Embodiment 1

[0133]A 200 ml beaker was filled with 27.6 g of water, and then 60 g of NaOH solution (34.8%) was added thereto. Then, 60 g of dialdehyde carboxymethylcellulose (hereinafter referred to as DACMC) having a carbonyl group content of 0.94 mmol / g was added under stirring while maintaining the temperature not higher than 58°C. The reaction mass was stirred at room temperature for 3 hours, then the stirring was stopped and the reaction mass was aged for 18 hours until the carbonyl content reached 81.4% of the original polymer. The next day, the reaction mass was acidified with 10 g of sodium bicarbonate, stirred for 30 minutes, precipitated from acetone and dried. The yield of the resulting composition was 76.8 g.

Embodiment 2

[0135] A 200 ml beaker was filled with 70 g of NaOH solution (20%). Then, 7 g of DACMC with a carbonyl content of 2.3 mmol / g was added under stirring, and the reaction mass was stirred at 25°C for 60 minutes until the carbonyl content in the polysaccharide reached 26.5% of the original content, and then 23 g of sodium bicarbonate was added into the reaction mass and stirred for 30 minutes. Additionally, the reaction mass was precipitated from acetone and dried in a dry heat oven. The yield of the resulting composition was 39.2 g.

Embodiment 3

[0137] Fill a 200ml beaker with 70g of Na 2 CO 3 solution (20%). Then, 7 g of DACMC with a carbonyl content of 2.3 mmol / g was added under stirring, and the reaction mass was stirred at 25° C. for 180 minutes until the carbonyl content in the polysaccharide reached 62.2% of the original content. Additionally, the reaction mass was precipitated from acetone and dried in a dry heat oven. The yield of the resulting composition was 18.8 g.

Abstract

The present invention relates to an antimicrobial composition comprising a product of co-treatment of polyphenol and polysaccharide, and to a method for preparing the composition and an antiviral agent.

Description

technical field [0001] The present invention relates to the fields of organic chemistry and pharmaceuticals, and relates to antiviral and antimicrobial compositions comprising polyphenol / polysaccharide co-processed products, methods for preparing such compositions, and antiviral agents. Background technique [0002] Natural polyphenols are objects of increasing attention in the pharmaceutical industry due to their wide range of pharmacological activities and structural diversity (J. Agric. Food Chem., 58, 10016-10019, (2010)). [0003] In particular, it has antitumor activity (Cancer Res., 49, 3754-3758, (1989)), antiviral activity (Contraception, 39, 579-587 (1989)), antiparasitic activity (Science 218, 288- 289 (1982)) and antioxidant activity (J. Biol. Chem., 156, 633-642 (1944)). [0004] However, the disadvantages of polyphenols are their toxicity to reproductive system, heart and liver (Yin Juanjuan, ADissertation for the Degree of Doctor of Philosophy The Graduate Sc...
