Embodiment 1

[0026] A preparation method of tomato leaf extract, comprising the following steps:

[0027] Step 1, crushing: crushing the dried tomato leaves to 100 mesh;

[0028] Step 2, crude extraction: prepare an aqueous solution of sodium bisulfite with a mass fraction of 0.1%, and then add ethanol until the volume concentration of ethanol is 30%, to obtain a solution. Add the solution to the crushed tomato leaf material in step 1, the mass ratio of the crushed material to the solution is 1:10-1:20, extract at 60-90°C for 4-6 hours, and repeat the extraction three times;

[0029] Step 3, filter and dry: cool the crude extract in step 2 to 20-30°C, filter out insoluble matter with a filter cloth of 1000-2000 mesh, and concentrate under reduced pressure to 1 / 5 to 1 / 10 of the volume of the extract in step 2 , and then vacuum-dried to obtain dry matter;

[0030] Step 4. Dissolving and refining: add the dry matter obtained in step 3 to 1,3-butanediol, the mass volume ratio of dry matter t...

Embodiment 2

[0033] A preparation method of tomato leaf extract, comprising the following steps:

[0034] Step 1, crushing: crushing the dried tomato leaves to 100 mesh;

[0035] Step 2, crude extraction: prepare an aqueous solution of sodium bisulfite with a mass fraction of 0.3%, and then add ethanol until the volume concentration of ethanol is 50%, to obtain a solution. Add the solution to the crushed tomato leaf material in step 1, the mass ratio of the crushed material to the solution is 1:10-1:20, extract at 60-90°C for 4-6 hours, and repeat the extraction three times;

[0036] Step 3, filter and dry: cool the crude extract in step 2 to 20-30°C, filter out insoluble matter with a filter cloth of 1000-2000 mesh, and concentrate under reduced pressure to 1 / 5 to 1 / 10 of the volume of the extract in step 2 , and then vacuum-dried to obtain dry matter;

[0037] Step 4: Dissolving and refining: add 1,3-butanediol to the dry matter obtained in step 3, the mass volume ratio of dry matter t...

Embodiment 3

[0039] A preparation method of tomato leaf extract, comprising the following steps:

[0040] Step 1, crushing: crushing the dried tomato leaves to 100 mesh;

[0041] Step 2, crude extraction: prepare an aqueous solution of sodium bisulfite with a mass fraction of 0.5%, and then add ethanol until the volume concentration of ethanol is 40%, to obtain a solution. Add the solution to the crushed tomato leaf material in step 1, the mass ratio of the crushed material to the solution is 1:10-1:20, extract at 60-90°C for 4-6 hours, and repeat the extraction three times;

[0042] Step 3, filter and dry: cool the crude extract in step 2 to 20-30°C, filter out insoluble matter with a filter cloth of 1000-2000 mesh, and concentrate under reduced pressure to 1 / 5 to 1 / 10 of the volume of the extract in step 2 , and then vacuum-dried to obtain dry matter;

[0043] Step 4. Dissolving and refining: add the dry matter obtained in step 3 to 1,3-butanediol, the mass volume ratio of dry matter t...

Abstract

The invention discloses a tomato leaf extract and application thereof in cosmetics. The tomato leaf extract is prepared by the followings: step (1) pulverization: pulverizing dried tomato leaves to 100 meshes powder; step (2) crude extraction: preparing an aqueous solution containing sodium bisulfite, adding ethanol to obtain solution, adding the solution into the pulverized tomato leaf powder obtained in step (1) at a material-to-solution mass ratio of 1:(10-20), extracting at 60-90DEG C for 4-6h, and repeating extraction three times; step (3) filtering and drying: cooling crude extract obtained in step (2) to 20-30DEG C, filtering with 1,000-2,000 meshes filter cloth to remove insoluble substances, concentrating under reduced pressure to 1 / 5-1 / 10 of the volume of the extractive solution obtained in step (2), and performing vacuum drying to obtain dry substance; and step (4): dissolving and refining: adding the dry substance obtained in step (3) into a solvent at a mass ratio (dry substance to solvent) of 1:5, standing at a low temperature for 1-2 days, centrifuging in a centrifuge at a rotation speed of 5,000rpm for 30 min, and collecting supernatant to obtain refined tomato leaf extract. The tomato leaf extract obtained by the preparation method disclosed by the invention has high content of active ingredients, and can be added in cosmetics to take effects of nourishing skin and resisting wrinkles.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a tomato leaf extract and its application in cosmetics. Background technique [0002] Plant skin care is a trend that has emerged in recent years. After cosmetics have experienced synthetic petrochemical-derived chemicals, they are now returning to nature. People are beginning to look for functional substances in natural plants that can make the skin healthy and vibrant. [0003] Tomato, also known as tomato, belongs to the Solanaceae family and is native to South America. It is widely cultivated in the north and south of my country, and Xinjiang has the largest output. As we all know, tomato fruit contains vitamins and other antioxidant ingredients, which have beauty and anti-wrinkle effects when applied in cosmetics. However, the leaves of tomato have not been fully researched and developed. After the tomato ripe fruit is picked every year, the tomato plant will be discarded without f...
