Embodiment 1

[0052] The preparation of embodiment 1 pig bone extract

[0053] Stripping: Take fresh or frozen pig limb bones, remove the flesh and fascia, cut off, remove the bone marrow, and obtain 15kg of clean bones.

[0054] Extraction: Take the clean bone, add 4 times the weight of purified water, extract under hot pressure at 121°C and 0.12Mpa for 2 hours, filter to obtain the filtrate, and after the filtrate stands still at 5°C for 12 hours, remove the upper layer of oil from the extract, Use 8% sodium hydroxide solution to adjust the pH to 8.5, heat to about 45°C, add trypsin according to 0.2% of the bone weight, after constant temperature continuous hydrolysis for 2 hours, adjust the pH to 3.5 with 12% hydrochloric acid, boil, and keep warm for 30 minutes Filter and adjust the pH of the filtrate to 6.5 with 8% sodium hydroxide solution. Add activated carbon according to 0.1% of the volume of the filtrate, heat to boiling, keep warm for 15 minutes and then filter. The filtrate is ...

Embodiment 2

[0057] The preparation of embodiment 2 deer bone extract

[0058] Stripping: Take fresh or frozen sika deer limb bones, remove flesh and fascia, cut off, remove bone marrow, and obtain 15kg of clean bones.

[0059] Extraction: Take the clean bone, add 3 times the weight of purified water, extract under hot pressure at 121°C and 0.12Mpa for 2 hours, filter to obtain the filtrate, and then remove the upper layer of oil from the extract after standing still at 4°C for 12 hours. Use 8% sodium hydroxide solution to adjust the pH to 9.0, heat to about 45°C, add trypsin according to 0.2% of the bone weight, continue hydrolysis at constant temperature for 2 hours, adjust the pH to 4.0 with 12% hydrochloric acid, boil, and keep warm for 30 minutes Filter and adjust the pH of the filtrate to 7.0 with 8% sodium hydroxide solution. Add activated carbon according to 0.1% of the volume of the filtrate, heat to boiling, keep warm for 15 minutes and then filter. The filtrate is frozen at -20...

Embodiment 3

[0062] The preparation of embodiment 3 melon seed extract

[0063] Washing: Take the mature and dried melon seeds, rinse them with purified water for 4 times, dry the water, pick out the sundries, and get 15kg of clean melon seeds.

[0064] Extraction: Take clean melon seeds, add 2 times the weight of purified water, extract at 121°C, 0.12MPA hot press for 2 hours, filter to obtain the filtrate, then add 2 times the weight of purified water, repeat the last extraction, and repeat the extraction three times. The three filtrates were combined, cooled to 30°C, and the pH of the above filtrate was adjusted to 3.5 with 12% hydrochloric acid, and stood still for 12 hours.

[0065] Remove miscellaneous proteins, boil the above hydrolyzate, keep it warm for 30 minutes, filter it, adjust the pH of the above filtrate to 8.5 with 8% sodium hydroxide solution, freeze it at -20°C for 48 hours, then melt it at room temperature, boil it, and keep it warm for 30 minutes Filter and adjust the...

Abstract

The invention provides a drug of bone-melon extract for injection, mammalian bone peptides and melon seed peptides are extracted, the obtained extracts are mixed according a certain proportion, thus preparing the drug for injection. The invention adopts a special extraction technology to increase the active ingredients, the extraction efficiency is high, and the substances with high molecular weight are reduced to the minimum. The drug of the invention has the effects of regulating bone metabolism, stimulating proliferation of osteoblasts, promoting formation of new bones, regulating calcium and phosphorus metabolism, increasing bone calcium deposition and preventing osteoporosis, thus being used for prevention and treatment for rheumatism, rheumatoid arthritis, osteoarthritis, lumbar and leg pain, fracture trauma repair and other diseases.

Description

technical field [0001] The invention relates to a polypeptide pharmaceutical composition, in particular to a medicine for injection of the extract of bone melon, and also relates to a preparation method of the medicine. Background technique [0002] Bone melon extract contains a variety of active polypeptides and free amino acids, which can regulate bone metabolism, stimulate osteoblast proliferation, promote new bone formation, regulate calcium and phosphorus metabolism, increase bone calcium deposition, and prevent osteoporosis. [0003] The role of osteoinductive polypeptide biological factors: osteoinductive polypeptide biological factors can effectively promote the synthesis of bone formation and absorption and bone-derived growth factors in the body, including bone morphogenetic proteins (BMPs), β-transforming growth factor (TGF -β), fibroblast growth factor (FGF), etc., which have a variety of biological activities. Its main pharmacological effects are: promoting cel...
