[0014] Preparation of Compounds of the Invention

[0015] (1) The medium used for the culture of the fungus Aspergillus sp. (HM535361) contains 1.0% glucose (percentage by weight, the same below), 0.1% yeast extract, 0.2% peptone, 1.0% agar, 3% coarse sea salt, and the rest is water , when used to make a test tube slant, fungal strains were cultured at 28 ° C for 5 days.

[0016] The strain medium contains 0.1%-5.0% of glucose (percentage by weight, the same below), 0.01%-1% of yeast extract, 0.01%-1% of peptone, 0.1%-3.0% of agar, and 0.1%-5% of coarse sea salt , and the rest is water. The culture temperature is 5-45° C., and the culture time is 3-10 days.

[0017] (2) Fermentation culture of the fungus Aspergillus sp. (HM535361) The fermentation medium used was rice solid medium, and 100 g of rice, 3 g of coarse sea salt, 0.6 g of peptone, and 100 mL of water were added to each 1000 mL Erlenmeyer flask. The fungal strains were grown at 28°C for 30 days.

Abstract

A preparation method of a diphenyl ether compound and application of the compound as a natural marine organism antifouling agent. The preparation method is as below: culturing marine fungus Aspergillus sp. (HM535361) in a fungus culture medium; conducting fermentation culture on the fungi in a fermentation medium; then soaking the fermentation products with methanol; conducting decompression concentration to obtain a methanol crude extract; suspending the extract in water; extracting the extract with ethyl acetate, conducting vacuum concentration on the extract and conducting chromatographic separation; and concentrating the eluent to obtain four colorless or light red oil, 4-methoxycarbonyl-diorcinol, 3, 3 '-O-dimethyl-violaceol-I, cordyolC and diorcinol. The invention provides an environment-friendly natural marine organism antifouling agent, which is characterized by using the diphenyl ether compound as an effective ingredient. The antifouling agent can be used for the prevention and treatment of marine organism biofouling caused by attachment of barnacle Balanus Amphitrite larvae, and has the advantages of high efficiency and low toxicity. The raw material can be obtained from mass production by fungal fermentation, and is not subjected to resource constraints; therefore, the invention has wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a diphenyl ether compound with the activity of inhibiting the attachment of barnacle larvae and its application as a natural marine biological antifouling agent. Background technique [0002] Marine biofouling is caused by the larvae of marine fouling organisms such as barnacles, mussels, and bryozoans attaching to and growing on the surface of marine facilities such as hulls, fish tanks, oil wells, or other marine organisms to form communities, thereby causing damage to the attached objects. Damage, such as accelerating metal corrosion, reducing the performance of marine facilities, affecting the output and quality of aquaculture, etc. Among marine fouling organisms, barnacles are the most widely distributed and most harmful. The economic loss caused by marine biofouling is huge every year all over the world. Taking ships as an example, marine organisms attach to the bottom of the ship, which increase...
