Problems solved by technology

Although the agarwood produced by this method meets the national requirements for the content of its alcohol-soluble extracts, the composition of the agarwood flavor enhancer does not consider how to increase the content of agarwood oil and the content of sesquiterpene in the agarwood oil

Embodiment 1

[0021] Example 1: Production of agarwood by infusion method and test comparison

[0022] 1. The inventive method

[0023] Choose a 5-year-old tree with a DBH greater than 10 cm. At a distance of 5 cm from the ground, use an ordinary electric drill for the vertical trunk with a drill bit diameter of 0.6 cm to drill two holes with a depth of 5 cm. Prepare 500ml of 0.1% methyl jasmonate, 0.5% NaCl and 0.3% phenylethanol solution, slowly input it into the drill hole, and seal the hole with a rubber stopper to prevent the outflow of the agarwood agent and the erosion of rainwater. After 3 days, part of the leaves of the Arakita japonica tree fell off. Add it dropwise once every 1 month. After 3 months, cut off the tan oily substance formed around the wound and the yellow-brown discolored xylem, and dry it to obtain agarwood.

[0024] 2. Comparison method

[0025] No phenylethanol solution is added to the incense-forming liquid, and the rest of the incense-forming conditions are ...

Embodiment 2

[0031] Example 2: Production of agarwood by infusion method and test comparison

[0032] 1. The inventive method

[0033] Choose an agarwood tree that is 8 years old and has a diameter at breast height of 8 cm or more. At a distance of 2 cm from the ground, use an ordinary electric drill with a drill bit diameter of 0.6 cm to drill two holes 4 cm deep at a distance of 2 cm from the ground. Preparation containing 0.01% 6-BA, 0.1% MgCl 2 and 0.2% phenylethanol solution 500ml, slowly input it into the drill hole, and seal the hole with a rubber stopper after the input to prevent the agarwood from flowing out and rainwater. After 4 days, part of the leaves of the Arborina japonica tree fell off. Add it dropwise once every 2 months. After 12 months, cut the tan oily matter and yellow-brown discolored xylem formed around the wound, and dry it to obtain agarwood.

Embodiment 3

[0041] Example 3: Production of agarwood by infusion method and test comparison

[0042] 1. The inventive method

[0043] Choose an agarwood tree that is 10 years old and has a DBH greater than or equal to 15cm. At a distance of 10cm from the ground, use an ordinary electric drill with a drill bit diameter of 0.6cm to drill two holes with a depth of 7.5cm at a distance of 10cm from the ground. Preparation containing 0.01% 6-BA, 0.05% ethephon, 0.05% MgCl 2 and 500ml of phenylethanol solution of 0.5%, slowly input it into the drilling hole, and seal the hole with a rubber stopper after the input to prevent the agarwood medicine from flowing out and rainwater washing away. After 4 days, part of the leaves of the Arborina japonica tree fell off. Add it dropwise once every 2 months. After 24 months, cut the tan oily matter and yellow-brown discolored xylem formed around the wound, and dry it to obtain agarwood.

Abstract

The invention relates to the field of biotechnology and discloses an agilawood production method. The method comprises the steps of first drilling a hole in a trunk of aquilaria malaccensis or aquilaria sinensis, enabling an agilawood inducer formed by plant hormones, inorganic salt and phenethyl alcohol to be added dropwise into the tree in a transfusion mode, then sealing the hole, adding the agilawood inducer dropwise at an interval of 1-2 months, performing treatment for 3-24 months in total, then cutting brown oily matter and yellowish-brown discolored xylem in the trunk, and obtaining agilawood after drying in the sun. The plant hormones are one or more than two of methyl jasmonate, ethephon and 6-BA; and the inorganic salt is one or both of sodium chloride and magnesium chloride. Components of the agilawood inducer are adjusted on the basis of an existing agilawood inducer, a trunk defense system is excited, related enzymes for synthesizing agilawood chemical components are generated and act on phenethyl alcohol, the trunk generates related chemical components in the agilawood, and finally the agilawood is formed by accumulation. According to the method, not only are contents of agilawood oil and sesquiterpenes in the agilawood oil improved, but also contents of alcohol-soluble extracts are improved.

Description

technical field [0001] The invention relates to the technical field of biological preparation, in particular to a method for producing agarwood. Background technique [0002] Agarwood is the xylem of Aquilaria agallocha Roxb. or Aquilaria sinensis (Lour.) Gilg.] containing black resin. The former is mainly produced in India, Malaysia and other places, and our country calls it imported agarwood, while the latter is mainly produced in Hainan, Guangdong, Guangxi and other provinces and regions in my country, and is called domestic agarwood or soil agarwood. Agarwood is not only a traditional precious medicinal material in my country, Japan, India and other Southeast Asian countries, but also a precious natural spice. Agarwood has a history of at least 3,000 years in the Middle East, China, and Japan. It is also recorded in India and France, and even in the Old Testament of the Bible. At present, agarwood is still one of the most expensive spices in the world, and the value of...
