Problems solved by technology

Schisandra extracts mostly use water extraction and alcohol extraction. The disadvantage is that the extraction time is long, generally 2-3 times, and each extraction is 1.5-2 hours, which wastes water, electricity and steam energy, resulting in high cost and low yield, generally 8%. about

Embodiment

[0016] 1. Take 10 kg of Schisandra chinensis. The schisandra chinensis was selected by winnowing, impurities removed, washed, dried, crushed, and sieved through a 120-mesh sieve to obtain about 9.8 kg of schisandra dry powder.

[0017] 2. Soak the sifted schisandra with 4-6 times the amount of 60-75% edible ethanol solution for 30 minutes, and heat to 70-85°C.

[0018] 3. Microwave treatment: treat the heated solution with a microwave generator for 20 minutes.

[0019] 4. Reflux extraction: The solution after microwave treatment is kept at 70-85°C for 20 minutes.

[0020] 5. Filtration: The extracted solution is filtered.

[0021] 6. High-speed centrifugation: centrifuge at 3000 rpm for 10 minutes with a high-speed centrifuge, and take the supernatant.

[0022] 7. Vacuum drying: heat and dry the centrifuged solution in a vacuum dryer to obtain about 0.93 kg of extract.

The present invention has the features of high extraction rate, high production efficiency and high product quality.

Description

technical field [0001] The invention relates to a method for extracting Chinese medicinal materials, in particular to a method for extracting active components of Schisandra chinensis. Background technique [0002] In the prior art, schisandra powder is suitable for food and medicine. The extraction method of Schisandra chinensis mostly adopts water extraction and alcohol extraction. The disadvantage is that the extraction time is long, generally 2-3 times, and each extraction is 1.5-2 hours, which wastes water, electricity and steam energy, resulting in high cost and low yield, generally 8%. about. Contents of the invention [0003] The object of the present invention is to provide an advanced and reasonable extraction method for active components of Schisandra chinensis aimed at the above-mentioned deficiencies. [0004] Technical solution of the present invention: the active ingredient extraction method of Schisandra chinensis is: [0005] 1. Selection: Select Schisa...
