Definitions
- the present invention relates to an extract of lactolithium having an activity of inhibiting NO generation and a preparation method thereof.
- BACKGROUND-Everyday inflammatory diseases that plague people include arthritis such as osteoarthritis, rheumatoid arthritis, rheumatoid spondylitis, gout arthritis, etc .; inflammatory skin diseases such as eczema, psoriasis, dermatitis, etc .; inflammatory Eye diseases such as uveitis, conjunctivitis, etc .; Pulmonary diseases such as asthma, bronchitis, acute respiratory distress syndrome, etc .; Bacteremia, natoxemia, aphthous ulcer, gingivitis, pancreatitis, etc .; Gastrointestinal diseases For example, segmental ileitis, atrophic gastritis, ulcerative colitis, peritonitis, peptic ulcer, stress bowel syndrome such as mucosal inflammation caused by Helicobacter p
- Nitric oxide (N O) in the body is known to be a toxic substance that mediates cellular immunity and inflammation. Its precursor is L-arginine (L-arg).
- L-arg L-arginine
- One of the two identical hydrogen atoms on the guanidino group at the end of L-arg generates NO under the action of NO synthetase (NOS).
- NOS NO synthetase
- Three different types of NOS have been isolated, including endothelial NO synthase (eNOS), neuronal NO synthase (nNOS) and inducible NO synthetase (iNOS).
- eNOS endothelial NO synthase
- nNOS neuronal NO synthase
- iNOS inducible NO synthetase
- iNOS inducible NO synthetase
- the Chinese Patent Publication No. is: CN1458155A "—A New Antitumor Compound, Lathyol B”
- the structural formula of a compound, bulbophylol B, is:
- the present invention extracts a component with clear anti-inflammatory activity from rhododendron, which is safe and non-toxic, and can effectively inhibit the generation of NO to achieve an anti-inflammatory effect. Disclosure of the Invention-The purpose of the present invention is to extract a component with clear anti-inflammatory activity from the medicinal plant Rhododendron, which can effectively inhibit the production of NO and achieve an anti-inflammatory effect.
- the present invention provides a rhododendron extract 1 having the following structural formula: Lithuania extract 1 has an activity to inhibit NO production.
- the present invention also provides a lactolithium extract 2, which has the following structural formula: Lithuania extract 2 has an activity of inhibiting NO production.
- the present invention also provides a rhododendron extract 3, which has the following structural formula : Lithuania extract 3 has an activity to inhibit NO production.
- the invention relates to a method for separating an active compound from a medicinal plant Bulbophgllum radiatum Lindl, which is characterized by comprising the following steps ⁇
- step 2) separating the ethyl acetate and petroleum ether eluate in step 2) by column chromatography;
- step 4) The eluate collected in step 3) was concentrated under reduced pressure, and further separated and purified; the compounds isolated in step 4) were analyzed for physicochemical properties to determine their structure; test.
- the concentration of the ethanol extract of the rhododendron is 60%;
- the chromatography column can be selected in a silica gel column or a Sephaden LH-20 column; and the eluent can be in chloroform: methanol (volume ratio of 100: 0, 95: 5, 90:10, 85:15, 80:20). , 70: 30, 60: 40, 50: 50, 0: 100), or n-hexane: ethyl acetate (100: 0, 95: 5, 90: 10, 85: 15, 80: 20, 70 by volume) : 30, 60: 40, 50: 50, 0: 100), or n-hexane: acetone (100: 0, 95: 5, 90: 10, 85: 15, 80: 20, 70: 30, 60) : 40, 50: 50, 0: 100).
- the concentration under reduced pressure is preferably performed at 40 ° C.

- a lactobacillus orchid extract 6 is characterized in that it has the following physical and chemical parameters:
- a lactobacillus orchid extract 7 characterized in that it has the following physical and chemical parameters:
- Compound 7 was isolated from rhododendron according to the method described above.
- the invention also relates to the application of the above-mentioned lactolith extracts 1, 2, and 3 in the preparation of a medicament for treating inflammation related to NO production.
- the beneficial technical effect obtained by the present invention is that for the first time, an extract with clear anti-inflammatory activity is isolated from rhododendron, and as a natural NO production inhibitor, it overcomes the toxic and side effects of chemical synthetic substances. Best Practice:
- the entire powder extract was dissolved in 2 liters of water, and extracted three times with 2 liters each of petroleum ether, ethyl acetate, and n-butanol, and the ethyl acetate extract in these extracts was concentrated under reduced pressure at 40 ° C. 32.6 g of brown powder were obtained.
- the petroleum ether eluent was concentrated to obtain 29.3 g of brown powder, and subjected to silica gel column (Qingdao Ocean Chemical Plant) chromatography.
- the 95: 5 eluate was concentrated under reduced pressure at 40 ° C.
- the inhibitory effect of megalith phages on NO production (inhibition of NO production) due to the stimulation of interferon r and lipopolysaccharide was obtained by the following experimental method.
- the inhibitory effect was evaluated based on the IC50 (um) of the inhibitory effect.
- N-1-naphthalene ethylenediamine hydrochloride (lg Wako Pure Medicine)
- Lipopolysaccharide (LPS, 055: B5 lOmg, Sigma)
- Cytotoxicity was determined by MTT and by microscopy.
- the MTT method is a known conventional method. Gen Jie, a 96-well microtiter plates, each well 200 ⁇ ⁇ a cell concentration of 1.0 105 cells / 111, different concentrations of an extract component or monomer, the cells were cultured for 16 hours, ⁇ reagent, Incubate for another 4 hours. The supernatant was discarded, and 150 LDMS0 was added to completely dissolve the generated formazane, and the absorbance at 570 nm was measured.
- N-1-naphthalene ethylenediamine hydrochloride N- 1 -Naphthyethylene-diamine Dihyrochloride
