Description
Technical field:
The present invention relates to the nucleoside active matter in the artificial culture Cordyceps militaris (L.) Link. (Cordyceps militaris (L.) Link), and its production and use.
Background technology:
Cordyceps militaris (L.) Link. [Cordyceps militaris (L.) Link], another name Cordyceps militaris (L.) Link., Cordyceps militaris, belong to Mycophyta (Eumycota) Ascomycotina (Ascomycotina) gang pyrenomycetes (Pyrenomycetes) Spheeriales (Sphaeriales) Clavicipitaceae (Clavicipitaceae) Cordyceps (Cordyceps), Chinese scholars thinks that the imperfect stage of Cordyceps militaris (L.) Link. is cephalo bacterium (Cephalosporium) or Paecilomyces varioti (Paecilomyces).Cordyceps militaris (L.) Link. is a cosmopolitan species, mainly is distributed in states such as China, the U.S., Japan, USSR (Union of Soviet Socialist Republics), West Germany, Canada, Italy.China mainly is grown in provinces and regions such as Jilin, Liaoning, Hebei, Shaanxi, Guangxi, Guangdong, Yunnan, Sichuan, Guizhou, Hubei, Hunan.
Cordyceps sinensis generally is grown in the above extremely frigid zones of height above sea level 3800 granular snow lines, and the sea level elevation of growing environment, weather condition etc. are had special requirement, natural resources scarcity.The biological study of Cordyceps sinensis shows, all there are the digenesis phenomenon in Cordyceps sinensis and parasitic pupa thereof, and can be single for the kind of the parasitic pupa of battalion, also very strict to the growth cycle requirement of parasitic pupa, so brought difficulty for its growth conditions of manual simulation.The researchist was once reaching inoculation culture on some polypide on the multiple substratum, except that on different substratum and the polypide that has, forming the bar-shaped coremium, do not observe at present the stroma (Song Zhenyu of perithecium and thecasporous perfect stage as yet, the herbal medicine modern study, combined publication society of China Concord Medical Science University of Beijing Medical University, 1995.100-110).
Because the artificial culture of Cordyceps sinensis can not obtain stroma, Chinese scholars focuses onto the liquid submerged fermentation that the fermentation engineering of seeking surrogate aspect and Applied Biotechnology has been carried out Cordyceps sinensis, succeeded in developing some fermented hypha products in succession and thrown in the medical market, for example paecilomyces hepiall chen, peaceful heart health-care capsule, zhiling capsules etc.
Cordyceps militaris (L.) Link. is grown in secondary forest belt more, ground surface environment is with in softwood forest, broad-leaf forest or the mixed forest, environment requirement does not have the Cordyceps sinensis strictness, the sea level elevation of growth is generally between 150-500 rice, live in the soil or the bark on leaf, thick grass and face of land seam in, its host mostly be the pupa of lepidopterous insects or larva (Xu Jintang, Chinese medicinal fungi is learned, the People's Health Publisher, 1995.354-395).At present, have report to show: the artificial culture of Cordyceps militaris (L.) Link. can grow stroma at solid medium with the bacterial classification inoculation that separates, purifying obtains from natural Cordyceps militaris (L.) Link., with the natural identical (Ran Cuixiang of Cordyceps militaris (L.) Link. stroma CF, cultivate the formation of bringing out of Cordyccps-militaris-(L.)-link. Sporophore, edible mushrooms, 2001.23 (4) 9-10).Liquid culture to Cordyceps militaris (L.) Link. can reach the imperfect stage, forms mycelium, and its zymotechnique has been carried out preliminary exploration (male, the Sun Shuyuan of Wang Qing, the progress of the medicinal Cordyceps mycelium of China's liquid culture, edible mushrooms, 1997.16 (3): 2-4).
Chemical ingredients is numerous in the Cordyceps sinensis fungus, comprises nucleoside compound, Cordyceps polysaccharide, sterols, amino acid, peptide class, organic acid, VITAMIN and trace element etc.Wherein nucleoside compound comprises cordycepin, adenosine, guanosine, uridine, VITAMIN B4, uridylic, xanthoglobulin, inosine etc.
