However, the rosin existing in nature is blocky and attached to the tree, the texture is relatively hard, and the color is a brown solid. When it dissolves in various solvents, it tends to crystallize, and a part of it will be precipitated to form flocs or precipitate small. Particles, thus affecting the antibacterial effect of rosin

Embodiment 1

[0022] A kind of rosin solution bacteriostasis agent, described rosin solution refers to the solution of rosin in the ethanol aqueous solution that has added alkaline substance, wherein alkaline substance selects Na 2 CO 3 , the preparation method is as follows: Grind the rosin block into powder, add it into pure water, and stir well until a grass-green liquid A is formed; add solid Na 2 CO 3 , fully stirred until forming liquid B with no obvious change in color; adding absolute ethanol to liquid B, fully stirring until a dark brown solution was formed, and grinding the solution to obtain the rosin solution bacteriostatic agent.

Embodiment 2

[0024] A kind of rosin solution bacteriostasis agent, described rosin solution refers to the solution of rosin in the ethanol aqueous solution that has added alkaline substance, and wherein alkaline substance selects NaHCO for use 3 , the preparation method is as follows: grind the rosin block into powder, add it into pure water, and stir well until a grass-green liquid A is formed; add solid NaHCO into the A liquid 3 , fully stirred until forming liquid B with no obvious change in color; adding absolute ethanol to liquid B, fully stirring until a dark brown solution was formed, and grinding the solution to obtain the rosin solution bacteriostatic agent.

[0025] (1) Taking Example 1 as an example, by changing the volume ratio of water and ethanol and Na 2 CO 3 Adding amount, explore the dissolving effect of rosin in the rosin solution bacteriostatic agent, obtain the following table:

Abstract

The invention discloses a rosin dissolution liquid bacteriostatic agent and a preparation method and application thereof. The rosin dissolution liquid is a dissolution liquid of rosin in an ethanol aqueous solution mixed with alkaline matter. The rosin dissolution liquid bacteriostatic agent and the preparation method and application thereof have the advantages that the rosin in the rosin dissolution liquid bacteriostatic agent is quick in dissolution rate and large in dissolution amount, and the rosin dissolution liquid bacteriostatic agent has a better bacteriostatic effect, particularly hasa significant inhibiting effect on staphylococcus aureus, basically has no toxic and side effects on the human and animal bodies, can generate natural plant aroma, also has a certain converging effect, can serve as a safe and effective ideal bacteriostatic additive, and is especially suitable for being used as an animal feed additive.

Description

technical field [0001] The invention relates to the technical field of antibacterial agents and biological feed, in particular to a rosin solution antibacterial agent and its preparation method and application. Background technique [0002] Rosin is a renewable natural dominant biomass resource in my country, and its main component is diterpene resin acid with a phenanthrene ring skeleton. Rosin resin acid derivatives have a wide range of biological activities, such as antibacterial properties, and have important uses in medicine and pesticides. However, the rosin existing in nature is blocky and attached to the tree, the texture is relatively hard, and the color is a brown solid. When it dissolves in various solvents, it tends to crystallize, and a part of it will be precipitated to form flocs or precipitate small. Particles, thus affecting the antibacterial effect of rosin. Contents of the invention [0003] The object of the present invention is to provide a rosin sol...
