The dosage of compound biological enzyme: with the flower of land plant, leaf, dosage was the 0.1%-0.5% of substrate quality when fruit was substrate.With the root of land plant, dosage was the 0.3%-0.8% of substrate when stem was substrate; Dosage is the 0.8%-3% of substrate when being substrate with the marine plant.
The invention foundation
Cellulase has decomposition, softening fibre element, destruction cell walls, increases the effect of the stripping quantity of vegetable cell content, it is the general name of the glucogenic one group of enzyme of degraded cellulose, comprises endoglucanase, cellobiohydrolase, 3 components of beta-glucosidase.Optimum pH 4～5,40 ℃～60 ℃ of the best use of temperature.
Hemicellulase is by endo-type enzymes such as 'beta '-mannase, beta-xylanases, circumscribed-type enzyme and compositions such as arabinofuranosidase/xylosidase, tilactase, glucuronidase and acetyl zytase such as beta-glucosidase, beta-Mannosidase, xylobiase.Effect with digestion plant cell wall.
Polygalacturonase is the general name of a class prozyme of glycan lytic enzyme, the pectin substance Acyl-hydrolase of decompose pectin matter.45 ℃-50 ℃ of optimum temperatures, action pH value 3～6.
Amylase is the enzyme general name of hydrolyzed starch and glycogen, is divided into α-Dian Fenmei and beta-amylase usually.
Proteolytic enzyme plays the group attribute of katalysis according to the active centre of enzyme, can be divided into serine/threonine protein enzyme, thiol proteinase, metalloprotease and aspartate protease etc.Proteolytic enzyme can resolve into peptide with protein, is hydrolyzed into amino acid through peptase again.
The advantage that compound biological enzyme of the present invention is used for the effective ingredients in plant extraction has:
1, utilize enzyme reaction to have highly narrow spectrum characteristics, select different enzymes to be mixed in proportion, moiety (as Mierocrystalline cellulose, hemicellulose, pectin substance etc.) hydrolysis or degraded with plant cell wall, destroy cell wall structure, make the fully dissolving of intracellular composition, suspendible or peptization in solvent, thereby reach the extraction purpose, improve extraction efficiency, reduce production costs.Utilize the present invention can make extraction yield increase more than 15%.
2, plant combinative enzyme hydrolysis mild condition has reduced the difficulty of solvent extraction subsequently, makes whole extraction process mild conditionization, helps to keep original character of effective component.
3, can destroy plant cell wall at low temperatures quickly and effectively, the extract at low temperature of pharmaceutically active ingredient in helping to realize, the destruction of reducing effective constituent is reduced energy consumption.
