This invention relates to the field of pharmaceutical science, specifically to a sea anemone polypeptide, its preparation method, and its applications. The sea anemone polypeptide has the N-terminal sequence YPDQKMFELFWLEENNA, a molecular weight of 6027 Da, and an isoelectric point of 7.25. Preparation process: Fresh sea anemone is precipitated with 10%-70% acetone. After dialysis to remove salt from the active component, it is purified by ion exchange chromatography, gel filtration chromatography, and HPLC to obtain a sea anemone polypeptide with a molecular weight of 6027 Da. Experiments on tumor cells confirm that the sea anemone polypeptide has a significant inhibitory effect on the growth of various tumor cells but no inhibitory effect on the growth of normal cells.

The present application belongs to the technical field of water treatment, and particularly relates to a self-assembled sea anemone-like nanoflocculant and a preparation method thereof. The present application first prepares an aliphatic-quaternary ammonium / imidazole-silicon aluminum complex, utilizes the characteristics of long alkyl chain hydrophobicity and double cation hydrophilicity, forms a "core-shell" structure micelle through self-assembly, and then forms an intelligent sea anemone-like nanoflocculant solid through freeze-drying. The self-assembled sea anemone-like nanoflocculant removes the suspended solids and colloids through the "core-shell" structure, wherein the "shell" part is an inorganic flocculant, the "core" part is an organic flocculant, and the "shell" part is dissolved to remove the suspended solids and colloids and drive the outward turning of the organic functional groups of the "core" part, like the tentacles of sea anemones capturing water-soluble organic matters.

The present application provides a kind of purple spot sea anemone polypeptide toxin HC-G02 and its synthesis method, application, its amino acid sequence is APCSGCYYQVGNECVYDKLKC-NH2. Linear peptide HC-G02 is synthesized by adopting polypeptide solid-phase synthesis method, and the purity of linear peptide after purification reaches more than 95%. Purple spot sea anemone oxidized peptide HC-G02 (the connection mode of disulfide bond is C1-C3, C2-C4) is obtained by site-directed oxidation. The present application is found through hot plate experiment test that purple spot sea anemone oxidized peptide HC-G02 has good analgesic effect on physical pain of mouse, and the pain threshold of mouse intraperitoneal injection oxidized peptide HC-G02 is gradually increased in 30min, and the pain threshold reaches the highest in 120min after administration. The analgesic effect of oxidized peptide HC-G02 at 50mg / kg is equivalent to the analgesic effect of tramadol at the same concentration, and the analgesic time is prolonged.

The invention relates to an aptamer for specifically recognizing tetrodotoxin and application of the aptamer, and belongs to the technical field of detection. The cyclic divalent aptamer disclosed by the invention has good affinity and specificity and good thermal stability, is not interfered by impurities such as ion strength and protein in globefish meat and serum during tetrodotoxin detection, and has high conformational stability. Based on the annular bivalent aptamer, the invention further designs an aptamer sensor based on a 3D-DNA walker, the aptamer sensor can specifically detect low-concentration tetrodotoxin, the detection limit is 0.02 ng / mL, the detection time is 1 h, and the detection sensitivity is high. Other marine toxins such as gonyautoxin (GTX), dinophysiotoxin (DTX), sea anemone toxin II (ATX-II), anabaena toxin-a (ATX-a) and microcystin (MC-LR) cannot be detected, and the specificity is good.

The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, and particularly relates to cultivation soil for thunberg fritillary bulb and a preparation method of the cultivation soil. Comprising the following steps: preparing marine bioactive zymolyte; preparing a bran coat fungus fermentation product; and compounding and curing a cultivation soil matrix. Starfish and sea anemone in a specific proportion are selected as raw materials, special protein, active peptide, saponin and marine mineral substances which are rich in the raw materials are utilized, glutathione is added to protect neutral protease, chitinase and alginate lyase, directional enzymolysis is carried out under mild conditions, small-molecule active peptide with a biological stimulation function is released to the maximum extent, and the biological stimulation effect is achieved. The small molecule peptides can simulate plant signal molecules or serve as precursor substances, specifically activate expression and activity of key enzymes of alkaloid synthesis routes in thunberg fritillary bulb bodies, and can greatly increase the content of alkaloid in thunberg fritillary bulb and improve the medicinal effect of thunberg fritillary bulb after being added into cultivation soil.
