Embodiment 1

[0027] The method for adding and extracting white jelly medium comprises the following steps:

[0028] Step 1: After washing 1000g of fresh bletilla root tubers with soil, wash them with 70% alcohol solution for 3-5 minutes, and then dry bletilla root tubers in the air;

[0029] Step 2: Cut the dried baiji root into flakes with a wheel squeezer, collect the juice produced by cutting the baiji root with the wheel squeezer to obtain the baiji juice, then put the baiji slices into clean water, Stir then, form white and fiber and white and water soaking liquid; Said wheel extruding cutter comprises cutter body 1, and the lower end of cutter body 1 is provided with the cutting edge 2 that twists and turns back and forth, and the side of cutter body 1 is provided with extruding roller 3, A spring 4 is arranged between the extrusion roller 3 and the cutter body 1, and the cutting edge 2 is perpendicular to the root of the root, and the root of the root is cut into sheets;

Embodiment 2

[0033] Compared with Example 1, the only difference is that in step 4, extracting Baiji gum by sublimation under reduced pressure, the specific operation method is to place the Baiji water soaking solution, Baiji water extract and Baiji juice into a closed extraction box for decompression sublimation extraction for 30d; a condensation pipe is provided above the inside of the extraction box, and the extraction box is communicated with a vacuum pump.

Embodiment 3

[0035] Compared with Example 1, the only difference is that in step 3, the river sand with a diameter of 5mm is washed with clean water, and then steam sterilized at 120°C, and then the river sand, white and fiber are put into the In a gauze bag.

Abstract

The invention belongs to the field of traditional Chinese medicine extraction, and concretely discloses a gum bletilla medium addition extraction method. The method comprises the following steps: 1, washing away soil on fresh bletilla rhizome root tuber, cleaning the washed bletilla rhizome root tuber with an alcohol solution with the concentration of 70% for 3-5 min, and airing the bletilla rhizome root tuber; 2, cutting the aired bletilla rhizome root tuber by using a roller squeezing knife to form sheets; 3, taking out bletilla rhizome fibers, cleaning a medium with clear water, sterilizing the cleaned medium with 120 DEG C steam, placing the medium and the bletilla rhizome fibers in an extractor, and extracting; and 4, mixing a bletilla rhizome water soak solution and a bletilla rhizome water extract liquid, and carrying out reduced pressure extraction. The gum bletilla medium addition extraction method is provided to solve the technical problem of low extraction rate of a water extraction and alcohol precipitation technology of glue bletilla in the prior art.

Description

technical field [0001] The invention relates to the field of extraction of traditional Chinese medicines, in particular to a method for adding and extracting bletilla jelly medium. Background technique [0002] Bletilla striata is the dry tuber of Bletilla striata. Bletilla striata gum, also known as Bletilla striata polysaccharide and Bletilla striata mannan, is a heteropolysaccharide obtained from Bletilla striata tuber after water extraction and alcohol precipitation. The extracted bletilla striata jelly has a wide range of pharmacological effects such as astringent and hemostasis, detumescence and muscle growth. It is very popular in clinic because it is easily absorbed by tissues and has low toxicity. [0003] There have been many reports on the extraction methods of bletilla striata gum at home and abroad. The method of water extraction and alcohol precipitation is widely used now, that is, placing the tubers of Baiji in water to obtain a water extract of Baiji, and t...
