Description
Technical field
The invention provides a kind of preparation method of ganoderma polysaccharide of high yield.
Background technology
Glossy ganoderma is the general name of red sesame of Basidiomycetes polyporaceae (Polyporaceae) Ganoderma (Ganoderma) fungi (G.lucidum) and purple sesame (G.japonicum), claim " Ganoderma lucidum seu Japonicum ", " celestial grass ", " auspicious grass " again, beginning is stated from " Shennong Bencaojing ", has strong, the effect such as strengthen the body resistance to consolidate the constitution, promote longevity of invigorating the spleen and replenishing QI, enriching yin.Ganoderan is one of main functional component of glossy ganoderma, and pharmacological testing shows that ganoderan has multiple pharmacological effect, as antitumor, hypoglycemic, immunomodulatory, anti-oxidant, antiviral etc.The hot water extraction is to extract ganoderan method commonly used.But there is long, problem such as temperature is high, yield is low of extraction time in the traditional hot water extract method, for overcoming the deficiency of traditional hot water extraction method, in recent years, has occurred ultrasonic or new extractive technique and method such as microwave-assisted extraction, ultra-high voltage, enzyme process.
Jin Danhong etc. have compared the influence to the ganoderan yield of Soxhlet, ultrasonic wave, three kinds of extracting method of microwave, and the result shows that microwave extraction method polysaccharide yield is the highest, be 0.868%.(Different Extraction Method is to the influence of ganoderan extraction yield, Chinese pharmacist, 2008,11 (5): 551-552).Du Bing etc. have carried out the technical study of ultra-high voltage extraction Ganoderma spore powder polysaccharide, polysaccharide yield is 2.763% under optimum extraction conditions, and conventional water extraction method polysaccharide yield only is the 2.014% (technical study of ultra-high voltage extraction Ganoderma spore powder polysaccharide, modern food science and technology, 2009,25 (5): 420-422,430).Wu Yingming etc. studies show that ultrasonication method and very low temperature freeze-thaw method have practical value in conjunction with extracting the Ganoderma spore powder polysaccharide, its yield can reach the 1.786% (influence that ultrasonic wave-very low temperature freeze thawing treatment is extracted the Ganoderma spore powder polysaccharide, edible fungi of china, 2008,27 (3): 34-35).Zhou Ming etc. adopt extracting Ganoderma lucidum polysaccharide by ultrasonic wave-microwave combination, and its yield can reach 1.49%, and (ultrasonic-microwave synergistic extraction is to the influence of ganoderan extraction yield, hubei agricultural science, 2009,48 (7): 1727-1729.).Inventions " enzymolysis prepares the method for ganoderan " (200410019093.9) such as China National Academy of Food ﹠ Fermentation Industries Cai Yong peak, the mixed enzyme of utilizing mycelium self enzyme system and adding ties up under the suitable condition carries out enzymolysis to the Ganoderma fermented liquid, behind the enzymolysis in the ganoderma lucidum crude polysaccharide product ganoderma polyoses content be 35-60%.Tianjin Forestry and Fruit Tree Inst.'s Zhang Zhijun etc. inventions " preparation method of ganoderma polysaccharide " (200510014592.3), the main ganoderan product that Ganoderma sporophore is obtained through method such as pre-treatment, micro-filtration, subzero fractionation, membrane sepn, membrane concentration, concentrating under reduced pressure, drying under reduced pressure that adopts.The Hu Qiuhui of Agricultural University Of Nanjing etc. invent " a kind of high efficiency preparation method of ganoderan " (200810156039.7), adopt ultrasonic wave extraction, polysaccharide yield is 20.79 ± 0.11mg/g, purity has reached 47.88%, compare with traditional hot water lixiviate, time has shortened 96%, and yield has improved 28%.Hubei Province Academy of Agricultural Sciences, the processing of agricultural products and Nuclear Agricultural Research Institute Zhou Ming etc. invent " a kind of method of ultrasonic wave microwave synergistic extraction ganoderan " (200810048683.2), has the bonding force that alternative extraction solvent kind is many, the target extract is in extensive range, reduce target compound and sample matrices, quicken the process that target compound enters solvent phase from solid phase, and characteristics such as quantity of sample handling is big.Wu Mei etc. have carried out the research that alkali is carried the caustic solubility lucidum mycelium polysaccharide, wherein adopt 0.5mol/L NaOH dissolving alcohol to analyse, and sugared yield is that 1.3% (alkali is carried the research of caustic solubility lucidum mycelium polysaccharide method, Yunnan University's journal, 1999,21 (2): 160-161).
From present result of study as can be seen, carry out the extraction of water-soluble ganoderan merely, its extraction yield has only about 3%, also contain other polysaccharide of part in the glossy ganoderma residue after the extraction, as the caustic solubility protein-polysaccharide, glycosaminoglycan is if directly abandon, both caused the wasting of resources, again environment had been polluted.Carry out the extraction of caustic solubility ganoderan merely, owing to there be not the recovery of consideration to water-soluble ganoderan, its extraction yield is also very limited.
