[0029]1. Prepare 2% sodium hydroxide methanol solution, spray the sodium hydroxide methanol solution on the base of the leaves for 24 hours, rinse the alkali-treated parts with 10 times the amount of lye, and wait for 2-3 months. After growing long and forming Dracaena, continue to cultivate Dracaena for 2-3 months, cut off the lipid-containing leaves, remove the green part of the leaf that does not produce Dracaena, keep the red lipid-containing part, extract with 95% ethanol after drying, The extract is dried to obtain dried blood.

[0030] 2. Prepare 6% potassium hydroxide aqueous solution, and spray the potassium hydroxide solution directly on the young leaves of Dracaena in mist form. After 48 hours, rinse the alkali-treated leaves with 20 times the amount of water. Manage under normal growth conditions. After 3 months, harvest the fat-producing leaves, remove the green parts of the leaves, and keep the red fat-containing parts. After the fat-containing leaves are dried, ...

Abstract

The invention relates to a method for inducing the generation of dragon blood through the alkali treatment on live leaves of dragon trees. The method consists of the following steps: 1. an alkaline matter is compounded with liquid or solid powder; 2. the compounded alkaline matter is applied on leaves of a dragon tree or meristem generating the leaves; 3. after the leaves of the dragon tree are treated by the alkaline matter for a period of time, and the alkaline matter is removed by washing with water or other methods; 4. after the live leaves of the dragon tree are subjected to alkali treatment for a period of time, dragon blood can be formed; and 5. the fat-containing leaves generating the dragon blood are harvested, dried and extracted by use of ethanol or methanol, and the dragon blood can be obtained after an extract is dried. The method aims to solve the technical problems of utilizing the characteristic that the leaves of the dragon tree are high in renewal speed and the alkaline matter is taken as an inducer for inducing the leaf damage of the dragon tree and the formation of the dragon blood, so as to solve the problem of the sustainable utilization of dragon tree resources.

Description

[0001] Technical field: the present invention belongs to the field of biopharmaceuticals technical background [0002] Dragon’s blood (or Resina Draconis) is a traditional precious traditional Chinese medicine, which has the effects of promoting blood circulation and removing blood stasis, analgesic hemostasis, anti-inflammatory and antibacterial effects. It has a long history of use in my country, but it has always relied on imports. In the natural state, after the xylem of the trunk of Dracaena is damaged or infected by microorganisms, the plant will produce a defense reaction and form a defensive substance to resist microbial infection. In 1972, Chinese medical workers discovered Dracaena cochinchinensis (Lour.) S.C. Chen, which can produce dried blood, in Yunnan, Guangxi and other places. In the national standard (WS3-082(Z-016)-99(Z)) promulgated by the State Drug Administration in 1999, dried blood was recorded as a class of new medicinal materials. Wild dracaena resour...
