Fraction B of Sargassum Heinzii Ethyl Acetate Extract and Its Preparation Method and Application in Biocontrol of Marine Fouling

Abstract

The invention discloses an ethyl acetate extract separated component B of Sargassum henslouianum and its preparation method and application in marine fouling biological prevention and removal. The ethyl acetate extract separated component B of Sargassum henslouianum in a low dosage coats the surface of the solid and has an obvious effect of inhibiting the attachment of the barnacle and the mussellarvae, and thus the ethyl acetate extract separated component B can be used for preparation of a marine fouling biological prevention and removal agent. The ethyl acetate extract separation componentB of Sargassum henslouianum is selected from Sargassum henslouianum, is a natural organic compound, does not pollute the water environment, is transported through the food chain to cause its enrichment in the organism, is environmentally friendly and safe, effectively inhibits the attachment of marine organisms, does not contain heavy metal elements such as copper and tin, has good social benefits from the perspective of environmental protection, and has a wide range of sources, is easy to separate and prepare, is suitable for large scale production, has a large promotion potential and has agood application prospect in marine fouling biological prevention and removal.

Description

Technical field:

[0001] The invention belongs to the field of natural products, and in particular relates to the separation component B of ethyl acetate extract of Sargassum henzii and its preparation method and application in marine fouling biological control. Background technique:

[0002] Marine fouling organisms refer to all kinds of organisms that fix or inhabit underwater parts of ships and artificial facilities and have adverse effects on human economic activities. The metal corrosion process causes corrosion and perforation; increases the dynamic load effect, causing man-made facilities to drift, unbalance or even overturn; competes with breeding objects for attachment substrates and bait, hinders their growth and development, and reduces the quality of aquatic products. Therefore, in the process of developing the marine economic industry, marine fouling biological control is always an indispensable and important part.
