| titleOfInvention | A kind of technique that enzymatic isolation method extracts Dendrobium officinale polysaccharide |
| abstract | The invention discloses the techniques that the enzymatic isolation method of a kind of efficient, safety, suitable industrialized production extracts Dendrobium officinale polysaccharide.It mainly comprises the steps that and takes dendrobium candidum, it crushed 20-80 mesh, 4-6 times of amount is added and contains pectase: cellulase: the weight ratio of laccase (1-2:1-3:0.5-2.5) is mixed and made into the glacial acetic acid buffer solution of compound enzyme system, and (ice acetic acid solution adjusts pH value to 4.0-6.0), 25-50 DEG C of controlled enzymatic hydrolysis temperature digests 1-5h.It is transferred in appropriate vessel, adds 4-8 times of drinking water, refluxing extraction 2h, filter (120 mesh), filtrate is concentrated into relative density 1.25-1.40 (60 DEG C)；Ethyl alcohol, which is added, makes medical fluid alcohol content up to 70-80%, stirs evenly, and after standing 12h, centrifugation collects sediment, flings to ethyl alcohol；60-80 DEG C vacuum drying to get.Polyoses content and mannose content are measured respectively and calculates recovery rate, and as a result Dendrobium officinale polysaccharide recovery rate is 39.88%-46.16%, and mannose recovery rate is 48.26%-55.63%. |
