To provide an oral composition that has a high astringent effect and high storage stability of berberine. [Solution] An oral composition comprising (A) component: berberine, (B) component: hinokitiol, and (C) component: isopropylmethylphenols, wherein the content of component (B) is 0.001 to 0.5% by mass relative to the total mass of the oral composition, and the ratio of the mass of component (C) to the mass of component (B), expressed as component (C) / component (B), is 0.01 to 10.

This invention discloses a berberine-dimethylaniline photosensitizer, its preparation method, and its application, belonging to the field of biomedical technology. The method involves sequentially reacting berberine with magnesium methyl bromide via Grignard addition, followed by bromomethylation with N-bromosuccinimide, and basic condensation with dimethylaminobenzaldehyde, then demethylating under high temperature and vacuum to obtain the active berberine-dimethylaniline. Finally, it undergoes weakly alkaline treatment to obtain the inactivated berberine-dimethylaniline. This invention introduces the electron-donating group dimethylaniline onto the berberine backbone, constructing an electron push-pull structure that red-shifts the absorption wavelength, facilitating deeper tissue penetration. Furthermore, this photosensitizer maintains high activity in the weakly acidic microenvironment of tumors while remaining inactive under normal physiological conditions, thereby achieving intelligent "on-off" regulation based on pH differences, improving the safety and precision of photodynamic therapy for tumors.

The application discloses a composition for treating stubborn skin infection, ulcer and inflammation and a preparation method and application thereof, and belongs to the technical field of functional compositions. The composition is prepared from components containing baicalin 1-5 parts, antibacterial alkaloids 0.5-3 parts, asiaticoside 2-6 parts, salvianolic acid B 3-8 parts, gallic acid 1-4 parts, white plant polysaccharide 5-10 parts, konjac glucomannan 3-10 parts, chitosan 3-5 parts, glycerol 8-20 parts, genipin 0.5-2 parts, calcium chloride 1-3 parts, laurazepam 1-3 parts and water 40-80 parts. The antibacterial alkaloids include berberine or phellodendrine. The application scientifically matches the above components based on deep understanding of the stubborn skin pathological mechanism, and the composition exhibits a significant synergistic effect in in-vitro antibacterial, antibiofilm and anti-inflammatory experiments. The preparation process is simple, the cost is low, and the application is suitable for industrial production.

The application provides a pharmaceutical composition for treating gynecological inflammation and a preparation method thereof, and belongs to the technical field of medicines. After being subjected to water extraction and alcohol extraction, Sophora flavescens, Phellodendri chinensis, Forsythia suspensa and Ligustrum lucidum are used to obtain traditional Chinese medicine water extracts and traditional Chinese medicine alcohol extracts; the traditional Chinese medicine water extracts are reacted with silver salt and copper salt to obtain traditional Chinese medicine water extract-metal ion complex; the traditional Chinese medicine water extract-metal ion complex is mixed with the traditional Chinese medicine alcohol extracts, sodium taurodeoxycholate, laurocapram and berberine to prepare nanometer drug delivery micelles; and the nanometer drug delivery micelles are added into a hydrogel of chitosan, poloxamer P407 and poloxamer P188 to prepare the pharmaceutical composition for treating gynecological inflammation. The prepared composition has excellent treatment effect and low toxicity, thereby reducing the cost and improving the treatment effect of gynecological diseases such as chronic pelvic inflammatory disease, chronic cervicitis, vaginitis and artificial abortion complications, and has a wide application prospect.
