Process for microwave-freeze-drying dendrobium stem decoction medicine pieces

A process for microwave-freeze-drying dendrobium stem decoction medicine pieces comprises the steps of grading, wherein fresh dendrobium stems are divided into three grades according to the number of stem sections; cleaning, wherein the graded dendrobium stems are cleaned separately and drained off to be reserved; preprocessing, wherein the dendrobium stems which are drained off are placed into a microwave dryer and subjected to microwave processing for 1-3+/-0.5 minutes; segmented cutting, wherein each cooled dendrobium stem is divided into three segments according to the top, the middle portion and the root portion, and the top and the middle portion of each dendrobium stem are cut into thin sheets with the thickness from one mm to four mm; pre-freezing, wherein the cut dendrobium stem thin sheets are placed into a freezer and pre-frozen at the temperature from minus 10 DEG C to minus 20 DEG C for more than four hours; freeze-drying, wherein the cold trap temperature of a freezer dryer is lowered to be within the range of minus 55 DEG C to minus 65 DEG C for four to six hours, the pre-frozen dendrobium stem thin sheets are placed in the freezer dryer, and after sublimation is over and the temperature of a material disk returns to 20 DEG C, materials can be taken off after the temperature is kept at 20 DEG C for two to three hours, and then the dendrobium stem decoction medicine pieces are obtained.

Method for preparing donkey-hide gelatin oligopeptide

The invention provides a method for preparing donkey hide gelatin oligo-peptide and relates to a process for extracting pharmacodynamic substance from traditional Chinese medicine. The protein in the medicine normally can be absorbed and utilized by an organism only after being decomposed into the oligo-peptide or amino acid by the digestive juice enzyme. The collagen protein, which accounts for 80% of the content of the donkey hide gelatin, is difficult to be digested and absorbed, so that the due drug effect can not be produced. The method adopts the bionic principle and technology, i.e. extracting the pharmacodynamic substance of the oligo-peptide from the donkey hide gelatin by using the biological enzymolysis technology and the ultrafiltration technology. First, pepsin and trypsinase are added to the raw medicine of the donkey hide gelatin for hydrolyzation at a certain pH value and a certain temperature; then, ultrafiltration is conducted by using a 3kD or 5kD ultrafiltration column to obtain an ultrafiltrate, which is then separated and purified by using a macroporous resin column to further obtain a donkey hide gelatin oligo-peptide eluate; finally, the obtained donkey hide gelatin oligo-peptide eluate is decompressed, concentrated at a low temperature and dried to become the finished product of donkey hide gelatin oligo-peptide, which is verified by the pharmacodynamic test, has the efficacies of increasing the blood, enhancing the immunity of the organism, anti-aging, etc., and meanwhile provides the process and raw material for preparing other oral liquids and injections.
