Embodiment 1

[0014] (1) Preparation of the highly oxidized guaiacolide compound Menverins H-L of the present invention.

[0015] Cut 4 kg fresh samples of Gorgonian coral Menella sp. into pieces and soak them at room temperature in the order of alcohol→alcohol-dichloromethane (1:1 / V:V)→alcohol, soak for one week each time, and decompress the soaking solution (0.09 MPa, 40°C) after concentration, the concentrates are combined to obtain the extract after extraction.

[0016] Mix the extract obtained after extraction with twice the volume of pure water, extract three times with equal volume of ethyl acetate relative to the extract to obtain the ethyl acetate phase, and concentrate the extract under reduced pressure to obtain the ethyl acetate extract 7.21 g, while recovering the reagents.

[0017] Mix the ethyl acetate extract 7 with powdered silica gel, ventilate and dry it, grind it into powder, put it into a normal phase silica gel column by wet column method, choose to use CHCl 3 -Me 2...

Abstract

The invention discloses a preparation method of high oxidation guaiane-type compounds and an application of the compound for resisting marine biofouling. The invention provides five novel highly oxidized guaiane-type compounds separated by extracting from Menella kanisa, the structures of the compounds are shown as formula (1)-formula (5), which can be namely as Menverins H-L, and the compounds have attachment activity for resisting marine fouling organism Balanus amphitrite larvae.

Description

technical field [0001] The invention relates to the field of marine antifouling agents, in particular to a preparation method of a class of highly oxidized guaiac compounds and its application in preparing marine antifouling agents. Background technique [0002] In the vast ocean world, there are 2000-3000 species of fouling organisms, more than half of which live in coasts and harbors. In the historical process of developing and utilizing the ocean, human beings have been facing the problem of preventing marine fouling organisms from attaching, and the use of antifouling agents to make antifouling coatings is the most economically and technically feasible and effective means. TBT used to be the most effective antifouling coating, because it would interfere with the calcium metabolism of oysters, induce the distortion of gastropod marine animals, accumulate in fish, shellfish and other organisms, and have adverse effects on human health through the food chain, and have a neg...
