Embodiment 1

[0031] Embodiment 1: Preparation of dendrobium extract

[0032] Dendrobium extract of the present invention, obtain through following method:

[0033] a. Cut the dendrobium into pieces with scissors, add it into water and boil according to the W / V ratio of 1:10-20, keep the dendrobium in water for 2-4 hours after boiling, then filter and discard the residue with gauze, and collect the extract ;

[0034] b. Repeat step a for 2 to 4 times, combine the extracts each time, and obtain the powdered dendrobium extract after the extracts are subjected to conventional freeze-drying;

[0035] Described dendrobium refers to the wild or cultivated fresh dendrobium or dried dendrobium purchased in the market.

Embodiment 2

[0036] Embodiment 2: Preparation of dendrobium aqueous extract solution

[0037] The dendrobium aqueous extract prepared in Example 1 was mixed evenly with water to prepare dendrobium aqueous extract solutions with concentrations of 5 μg / ml, 10 μg / ml, 20 μg / ml, 50 μg / ml and 100 μg / ml respectively.

Embodiment 3

[0038] Embodiment 3: Preparation of dendrobium water extract ointment

[0039] The aqueous extract of Dendrobium prepared in Example 1 was uniformly mixed with petrolatum to prepare aqueous extract ointments of Dendrobium with concentrations of 0.02% (W / W), 0.2% (W / W) and 2% (W / W).

Abstract

The invention relates to a dendrobe extract and application of the dendrobe extract and belongs to the technical field of pharmacy. The dendrobe extract is obtained by the following method that a, dendrobe is cut into pieces by scissors and water is then added for boiling according to the proportion that the W / V(weight / volume) is 1:(10-20), the boiling is continuously maintained for 2 to 4 hours after the dendrobe is boiled in the water, the filtering is carried out, residual slag is removed, and extraction liquid is collected; b, the step a is repeated for 2 to 4 times, the extraction liquid in each time is combined, and powdery dendrobe water extracts are obtained through freeze drying; c, the dendrobe water extracts obtained in the step b are uniformly mixed with the water to be prepared into dendrobe water extract solution with the concentration being 5Mu g / ml-100Mu g / ml; and d, or the dendrobe water extracts obtained in the step b are uniformly mixed with vaseline to be prepared into dendrobe water extract paste with the W / W (weight / weight) concentration being 0.02 percent-2 percent. The dendrobe extract is applied to the preparation of medicine for promoting the skin scar tissue repair. The dendrobe extract and the application have the beneficial effects that the scar tissue formation can be obviously reduced by the dendrobe, the application prospect of preparation of the medicine for promoting the skin scar tissue repair is shown, and a new application field is developed for the dendrobe.

Description

Technical field: [0001] The invention relates to a dendrobium extract and its application, belonging to the technical field of pharmacy. Background technique: [0002] Trauma is an important disease that affects the health of the body. In my country, there are millions of people injured by trauma every year. Almost all the traumatized people have different degrees of skin trauma. All skin trauma involving the dermis will be caused by the formation of scar tissue. end. Excessive hyperplasia of scar tissue often destroys the integrity of the human body surface, which not only affects the appearance, but also seriously affects the normal function of the body, causing patients both mental and physical pain. For this reason, how to reduce the scar formation after trauma repair has always been the focus of research in the field of plastic surgery, and it is also a difficult problem for the entire medical field. Although a large number of research results have shown that many intr...
