This invention belongs to the field of cosmetic raw material preparation technology, specifically relating to a method for preparing a low-odor Xinjiang Lithospermum extract, its product, and its application. The method includes: raw material pretreatment: drying and pulverizing Xinjiang Lithospermum raw material to obtain pretreated material; first-stage extraction: loading the pretreated material into a supercritical fluid extraction device, adding a composite entrainer for extraction, and collecting the first fraction in a first separator; second-stage extraction: collecting a second fraction rich in naphthoquinone components in a second separator; and post-treatment: concentrating the second fraction and removing the alcohol solvent to obtain the low-odor Xinjiang Lithospermum extract. This invention can separate and discard most of the odor-causing volatile components in the raw material under mild conditions in the first stage, and then efficiently extract the core active substances of naphthoquinone in the second stage, achieving a significant reduction in the odor of the extract and a significant improvement in its sensory quality.

This invention relates to the field of new energy materials technology, and particularly to a high-entropy oxide particle, its preparation method, and its application. The invention involves mixing a polyacrylonitrile solution and a metal precursor to obtain a mixed liquid; spraying the mixed liquid into droplets and injecting it into water to obtain composite particles; drying the composite particles and then heat-treating them in air to obtain a microsphere-shaped metal precursor; calcining the microsphere-shaped metal precursor to obtain high-entropy oxide particles. This method is simple and scalable, meets the synthesis requirements of various high-entropy systems, and the resulting micro-regions are easy to refine with uniform elemental proportions, without introducing any impurities. It overcomes the problems of high cost, impurity introduction, and complex processes associated with traditional oxide material synthesis.

This invention relates to the field of sodium-ion battery technology, specifically disclosing a sodium iron pyrophosphate (NFPP) cathode material, its preparation method, and its application. The preparation method includes: using iron phosphate as the iron source, mixing it with a specific sodium source, phosphorus source, and composite carbon source; adjusting with deionized water; and then performing precision sand milling to control the slurry particle size D50 within 0.30~0.35 μm to ensure uniform elemental mixing; subsequently, spray drying is performed to obtain a precursor with high sphericity and narrow particle size distribution; finally, programmed sintering is carried out under an inert atmosphere to obtain the final product. This invention solves the problems of uneven elemental distribution, impurity phase formation, low material compaction density, and poor electrochemical performance in existing technologies through synergistic optimization of the entire process chain of sand milling-spray drying-sintering. The obtained NFPP material has a high-purity phase structure. The sodium iron pyrophosphate cathode material prepared by the method of this invention can achieve a 0.1C discharge specific capacity of 101 mA·hg. ‑1 The 1C discharge specific capacity can reach 93 mA·hg ‑1 It is suitable for the preparation of high-performance sodium-ion batteries.

The present application takes rare ginsenoside as raw material, introduces a sulfate group by sulfating modification on the rare ginsenoside to obtain a chemically modified rare ginsenoside derivative; the modifier used in the sulfating modification is a sulfonating agent. The rare ginsenoside is synthesized by conversion with ginsenoside Rb1 as raw material and AlCl3 as catalyst in an ethanol system. The modification method of the present application is simple in operation steps, does not require special equipment, is suitable for large-scale production, and has a broad application prospect in the field of drug preparation development and the like.

This invention discloses an anti-aging composition and its application in skincare products. The composition comprises lentil seed extract and β-nicotinamide mononucleotide; the anti-aging composition is prepared by a two-step process: aerobic fermentation with *Aspergillus oryzae* followed by anaerobic fermentation with *Bifidobacterium*. This invention achieves synergistic anti-aging effects by significantly inhibiting matrix metalloproteinase activity and promoting type I collagen synthesis through a multi-pathway synergistic effect of "anti-inflammatory, anti-oxidative, repair-energy-supply." The composition has high bioavailability, is mild and safe, and its preparation process is green and stable, making it suitable for skincare products such as creams and serums.
