A composition for forming a protective film for a wet etching solution for semiconductors, comprising: component (A): a film-forming component; component (B): a compound selected from the group consisting of a condensed tannin (b1) obtained by polymerizing a compound having a flavanol skeleton, a hydrolyzable tannin (b2) obtained by ester-bonding a sugar and an aromatic compound of gallic acid or ellagic acid, and a flavonoid (b3) derived from a compound having a flavanone skeleton structure; and component (C): a solvent.

The application belongs to the technical field of medicine, and particularly relates to a blood vessel targeting anti-aging oral composition and application thereof. In view of problems such as endothelial dysfunction, matrix sclerosis and accumulation of senescent cells caused by vascular aging, the composition comprises active ingredients: beetroot extract, fisetin, salvianolic acid B, panax notoginseng total saponins, cocoa flavanol, pterostilbene, procyanidin B2, luteolin, nicotinamide riboside and astaxanthin. The composition is prepared by a process of adsorbing astaxanthin on beetroot extract, mixing other active ingredients, fillers and glidants after fisetin and salvianolic acid B are prepared into a solid dispersion, and sequentially cooperating each module, so that the pulse wave transmission velocity can be significantly reduced and the skeletal muscle capillary density can be increased, and the composition is mainly used for preparing a medicine for improving vascular stiffness, promoting microcirculation and removing vascular senescent cells.

This invention relates to a polyphenolic compound extracted from *Pterocarya stenoptera* and its application in the preparation of drugs for inhibiting enteritis. The polyphenolic compound is the first to be isolated from *Pterocarya stenoptera*, and is a novel, stable, and naturally occurring flavan-3-ol dimer monomer, rather than a polymer degradation product. The preparation method can stably produce high-purity polyphenolic compounds, suitable for the large-scale preparation of novel active ingredients from natural products. Experiments have shown that the polyphenolic compound of this invention possesses intestinal barrier repair capabilities, can inhibit inflammatory factors in the intestinal environment, and is more effective than commonly used clinical drugs. Furthermore, it is naturally derived, highly safe, and has significant clinical application value.

The invention provides a solid biological bacterial fertilizer for rutaceae. The solid biological bacterial fertilizer is prepared by inducing probiotic expression of rutaceae plants, culturing and screening specific flora, and developing a bacterium-charcoal-plant triple interaction carrier based on pomace resource utilization: squeezing and pyrolyzing a pomace-rice hull mixture to prepare a charcoal carrier, and activating flora induction by flavanol; the composite bacterial liquid is wrapped by pectin-activated clay gel to form a soil response type slow release structure, and the solid biological bacterial fertilizer capable of improving rutaceous soil, the yield of agricultural products and the quality of fruits is obtained.

The invention discloses an SbLAC14 gene separated from sorghum as well as an encoding protein and application thereof, and belongs to the field of plant genetic engineering and molecular biology. The laccase gene SbLAC14 with a coding region nucleotide sequence as shown in SEQ ID NO.2 is separated from sorghum for the first time through multi-omics conjoint analysis. Functional verification experiment results show that overexpression of the SbLAC14 gene can improve the content of polymeric proanthocyanidins of wild type arabidopsis thaliana, deepen the color of seed coats, and also can completely recover the polymerization defect of proanthocyanidins of a tt10 mutant and the superficial type of the color of the seed coats, which proves that the SbLAC14 gene has the biological function of catalyzing flavane-3-alcohol monomer polymerization to form proanthocyanidins. The invention provides a gene resource and an operation target with important application value for plant procyanidine synthesis regulation and control, and can be used for tannin metabolic engineering and variety improvement.

The application discloses a new compound separated from haircap moss and a preparation method and application thereof, and belongs to the technical field of natural medicines. The preparation method comprises the following steps: step one, taking the dried haircap moss plants, crushing, extracting with 95% ethanol by heating and refluxing for at least 2 times, each time for at least 2 hours, filtering, combining the extraction liquid, and concentrating into thick extract under reduced pressure to obtain a crude extract; step two, dispersing the crude extract with hot water, and sequentially extracting with petroleum ether, dichloromethane, ethyl acetate and n-butanol; each polar part extraction liquid is concentrated under reduced pressure to obtain an extract; step three, gradient elution of the dichloromethane extract on an MCI column with a methanol-water solvent system; and step four, concentration of the 50% methanol eluent, and then preparation liquid phase, acetonitrile-water solvent isocratic elution. The new flavanol compound is separated from the haircap moss, has good anti-liver cancer activity, and lays a foundation for the development and utilization of the haircap moss plant resources.
