Embodiment 1

[0025] A preparation method of viola syringin with anti-inflammatory and antiseptic activity, comprising the following steps:

[0026] (1) Drying the residue of Viola radix remaining after alcohol extraction at 45° C., pulverizing it through a 50-mesh sieve to obtain Viola radix residue powder;

[0027] (2) Utilizing ultraviolet radiation to sterilize the residue powder of Viola radiata for 30 minutes;

[0028] (3) Add 3 times the weight of distilled water to the sterilized viola residue powder, add 0.05% cellulase and neutral protease with a mass ratio of 1:2, mix well, and place it in a constant temperature water bath at 55°C for 1.5 h;

[0029] (4) Add 5 times the amount of 70% ethanol to the residue powder of Viola chinensis, reflux extraction twice at 50°C for 35 minutes each time, vacuum filter under reduced pressure, concentrate, and vacuum dry to obtain Viola syringin.

Embodiment 2

[0031] A preparation method of viola syringin with anti-inflammatory and antiseptic activity, comprising the following steps:

[0032] (1) Put the residue of Viola radix remaining after alcohol extraction, dry it at 45°C, pulverize it through a 40-mesh sieve, and obtain the Viola radix residue powder;

[0033] (2) Utilizing ultraviolet radiation to sterilize the residue powder of Viola radiata for 30 minutes;

[0034] (3) Add 3 times the weight of distilled water to the sterilized viola residue powder, add 0.05% cellulase and neutral protease with a mass ratio of 1:2, mix well, and place it in a constant temperature water bath at 55°C for 1.5 h;

[0035] (4) Add 4 times the amount of 70% ethanol to the residue powder of Viola chinensis, reflux and extract twice at 50°C for 35 minutes each time, vacuum filter under reduced pressure, concentrate, and dry in vacuum to obtain Viola syringin.

Embodiment 3

[0037] A preparation method of viola syringin with anti-inflammatory and antiseptic activity, comprising the following steps:

[0038] (1) Drying the residue of Viola radix remaining after alcohol extraction at 45° C., crushing and passing through a 60-mesh sieve to obtain Viola radix residue powder;

[0039] (2) Utilizing ultraviolet radiation to sterilize the residue powder of Viola radiata for 30 minutes;

[0040] (3) Add 3 times the weight of distilled water to the sterilized viola residue powder, add 0.05% cellulase and neutral protease with a mass ratio of 1:2, mix well, and place it in a constant temperature water bath at 55°C for 1.5 h;

[0041] (4) Add 6 times the amount of 70% ethanol to the residue powder of Viola chinensis, reflux and extract twice at 50°C for 35 minutes each time, vacuum filter under reduced pressure, concentrate, and dry in vacuum to obtain Viola syringin.

Abstract

The invention discloses a Chinese violet coumarin with anti-inflammatory and antiseptic activity and a preparation method and application thereof. The preparation method of the Chinese violet coumarin with the anti-inflammatory and antiseptic activity comprises the following steps of (1) drying Chinese violet residues at 45 DEG C and crushing the dried Chinese violet residues into Chinese violet powder; (2) irradiating the Chinese violet powder under ultraviolet rays for 30 min for sterilization; (3) adding water, 3 times as much as the weight of the sterilized Chinese violet powder, into the sterilized Chinese violet powder, and then adding in complex enzymes, uniformly mixing and placing the mixture in a 55 DEG C thermostatic water bath for 1.5 h; (4) adding organic extracting agent into the Chinese violet powder and then performing reflux extraction twice for 35 min each time, and performing decompressed vacuum filtration, concentration and vacuum drying to obtain the Chinese violet coumarin. The prepared Chinese violet coumarin with the anti-inflammatory and antiseptic activity has broad-spectrum bacteriostatic, bactericidal and anti-inflammatory activity.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to viola syringarin with anti-inflammatory and antiseptic activity, its preparation method and application. Background technique [0002] In hot summer or after exercise, human skin will secrete a lot of sweat, plus dust and bacteria in the air will stick to the skin. If the sweat is not cleaned in time, it will breed a lot of bacteria. With the progress of society and the continuous improvement of office environment, more and more people can work in a comfortable air-conditioned environment. However, air-conditioned rooms can easily breed a large number of bacteria. These bacteria can cause unexplained infection of the skin, cause inflammation of the skin, and cause symptoms such as erythema and itching on the skin. This will affect people's external image, what's more, it can affect people's normal life. [0003] Viola chinensis is a perennial herb of the Viola family Viola genus, and ...
