The present invention addresses the problem of providing a method for reducing the iminosugar content in silkworm powder. The method that solves this problem is characterized by comprising a step for obtaining an extraction residue extracted from processed silkworms by using a nonpolar organic solvent.

A method for selectively leaching valuable metals from spent ternary lithium-ion battery cathode materials using an amino sugar eutectic solvent relates to the field of hydrometallurgy, providing an efficient method for extracting valuable metals from spent lithium-ion batteries. The hydrophilic eutectic solvent provided in this application comprises D-glucosamine hydrochloride and betaine hydrochloride. Valuable metals in spent ternary lithium-ion battery cathode materials are leached using the aforementioned eutectic solvent. The eutectic solvent of this application uses inexpensive raw materials, is widely available, and has low preparation costs. The leaching method for valuable metals in spent ternary lithium-ion battery cathode materials of this application can replace traditional pyrometallurgical processes and hydrometallurgical processes using strong acids and alkalis as leaching agents, achieving a green and environmentally friendly goal.

A composition comprises: (i) at least one C-glycoside; (ii) at least one aminosugar; and (iii) at least one Inonotus obliquus extract. A non-therapeutic method for caring for keratin materials comprises applying said composition to the keratin materials.

Described herein is a general solution to 1,2-cis-amino-glycoside synthesis through an iron-catalyzed, exclusively 1,2-cis-selective glycal aminoglycosylation via cooperative atom transfer catalysis. Further described is a 1,2-cis-selective glycal aminoacyloxylation method for 2-amino saccharide synthesis. The methods are effective for a wide variety of glycosyl donors with consistently high stereoselectivity and excellent functional-group compatibility, which facilitates late-stage amino group incorporation for complex-carbohydrate and other biologially-related molecule synthesis.

The invention belongs to the technical field of biological medicines, and particularly relates to uridine-5 '-diphosphate polydeoxy diamino sugar as well as a preparation method and application thereof. According to the invention, uridine-5 '-diphosphate-N-acetyl-glucosamine is used as a substrate to prepare UDP-kasuramine and a new structural analogue UDP-3 ''-hydroxyl-kasuramine of the UDP-kasuramine. The compound can be used as a medical intermediate for preparing commercial agricultural and medical antibiotic kasugamycin and derivatives thereof without / with low toxic and side effects. The method is simple and convenient to operate, mild in condition, environment-friendly and relatively high in conversion rate, and has a good application prospect.
