Embodiment 1

[0024] A phytoallelopathy inhibitor for the control of Artemisia gansuensis, including the epoxides of orangerene.

[0025] The orangerene epoxide is prepared by the following method, comprising the following steps:

[0026] (1) Obtaining the organic solvent extraction solution of allelochemical substances: Wash and crush the Artemisia arvensis donor material into 1-4mm, weigh 20g quantitatively, soak in 200ml of petroleum ether and ethyl acetate for 48 hours, every 12 hours Shake for 15 minutes, filter to obtain an organic solvent extract, and store at 4°C for future use. Obtain the extract for later use.

[0027] (2) Selection and packing of chromatographic column: adopt conventional method and dry column packing. Apply pressure to the bottom of the silica gel column to increase the flow rate of the eluent until the eluent flows out.

[0028] (3) Separation by column chromatography: mix the sample with silica gel, put 15ml of the solution to be tested into a round bottom ...

Embodiment 2

[0030] A phytoallelopathy inhibitor for the control of Artemisia gansuensis, including isoarrenene epoxides.

[0031] Isoarrenene epoxides are prepared by the following method, comprising the following steps:

[0032] (1) Obtaining the organic solvent extract of allelochemical substances: Wash and crush the Artemisia annua donor material into 1-4mm, weigh 20g quantitatively, soak in 200ml of petroleum ether and ethyl acetate for 48 hours, every 12 hours Shake for 15 minutes, filter to obtain an organic solvent extract, and store at 4°C for future use. Obtain the extract for later use.

[0033] (2) Selection and packing of chromatographic column: adopt conventional method and dry column packing. Apply pressure to the bottom of the silica gel column to increase the flow rate of the eluent until the eluent flows out.

[0034] (3) Separation by column chromatography: mix the sample with silica gel, put 15ml of the solution to be tested into a round bottom flask, add a small amo...

Embodiment 3

[0036] A plant allelopathic inhibitor for the control of Artemisia gansuensis, including 6-(2-(3-hydroxy-1-propenyl)yl)-4,8a-dimethyl-1,2,4a,5,6,7, 8,8a-Octahydro-2-naphthol.

[0037] 6-(2-(3-Hydroxy-1-propenyl)yl)-4,8a-dimethyl-1,2,4a,5,6,7,8,8a-octahydro-2-naphthol by following Method preparation comprises the following steps:

[0038] (1) Obtaining the organic solvent extraction solution of allelochemical substances: wash and grind Artemisia annua donor material into 1-4mm, weigh 20g quantitatively, soak in 200ml of petroleum ether and ethyl acetate for 48 hours, every 12 Shake for 15 minutes, filter to obtain an organic solvent extract, and store at 4°C for later use. Obtain the extract for later use.

[0039] (2) Selection and packing of chromatographic column: adopt conventional method and dry column packing. Apply pressure to the bottom of the silica gel column to increase the flow rate of the eluent until the eluent flows out.

[0040] (3) Separation by column chrom...

Abstract

The invention discloses a plant allelopathy inhibitor for controlling Gansu pedicularis. The inhibitor comprises orange alkene epoxide. On the basis of wild investigation, artemisia nanschanica capable of effectively inhibiting Gansu pedicularis is found. By extracting plant secondary metabolites of the artemisia nanschanica, three effective allelopathy inhibitors are found through biological tests, and the plant allelopathy inhibitor for controlling the Gansu pedicularis is invented through effective combinations. Material and technology support is provided for further industrially developing environment-friendly allelopathy inhibitors for effectively controlling the Gansu pedicularis on a large scale.

Description

technical field [0001] The invention relates to a plant allelopathic inhibitor for controlling Artemisia gansuensis, belonging to the field of chemical pharmacy. Background technique [0002] The control and elimination of poisonous weeds is an important work in agriculture, animal husbandry, gardening and other aspects. In effective agricultural and animal husbandry management, poisonous weeds have always been an important factor affecting production to a certain extent. From the developed chemical control to biological and ecological control, technical approaches have always been important tasks in the field of plant protection. However, effective and environmentally friendly control of poisonous weeds has not been well developed. Under the development trend of the concept of environment-friendly poisonous weed control, researchers have gradually turned to obtain materials and technical approaches for poisonous weed control from the natural field. Therefore, plant sourc...
