The invention relates to the technical field of tannic acid extraction, in particular to a method for extracting tannic acid by utilizing herba dendrobii. The method for extracting the tannic acid comprises the following steps: selecting any one or more of dendrobium huoshanense, dendrobium candidum, dendrobium moniliforme, dendrobium loddigesii rolfe, dendrobium fimbriatum, dendrobium chrysanthumand noble dendrobium as raw materials, and carrying out separation and purification technologies such as lixiviating, concentrating, atmospheric distillation, heating and distillation, filtering andresin purification, so as to effectively extract out the tannic acid with fine texture and pure white color, wherein the purity of a finished product tannin is 94.7 percent and the extraction rate is92.3 percent, so that the utilization rate and the use value of the herba dendrobii are effectively improved; the extracted finished product tannic acid has obvious and strong effects in the fields offoods, chemical engineering, cosmetics, medicines and the like; the medical effects of tannin with the same amount is 3 to 7 percent greater than that of the tannin extracted by utilizing the fructusschisandrae.

The invention discloses a method for directly planting dendrobium fimbriatum tissue culture seedlings in a field. According to the method, culture media are optimized, and after seedlings are obtained by using the optimized culture media through tissue culture, the seedlings are planted in the specific environment and by adopting a unique matrix. By adopting the method, the dendrobium fimbriatum tissue culture seedlings are directly planted in the field, and acclimation is needless, as a result, the culturing cost of the seedlings is reduced, and transplantation survival rate and seedling obtaining rate of the seedlings are remarkably improved.

The invention discloses a quality detection method of Dendrobium fimbriatum Hook. The quality detection method comprises: 1) sequencing by using ITS-26SE and ITS-17SE as primers to identify the variety of a to-be-detected Dendrobium herb; 2) carrying out chromatographic detection on n samples to obtain detection data using a chemical small molecule component schaftoside and / or naringenin as a reference component; 3) respectively carrying out fingerprint detection on the samples to obtain the fingerprint peak area value of the full chemical components of Dendrobium fimbriatum Hook; and 4) establishing an analysis model by using the content value of the schaftoside and / or naringenin in the chromatographic data as the response variable and using the peak area value of other components in thefingerprint as the independent variable, screening the variable through a Lasso method, and establishing the characteristic fingerprint model related to the chemical small molecule component. According to the present invention, through the first-generation sequencing and the characteristic fingerprinting, the quality of Dendrobium fimbriatum Hook is precisely identified and controlled.

The invention discloses a method for cultivating dendrobium fimbriatum. The method comprises the following steps of: after an axillary bud of a dendrobium fimbriatum pseudobulb grows into a high-bud seedling, cutting the high-bud seedling and transplanting onto a seedling adaptation substrate; and transplanting to the field for cultivating. In the cultivating method, the high-bud seedling grown by the dendrobium fimbriatum pseudobulb on a dendrobium fimbriatum stock plant is cut, so that each high-bud seedling does not damage the stock plant, the accelerated formation of a new high-bud seedling on the stock plant is stimulated, the reproduction speed and efficiency of a dendrobium fimbriatum germchit are increased, the reproduction quantity of the dendrobium fimbriatum germchit is increased, the reproduction period is shortened, and the dendrobium fimbriatum stock plant is brought into full play; moreover, the high-bud seedlings are transplanted to the field after seedling adaptation,so that the survival rate of the seedlings is up to about 98 percent and the germchits are ordered and consistent; and the method has the advantages of low cost, high survival rate and the like, and is suitable for scale culture and cultivation of seedlings.

The invention provides instant dendrobe powder as well as a preparation method and an application thereof. The preparation method of the instant dendrobe powder adopts wet granulation twice and concretely comprises the following steps: mixing fresh dendrobe with water, pulping and homogenizing to obtain slurry; adding auxiliary materials into the slurry, and carrying out spray draying to obtain dendrobe powder; mixing the dendrobe powder with ethyl alcohol, preparing a soft material and then carrying out granulation to obtain dendrobe granules; and drying the dendrobe granules to obtain the instant dendrobe powder, wherein the dendrobe comprises dendrobium officinale, dendrobium fimbriatum, nobile dendrobium, dendrobium thysiflorum, dendrobium devonianum paxt and the like. The preparation method of the instant dendrobe powder is simple, the obtained instant dendrobe powder is high in content of active ingredients, can be easily dissolved and can be widely applied to the field of medicines or health foods, so that the instant dendrobe powder has a good market prospect.

The invention discloses a fluorescent PCR detection kit for identifying three kinds of medicinal dendrobium in the Pharmacopoeia and its application. The detection kit includes specific primers and specific probes for Dendrobium nobile, Dendrobium tympani and Dendrobium fringe, as well as general primers and general probes for the genus Dendrobium, the sequences of which are shown in SEQ No.1‑12. The invention pairs specific fluorescent probes with templates, which has high specificity and specificity, high amplification efficiency, high sensitivity, high accuracy, good reproducibility, short detection cycle, and can be completed within 1.5 hours detection, and can detect DNA amplification reaction in real time, providing a strong guarantee for the quality and authenticity of the three kinds of medicinal Dendrobium recorded in the 2015 Pharmacopoeia.

The invention discloses a dendrobium tea and a making method thereof. The dendrobium tea is made by adopting fresh stems of Dendrobium fimbriatum Hook.var.oculatum Hook. and Dendrobium nobile, and a ratio of the Dendrobium fimbriatum Hook.var.oculatum Hook. to the Dendrobium nobile is 7-9:1-3. The dendrobium tea has the efficacy of resisting inflammations, resisting fatigue, resisting angiosclerosis, resisting tumors, resisting cataracts, resisting ageing, improving immunity and reducing blood sugar. A wine stir-frying technology used in traditional Chinese medicinal material processing is used in the making method of the dendrobium tea, so the leaching rate of effective components is improved, the dendrobium fragrance is lasting, and the technical problems of enough water and long-time decoction of dendrobium are successfully solved. The dendrobium tea produced through the method benefits human body absorption and utilization, has mellow taste, long sweet aftertaste, bright yellow color and lasting dendrobium fragrance, has stewing resistance, so the dendrobium tea produced in the invention has unique flavor and good quality.
