2, then soak at normal temperature for 60min; The final material is placed in the steam explosion tank, and carbon dioxide is introduced to make the temperature in the tank reach 80°C, and the steam explosion treatment is carried out after maintaining for 15 minutes; the material after steam explosion treatment or the conventionally crushed material to 40 mesh is added to 5 times its absolute dry weight extracted water at 40°C for 3 times, each time for 50 min, and combined the extracts; concentrated the extracts under reduced pressure, added 3 times more ethyl acetate to the concentrated solution and extracted twice to obtain an ethyl acetate...
