This invention discloses a method for preparing capsaicin-like substances by temperature-responsive eutectic solvent extraction, comprising the following steps: drying Yunnan chili peppers (after removing stems and seeds), pulverizing, sieving, and collecting the chili powder; mixing lidocaine (HBA) with six alkane-chain carboxylic acids (valerate, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, and lauric acid) at a 1:1 molar ratio to form a homogeneous and transparent liquid, TRDES; weighing the chili powder, adding it to the TRDES aqueous solution, and extracting by shaking; after extraction, centrifuging, and diluting the supernatant to obtain capsaicin-like substances. This invention uses temperature-responsive eutectic solvent extraction to prepare capsaicin-like substances, which is simple, highly efficient, and allows for the recycling of extraction reagents, effectively saving resources. It has significant practical and industrial value for promoting the large-scale production of capsaicin-like substances and enhancing their high-value applications.

This invention relates to the field of supramolecular chemistry, specifically to a fluorinated functionalized macrocyclic supramolecular host molecular cup, its preparation method, and its applications. It is a 2-difluoromethylbenzimidazole molecular cup host and its metal derivatives. By introducing a difluoromethyl group to moderately increase lipophilicity, the excellent properties of the trifluoromethyl macrocyclic supramolecular host are inherited while increasing water solubility. Furthermore, it can recognize cycloalkanes, alkyl carboxylic acids, especially n-heptanoic acid and n-octanoic acid, thus facilitating a series of molecular recognition studies in aqueous phase. Compared with existing technologies, this invention features a simple process, readily available raw materials, mild reaction conditions, high yield, and good reproducibility. The difluoromethyl-modified macrocyclic molecular cup H1 and the metal molecular cup H formed with palladium in this invention are also described. 1‑Pd It exhibits novel structure and high degree of functionalization, enhancing its molecular recognition ability and selectivity, and can be used in environmental remediation and water pollutant treatment.

Various aspects disclosed relate to an antiperspirant composition. The antiperspirant composition includes an isododecane component; an alkyl benzoate component; and a neopentyl glycol diheptanoate component.

This invention relates to a method for synthesizing (S)-3-methylheptanoic acid, which further expands the application scope of steroidal saponin degradation waste. The method of this invention conveniently synthesizes (S)-3-methylheptanoic acid from (R)-γ-methyl-δ-butyrate lactone obtained from the degradation of steroidal saponins. The method provided by this invention is simpler and more efficient than existing methods. It also helps to improve the utilization rate of steroidal saponin resources and reduce the generation of waste during their utilization.

Provided herein is a method of treating a patient having pyruvate dehydrogenase complex deficiency (PDCD), including administering to the patient an amount of triheptanoin effective to treat PDCD in the patient.

The application relates to the field of material chemical synthesis, in particular to a synthesis method of large-size colloidal gold microspheres, which comprises the following steps: dissolving oleylamine and chloroauric acid in toluene, heating to boiling and continuously reacting for 3 hours, adding ethanol for precipitation after cooling to room temperature, centrifuging to obtain oil-phase colloidal gold nanoparticles OA-AuNPs, and redissolving with toluene to obtain OA-AuNPs toluene solution; mixing and dissolving the OA-AuNPs toluene solution obtained in the step S1 with distearoyl phosphatidyl ethanolamine-polyethylene glycol-n-heptanoic acid, adding sodium dodecyl sulfate SDS aqueous solution, and forming a microemulsion through ultrasonic emulsification. The synthesis method is efficient, easy to prepare and stable in performance; the prepared large-size colloidal gold microspheres are large in loading capacity, excellent in colorimetric characteristics, strong in stability, have rich functional groups on the surface which can be directly coupled with proteins, and overcome the related defects of traditional colloidal gold.
