Embodiment 1

[0008] Weigh 1Kg of sweet-scented clover, crush it into coarse powder, add organic solvent ethyl acetate, heat and reflux in 80°C water bath to extract 3 times, each time for about 1.5 hours, and combine the filtrate; after concentrating the filtrate, dry it in an oven at 60°C to obtain the grass 34g of sweet-scented osmanthus extract (the contents of polyphenols, flavonoids and coumarins in the extract are 3.2%, 1.2%, and 5.3%, respectively). Drug efficacy experiments have shown that the ethyl acetate extract of sweet clover has very good analgesic, anti-inflammatory and hemostatic effects. Anti-inflammatory experiments showed that when 240mg / Kg of drugs were applied to the xylene-induced mouse ear swelling model (the following drugs were calculated based on the amount of extract extract), it could significantly reduce the xylene-induced mouse ear swelling (P<0.01 ); application of 120mg / Kg of the drug can significantly reduce xylene-induced mouse auricle swelling (P<0.05). ...

Embodiment 2

[0010] Weigh Melilotus 1Kg, crush it into a coarse powder, add an appropriate amount of solvent ethyl acetate to ultrasonically extract 3 times, each time about 0.5h, and combine the filtrate; after concentrating the filtrate, dry it in a 60°C oven to obtain 43g of Melilotus extract ( The contents of polyphenols, flavonoids and coumarins in the extract are 3.4%, 1.6%, 5.8%, respectively). It can be made into various types of preparations with auxiliary materials, and the finished products of this extract also have strong analgesic, anti-inflammatory, and hemostatic effects. Anti-inflammatory experiments showed that when 240mg / Kg of xylene-induced mouse ear swelling model was applied, it could significantly reduce xylene-induced mouse ear swelling (P<0.01); Toluene induced ear swelling in mice (P<0.05). Analgesic experiments showed that when the drug was applied at 120mg / Kg, the number of writhing in mice could be significantly reduced (P<0.01); when the drug at 60mg / Kg was ap...

Embodiment 3

[0012] Weigh 1Kg of sweet-scented osmanthus, crush it into coarse powder, add organic solvent ethanol in a water bath at 80°C, reflux extract 3 times, about 1.5 hours each time, combine the filtrate; concentrate the filtrate and dry it in an oven at 60°C to obtain sweet-scented sweet-scented osmanthus 52g of the extract (the contents of polyphenols, flavonoids and coumarins in the extract are 2.2%, 3.8%, and 0.97%, respectively). It is made into tablets with auxiliary materials. Drug efficacy experiments show that the ethanol extract of sweet clover has very good analgesic and hemostatic effects, and has anti-Staphylococcus aureus effect, but the anti-inflammatory effect is unstable. Anti-inflammatory experiments showed that when 300 mg / Kg of xylene-induced auricle swelling was applied to the mouse auricle swelling model, it could significantly reduce xylene-induced mouse auricle swelling (P<0.01); Toluene induced ear swelling in mice (P<0.05). The analgesic experiment showe...

Abstract

The invention discloses a method for extracting new medicines which have the functions of anti-inflammation, detumescence, hemostasis, and the like, from a Chinese medicinal herb, yellow sweet clover. In the method, methanol, ethanol, acetic ether, aether, acetone and n-butyl alcohol are adopted as solvent and sweet clover extractum is prepared by heating and reflux extract, Soxhlet extract, ultrasonic extract or supercritical extract; quality analysis of flavone, polyphenol and coumestans in the extractum is carried out. The technological proposal which is suitable for developing new functional medicines is made according to the screening results of the pharmacodynamic tests of the functions of hemostasis, analgesia, bacteriostasis, anti-inflammation and detumescence.

Description

technical field [0001] The invention relates to the research of a Chinese herbal medicine and its drug development technology, in particular to the preparation method of its extract and the development of its drug preparation. Background technique [0002] Melissa officinalis is rich in coumarin compounds, which have various medicinal activities such as antibacterial, anticancer, anticoagulant, antiultraviolet, antihypertensive, swelling and pain relief. Chinese herbal medicine and marine organisms also have coumarins that inhibit HIV activity. Coumarin is a general term for a class of structurally similar substances, which have the advantages of small molecular weight and high bioavailability; although leguminous, orchidaceae, solanaceae, compositae and garciniaceae plants all contain coumarin, but various There are differences in the coumarin components of plant extracts. Therefore, different kinds of plant extracts may have different medicinal effects. [0003] Fan Jun...
