Embodiment 1

[0035] Weigh aescin powder into a screw bottle, add 1mL of 0.1M PBS buffer solution (pH=8.0-12.0) or 1mL of 0.1M NaOH (or KOH) solution, raise the temperature to 50°C, and sonicate for 8min to make It is completely dissolved to obtain an aescin solution, the concentration of the aescin is 1.0%wt, and the aescin injectable hydrogel is obtained after standing at room temperature for 5 hours.

[0036] A digital camera was used to record the appearance of the escin injectable hydrogel. figure 1 It is the appearance diagram of aescin injectable hydrogel. Such as figure 1 As shown, the appearance of the aescin injectable hydrogel is colorless, uniform and transparent jelly-like.

Embodiment 2

[0038] Weigh aescin powder into a screw bottle, add 1mL of 0.1M PBS buffer solution (pH=8.0-12.0) or 1mL of 0.1M NaOH (or KOH) solution, raise the temperature to 60°C, and sonicate for 4min to make It is completely dissolved to obtain an aescin solution, the concentration of the aescin is 1.5%wt, and the aescin injectable hydrogel is obtained after standing at room temperature for 3 hours.

Embodiment 3

[0040] Weigh aescin powder into a screw bottle, add 1mL of 0.1M PBS buffer solution (pH=8.0-12.0) or 1mL of 0.1M NaOH (or KOH) solution, raise the temperature to 70°C, and sonicate for 3min to make It is completely dissolved to obtain an aescin solution, the concentration of the aescin is 2.0%wt, and the aescin injectable hydrogel is obtained by standing at room temperature for 1 hour.

Abstract

The invention discloses an aescin injectable hydrogel, and a preparation method and application thereof. The aescin injectable hydrogel is a hydrogels formed by self-assembly of aescin in an alkalineaqueous solution, and the preparation method is to dissolve aescin in the alkaline aqueous solution and then perform standing. The aescin injectable hydrogel has performance of shear thinning and self-repairing, does not need chemical modification and auxiliary additives, does not need additional drug carrier materials, and can be injected for administration directly. The aescin injectable hydrogel is good in sustained release, high in drug utilization, high in safety and good in therapeutic effect, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of aescin preparations, in particular to an injectable hydrogel of aescin and its preparation method and application. Background technique [0002] Hydrogel is a gel with water as the dispersion medium, and its appearance is semi-solid like jelly. Traditional hydrogels are formed by cross-linking polymer chains to form a three-dimensional network structure, and the three-dimensional network structure binds a large amount of water. Different from traditional hydrogels, small-molecule hydrogels are formed by self-assembly of small molecules in water using non-covalent bonds. They have the advantages of good biocompatibility, easy degradation, and fast absorption. They are used in drug delivery, cell culture, Tissue engineering and other biomedical fields have broad application prospects. [0003] Most of the clinically used drugs exist in the form of oral capsules or tablets, but some drugs have problems suc...
