This invention discloses the application of *Pteris vittata* oil in skincare products. The preparation method of the *Pteris vittata* oil involves first extracting the raw material using supercritical CO2 extraction technology to obtain crude *Pteris vittata* oil; then purifying the crude *Pteris vittata* oil through multi-stage molecular distillation, collecting the light fraction to obtain the final *Pteris vittata* oil. This preparation method can efficiently enrich the antioxidant active ingredients such as tocopherols, squalene, and polyunsaturated fatty acids in the *Pteris vittata* oil. The prepared *Pteris vittata* oil exhibits excellent scavenging ability against DPPH free radicals, superoxide anions, and ABTS free radicals, while significantly enhancing SOD activity, reducing MDA levels, and minimizing oxidative stress damage, thereby exerting antioxidant and anti-aging effects. This provides a safe, gentle, and highly effective natural raw material for anti-aging, whitening, and skin barrier repair skincare products, and has promising market application prospects.

This invention discloses a garlic-flavored *Pteris vittata* strain and its application in ginseng-inspired crop rotation restoration and reduction of continuous cropping obstacles in *Gastrodia elata*, belonging to the field of agricultural biotechnology. The *Pteris vittata* strain MS-GY-GLY, with accession number CGMCC No. 42371, was isolated from ginseng rotation soil. This strain possesses multiple functions, including inhibiting pathogens, degrading allelopathic substances, and promoting *Gastrodia elata* growth, achieving microbial restoration of continuous cropping obstacles. Applying this strain to the *Gastrodia elata* cultivation system not only significantly reduces the content of various allelopathic substances in the soil and improves soil physicochemical properties, but also effectively suppresses soil pests, creating a favorable soil environment for *Gastrodia elata* growth. This invention combines this strain with Sichuan pepper extract and a specific cultivation substrate to construct a comprehensive technical system that can solve continuous cropping obstacles in *Gastrodia elata*, increase yield and efficacy, and provide technical support for the sustainable development of the *Gastrodia elata* industry.

This invention discloses a method for preparing EPA- and nervonic acid-enriched *Pteris vittata* oil, belonging to the field of fatty acid extraction technology. The method uses *Pteris vittata* as raw material, employing supercritical CO2 extraction to obtain crude oil, which is then enriched through enzymatic ester exchange and urea inclusion purification processes. Following solvent removal, decolorization, and deodorization, the EPA- and nervonic acid-enriched *Pteris vittata* oil is obtained. The *Pteris vittata* oil prepared by this invention contains ≥15g / 100g of EPA and ≥5g / 100g of nervonic acid, significantly promoting the synthesis and accumulation of phospholipids in the brain and exhibiting excellent repair and protection effects on nerve cells damaged by hydrogen peroxide. It can be widely used in the preparation of foods, health products, or pharmaceuticals that improve cognitive function, promote nerve repair, or maintain brain health.

This invention relates to the fields of biomedicine and health food, and particularly to a supercritical fluid-extracting, fat-soluble anti-aging soft capsule made from *Pteris vittata* (a type of insect) and its preparation method. The soft capsule has two formulation options, both using supercritical CO₂ extraction of *Pteris vittata* fat-soluble extract as the core ingredient. The first formulation combines curcumin and tanshinone compounds, supplemented with flaxseed oil, rosemary extract, and other components. The second formulation combines turmeric oil and tanshinone IIA, combined with wolfberry seed oil and licorice oil. The core active substances are obtained using supercritical CO₂ extraction, and after mixing according to the specified ratio, the mixture undergoes emulsification, filling, and drying to obtain the finished product. This invention's product exhibits significant antioxidant and anti-inflammatory effects, improves the absorption efficiency of fat-soluble components, is gentle and non-irritating to the gastrointestinal tract, and can improve chronic inflammation, skin aging, and cardiovascular-related risks. The preparation process is stable and controllable, possessing high industrial application value.

This invention discloses a lung-nourishing and vital energy-strengthening traditional Chinese medicine composition containing Cordyceps sinensis, saffron, and Pteris vittata, and its preparation method, belonging to the field of traditional Chinese medicine preparation technology. The method includes: cryogenically treating Cordyceps sinensis and saffron at -25℃ to -10℃ and adjusting their water activity to 0.20 to 0.30; high-energy ultrafine pulverization at -5℃ to 5℃ to a D95 ≤ 50μm; supercritical solidification at 25 to 35 MPa and 35℃ to 45℃; and finally, encapsulation with Pteris vittata polysaccharide powder. This invention, through the triple coupling of cryogenic treatment, water activity, and supercritical pressure, induces the formation of stable molecular complex structures of active ingredients, solving the problems of easy degradation, low solubility, and poor bioavailability of adenosine. The composition obtained by this invention shows an increase in adenosine solubility of more than 5 times, an enzymatic half-life extension of more than 20 times, and anti-inflammatory efficacy in a lung injury model superior to a large compound of 12 herbs, demonstrating significant clinical application prospects.

The present application belongs to the technical field of soil remediation, and relates to a method for remediation of arsenic contaminated soil by Pteridium aquilinum Linn. with biochar. The present application uses biochar, including one of straw biochar, iron modified biochar, aluminum modified biochar and iron-aluminum modified biochar; 1% to 2% of biochar is applied to the arsenic contaminated soil in terms of mass ratio, which strengthens the arsenic remediation capacity of Pteridium aquilinum Linn. to the soil, and improves the efficiency of Pteridium aquilinum Linn. in remediation of arsenic in the soil to 19.25% to 26.24%. The boundary use conditions of the technology for remediation of heavy metal contaminated soil by biochar strengthened plant are not clear, and the present application eliminates the prejudice or misunderstanding of ordinary technical personnel in the field, including researchers in the field, that the modified biochar is superior to the biochar for remediation of arsenic contaminated soil. The present application enables the practitioners in the field to have a more comprehensive understanding of the biochar, especially the metal modified biochar, for remediation of arsenic contaminated soil.
