preparation example Construction

[0051] The present invention also provides a preparation method of the above-mentioned aporphine alkaloids. The method comprises preparing said compound from a plant of the genus Ivy, such as Ivy cordifolia. Preferably, the aporphine alkaloids are prepared from the roots, stems, leaves and fruits of Ivy cordifolia. Preferably, the method has the steps of:

[0052] (1) Crush the dried root of Ivy radiata to obtain root fragments of Ivy radiata;

[0053] (2) Soak the fragments of Ivy cordifolia root in a solvent to obtain an extract;

[0054] (3) Filter the extract and concentrate under reduced pressure to obtain the extract;

[0055] (4) Disperse the extract in water, sequentially extract with petroleum ether, ethyl acetate and n-butanol, and after the extract is distilled under reduced pressure, obtain petroleum ether extract, ethyl acetate extract, and n-butanol respectively. Butanol extract part of the extract;

[0056] (5) Part of the extract extracted with ethyl aceta...

Embodiment 1

[0064] Example 1 Inhibitory activity of the plant extract of Ivy cordifolia on the attachment of barnacle larvae

[0065] Source of material: Ivy with heart leaves was collected in Luquan, Yunnan, and was identified as Uraria clarkei (Clarke) Gagnep. The specimen is preserved in the Herbarium of the School of Medicine for Nationalities, Yunnan University for Nationalities.

[0066] The preparation of the extract of Ivy cordifolia: crush the dried root of Ivy cordifolia to obtain the root fragments of Ivy cordifolia root respectively; then extract the fragments of the root of Ivy cordifolia root with volume 90% ethanol reflux for 3 times, each time for 2 hours to extract solution; the extract of Ivy cordifolia was filtered separately and concentrated under reduced pressure with a rotary evaporator to obtain an extract for later use.

[0067] Using an experimental model of inhibition of barnacle Venus larvae attachment (see scientific literature: Xu Y., He H. P., Qian P. Y, et...

Embodiment 2

[0072] Embodiment 2 further test with Ivy

[0073] Further experiments were performed with the roots of the Ivy plant. This is not to imply that other plants of the Ivy genus are not active.

[0074] Respectively use 70% acetone / water, 80% ethanol / water and 90% methanol / water as extraction solvents by volume percentage, and repeat Example 1. The results are shown in Table 2. The experimental results show that 70% acetone extract of Ivy cordifolia root and 80% ethanol extract of Ivy cordifolia root obtained respectively with 70% acetone / water, 80% ethanol / water and 90% methanol / water as extraction solvents It has the same significant anti-biofouling activity as the 90% methanol extract of Ivy cordifolia root, so using different concentrations of acetone / water or ethanol / water or methanol / water as the extraction solvent can also obtain the anti-biofouling activity in Ivy cordifolia active ingredient.

Abstract

The invention discloses application of aporphinoid alkaloids. The application of the aporphinoid alkaloids includes applying the aporphinoid alkaloids to preparing antifouling paint. The application of the aporphinoid alkaloids has the advantages that the shortcomings of marine bio-fouling prevention in the prior art can be pertinently overcome, the problems of difficulty in applying marine antifouling paint, low effective rate, pollution due to the toxicity of the marine antifouling paint and the like in the prior art can be pertinently solved, three types of non-toxic aporphinoid alkaloids with obvious antifouling activity can be isolated and identified from illigera cordata of illigera plants of hernandiaceae, and the illigera cordata is a natural product; the problems in the prior art can be solved by the aid of the application of the aporphinoid alkaloids to preventing marine bio-fouling, the antifouling paint for preventing the marine bio-fouling, a method for preparing the antifouling paint and methods for preventing the surfaces of underwater structures from being attached and / or fouled by marine organisms.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to the application of aporphenanthrene alkaloids. Background technique [0002] With the increase of human ocean activities, the harm of marine fouling organisms has been paid more and more attention by human beings. Marine fouling organisms are harmful organisms that reproduce on the bottom of ships, underwater pipelines, oil platforms, fishing nets, and the surfaces of all other man-made facilities in the sea. They are mainly divided into three categories: fungi, attached plants, and attached animals. Its representative species are bacteria, fungi (fungi), silk algae, diatoms, enteromorpha, Ulva (plants), barnacles, mussels, lime worms, sea squirts, oysters, bryozoans, polyps (animals) species), etc., and the ones that have the greatest impact on ships are silk algae, enteromorpha, barnacles, limeworms, bryozoans, sea squirts, etc. Once marine fouling organ...
