Problems solved by technology

Sea squirts often grow together in some marine aquaculture processes. Although sea squirts have the habit of being eaten as food in some areas, most of the sea squirts are still discarded as by-products in the breeding process, resulting in a lot of waste

Embodiment Construction

[0030] Below by embodiment the content of the present invention is specified:

[0031] 1) Freeze-dry the Ascidian ascidian with a wet weight of 10kg, cut it into pieces, crush it with a pulverizer and put it in a 5000mL beaker, use ethyl acetate to ultrasonically accelerate the leaching several times until the leaching solution is colorless, then combine the leaching Extract the liquid, dry the solvent with a rotary evaporator, and concentrate to obtain the crude extract (qe);

[0032] 2) 27.1 g of the crude extract (qe) obtained in step 1) was dissolved in methanol and separated by high-speed countercurrent liquid chromatography:

[0033] High-speed countercurrent liquid chromatography system TBE-300B; the solvent system is n-hexane: ethyl acetate: methanol: water = 1:1:1:1 (V / V), the four solvents are mixed and prepared in proportion, shake well, Ultrasound for 30 minutes to make it fully mixed, let it stand overnight to fully saturate the upper and lower phases, and separa...

Abstract

The invention discloses a method of separating a (E,E)-deca-3,7-diene-1-ol compound from styela plicata and a (E,E)-deca-3,7-diene-1-ol compound. Artificially bred styela plicata is taken as the raw material and the compound is separated from styela plicata. The raw material is easily available. Styela plicata can be fully recovered and utilized to avoid waste. High-speed countercurrent chromatography is adopted to carry out separation. The method has the advantages of no sample loss, no pollution, high efficiency, rapid separation, and large separation amount. Moreover, the separation steps are simple, and the operation is easy. The obtained novel compound namely (E,E)-deca-3,7-diene-1-ol has not been reported before, can be used as spice, and can be used to repel termites and insects. The method has an important meaning for the research on marine natural products.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation technology of biologically derived compounds, and in particular relates to a method for separating decadienol compounds from sea squirts and decadienol compounds thereof. Background technique [0002] There are more than 1500 species known in nature, mainly distributed in tropical and subtropical seas. Our country is rich in sea squirt resources. There are more than 100 species of sea squirts recorded in China's coastal areas, and many of them are unique to my country. According to reports, sea squirts contain a variety of compounds with anti-tumor, anti-virus, anti-bacterial, anti-inflammatory and other activities. Therefore, in recent years, the chemical composition and biological activities of sea squirts have become a hot field of research on marine natural products. [0003] Styela plicata is a kind of sea squirt, which is mainly distributed in Fujian, Guangdong and Hainan ...