Cunningham and Frederiksen (Cunningham K G etc., J Chem Soc, 1951,2299-2307; Frederiksen, Matting etc., Biochem Bio Acta, 1965,95:189-193) having equaled the reported first fifties isolates ucleosides antibiotic-cordycepin and finds its significant anti-cancer activity from the nutrient solution of Cordyceps militaris (L.) Link., caused the extensive attention of people to nucleoside compound in the Cordyceps sinensis fungus, new nucleosides material constantly is found.Xu great writer (Xu great writer etc., the research of the water soluble component-nucleoside compound of Cordyceps sinensis, bulletin of Chinese materia medica, 226~228) etc. 1988,13 (4): utilize strong-acid ion exchange resin, macroporous adsorbent resin and silica gel column chromatography from the stroma of Cordyceps sinensis is produced in Tibet, to get inosine, thymus pyrimidine, uridylic and the assorted xanthoglobulin that guanine is arranged; From polypide, obtain micro-xanthoglobulin, guanine, VITAMIN B4 and adenosine.Liu Jingming (Liu Jingming etc., Cordyceps militaris (L.) Link. chemical constitution study, CHINA JOURNAL OF CHINESE MATERIA MEDICA, 1989,14 (10): 32-33) wait the Dowex-I[chlorine type that utilizes] resin column separates from the Cordyceps militaris (L.) Link. mycelia and obtains VITAMIN B4, adenosine and cordycepin.Liu Ke (Jiang Hong etc.; artificial cordyceps militaris fruiting body's chemical ingredients; Acta Pharmaceutica Sinica 2000,35 (9): 663-668) wait methods such as utilizing silica gel column chromatography, preparation liquid phase, preparation thin layer from the ethanol extraction of the Cordyccps-militaris-(L.)-link. Sporophore of artificial culture, to separate and obtain cordycepin, adenosine, N6-methyladenosine, O5 '-ethanoyl cordycepin, N6-[β-(ethanamide formyl) oxygen ethyl] 5 nucleoside compounds such as adenosine.
The inventor's comparative study shows: though the domestic report of the Analysis of Nutritional of Cordyceps militaris (L.) Link. and Cordyceps sinensis is more, the content analysis of the multiple composition of Cordyceps militaris (L.) Link. ucleosides is not seen play-by-play.This study group measures through the HPCE method and finds, content of cordycepin can reach 5.04 times of natural Cordyceps militaris (L.) Link. stromas in the artificial culture Cordyceps militaris (L.) Link. stroma, and cordycepin, adenosine, guanosine content can reach 10.85,2.58,3.99 times of natural Cordyceps militaris (L.) Link. stroma respectively in the liquid culture Cordyceps militaris (L.) Link. fermented hypha.This shows that under the situation that natural cordyceps, Cordyceps militaris (L.) Link. resource constantly reduce, the mycelia that can utilize the Cordyceps militaris (L.) Link. stroma of artificial culture and liquid culture is product as an alternative.
In the Cordyceps mycelium of artificial culture and the stroma content majority of nucleoside compound approaching, have in addition surpassed natural cs.Especially content of cordycepin is apparently higher than natural cs in the Cordyceps militaris (L.) Link. mycelia of artificial culture and the stroma, and this is just for providing theoretical foundation the artificial culture Chinese caterpillar fungus as the surrogate of natural cs.
The seventies in 20th century, external scientist had once carried out big quantity research to the antitumour activity of cordycepin, but abandoned owing to its cytotoxicity is excessive.The principle that the present invention mainly " complements each other " according to each component/composition in the Chinese materia medica medication, be surprised to find that the nucleoside active matter in the artificial culture Cordyceps militaris (L.) Link. has in the good body and the effect of vitro inhibition tumour, cytotoxicity reduces simultaneously, and cost also reduces.
