Embodiment 1

[0026] Experimental group: Dissolve a quantitative amount of cyclin compound in methanol with a solution concentration of 282.6 μg / mL, add 1 mL of the solution to a petri dish with a diameter of 6 cm, and make it evenly cover the bottom of the petri dish. After the solvent is completely evaporated, the content of the cyclin compound coated on the bottom of the petri dish is 10 μg / cm 2 . Add 13 mL of filter-sterilized seawater.

[0027] Control group: Add 1 mL of solvent methanol to make it evenly distributed on the bottom of the culture dish. After the solvent is completely evaporated, add 13 mL of filtered and sterilized seawater.

[0028] Blank group: Add 13 mL of filtered and sterilized seawater.

[0029] Four parallel samples were set up in each of the experimental group, the blank group and the control group. During the attachment test, the reticulated barnacle Venus larvae were randomly assigned to the blank group, the control group, and the experimental group. About ...

Embodiment 2

[0033] Experimental group: Dissolve the cyclin compound in methanol to prepare a solution with a concentration of 28.26 μg / mL. Add 1 mL of this solution to a petri dish with a diameter of 6 cm and make it evenly cover the bottom of the petri dish. After the solvent is completely evaporated, the content of circactin compound coated on the bottom of the petri dish is 1.0 μg / cm 2 . Add 13 mL of filter-sterilized seawater.

[0034] Control group: Add 1 mL of solvent methanol to make the solution evenly distributed on the bottom of the petri dish. After the solvent is completely evaporated, add 13 mL of filtered and sterilized seawater.

[0035] Blank group: Add 13 mL of filtered and sterilized seawater.

[0036] Determination of the number of larvae: Take the water body containing the larvae of the emerald mussel vectoli from the nursery pond and concentrate it with sieve silk. Take 50 mL each for three times, add 1-2 drops of formalin solution to kill the larvae, and then cou...

Abstract

The invention discloses the application of a cyclin compound in the preparation of a marine fouling biological control agent. The structural formula of the cyclin compound is shown in formula (I). When the ricibectin compound of the present invention is coated on a solid surface in a low dose, it can obviously inhibit the adhesion of marine organisms, so it can be used to prepare marine fouling biological control agents. And it is a naturally occurring organic compound, which will not pollute the water environment and cause its enrichment in organisms through the food chain. It is environmentally friendly and has high safety. It does not contain copper and tin while effectively inhibiting the adhesion of marine organisms. Heavy metal elements such as heavy metals have good social benefits from the perspective of environmental protection, have great potential for popularization and application, and have good application prospects in marine biofouling control. Formula (Ⅰ).

Description

technical field [0001] The invention belongs to the technical field of natural products, and in particular relates to the application of a cyclin compound in the preparation of marine fouling biological control agents. Background technique [0002] Marine fouling organisms refer to all kinds of organisms that fix or inhabit the underwater parts of ships and marine facilities. The hazards caused by them are mainly increased resistance, reduced speed, increased fuel consumption and CO 2 Discharge; block the seawater pipeline system, change the metal corrosion process, cause local corrosion or perforation corrosion; increase the dynamic load effect, cause drift, imbalance or even overturn of the facility; compete with breeding objects (such as shellfish) for attachment base and bait, hinder Its growth and development will reduce the quality of the product. [0003] Antifouling coatings are one of the most widely used technical methods in marine fouling biocontrol. However, tr...
