Example Embodiment

[0026] Example 1

[0027] A preparation method of Dendrobium sylvestris powder includes the following steps:

[0028] (1) Cleaning treatment: remove the leaves of fresh dendrobium sclerophyllum, soak it in a cleaning solution for 6 minutes, then remove it and send it to a dehydrator to remove the water on its surface, and set aside:

[0029] (2) Drying: Send the dehydrated dendrobium to the hot air circulation oven, dry it at 50-60°C to a moisture content of 60-70%, and cut into Dendrobium slices;

[0030] (3) Freezing treatment: freeze the Dendrobium slices at -15°C for 20h;

[0031] (4) Differential pressure puffing treatment: adding frozen Dendrobium tablets into an expansion tank for differential pressure puffing to prepare expanded Dendrobium tablets;

[0032] (5) Low-temperature reflux extraction and concentration: add the extruded Dendrobium flakes to a hot reflux low-temperature extraction low-temperature concentration machine, add an organic solvent of 8 times its mass to low-te...

Abstract

The invention relates to a preparation method of dendrobium aurantiacum powder. The preparation method comprises the following steps of (1) performing cleaning treatment: removing leaves of fresh dendrobium aurantiacum, adding the dendrobium aurantiacum without leaves in cleaning liquid, performing soaking and cleaning, performing fishing out, and removing surface moisture for standby application;(2) performing drying: drying the dehydrated dendrobium aurantiacum until the water content is 60-70%, and performing cutting into slices; (3) performing freezing treatment: freezing the dendrobium aurantiacum slices; (4) performing differential pressure puffing treatment: performing differential pressure puffing on the frozen dendrobium aurantiacum slices, to prepare the puffed dendrobium aurantiacum slices; (5) performing low-temperature reflow extraction and concentration: adding an organic solvent to the puffed dendrobium aurantiacum slices, and performing low-temperature reflow extraction and concentration to prepare primary concentrate; (6) performing concentration: sending primary concentrate into a spherical vacuum concentrating tank, and performing concentration to prepare secondary concentrate; (7) performing drying and crushing: drying a secondary concentrated solution, and performing crushing, to prepare crude dendrobium aurantiacum powder; and (8) preparing components. According to the method provided by the invention, the bioactive components of the dendrobium aurantiacum are low in loss rate, high in dissolving and leaching efficiency and high in biology absorptionand utilization rate.

Description

technical field [0001] The invention belongs to the technical field of medicinal material extraction, and in particular relates to a preparation method of dendrobium sheathing dendrobium powder. Background technique [0002] Dendrobium dendrobii is a variety of Dendrobium lanceolata, which is mainly distributed in the southwest of Sichuan Province, the southwest to northwest of Guangxi, the south of Guizhou, and the southeast of Yunnan. At present, it is widely cultivated and used for medicinal purposes in Jiajiang County, Leshan City, Sichuan Province. The difference between Dendrobium sheathing and the original variety is that the plant is obviously thicker, the stem is more than 4 mm thick, the leaves are 1.8-4.5 cm wide, the inflorescences are 5-14 cm long, the bracts are 1.8-3 cm long, and there is a big purple on the lip. plaque. Dendrobium dendrobii mainly contains polysaccharides, tannins, bibenzyls, alkaloids, coumarins, sugars, glycosides, phenanthrenes, fluoreno...
