Plant extract composition with conditioning effect on skin care and preparation method thereof

Abstract

The invention belongs to the field of technologies for preparing natural plant products, and particularly relates to a plant extract liquid composition with skin protecting and conditioning functions and a method for preparing the plant extract liquid composition. The method includes steps of S1, respectively soaking selaginella lepidophylla, sargassum, radix et rhizoma rhodiolae, herba centellae, rhizoma zingiberis recens, chamomile, herba portulacae and flos lonicerae in ethyl alcohol solution for 4 h and then carrying out reflux extraction under the condition of the temperature of 80 DEG C to obtain extract liquid of various raw materials; S2, mixing the extract liquid of the various raw materials to obtain mixed liquid, adding modified chitosan flocculating agents into the mixed liquid, stirring the modified chitosan flocculating agents and the mixed liquid for 20-30 min to obtain mixtures, then allowing the mixtures to stand still for 2-3 h and filtering the mixtures to obtain clear liquid; S3, carrying out ultra-filtration on the clear liquid to obtain trapped liquid which is the plant extract liquid composition with the skin protecting and conditioning functions. The plant extract liquid composition and the method have the advantages that various impurities such as fine particles, mucusl matters, proteins and tannin in plant crude extract liquid can be effectively removed by the aid of the method, accordingly, the stability of systems can be greatly improved, effective components are high in retention ratio, and obvious skin protecting and conditioning effects can be realized by the plant extract liquid composition prepared by the aid of the method.

Description

technical field [0001] The invention belongs to the technical field of plant natural product preparation, and more specifically relates to a plant extract liquid composition with skin care conditioning effect and a preparation method thereof. Background technique [0002] Resurrection grass is a desert plant known for its ability to "resurrect" when almost completely dried out. In the case of extreme drought, its branches and leaves will shrink tightly into a ball, firmly lock the last drop of precious water in the body, even if it loses up to 98% of its own water, it can still survive tenaciously for decades, this is because the resurrection grass The body is rich in glycosyl trehalose, which can exert a powerful water-locking and moisturizing function, and then introduce the water containing vitality into every cell in the body, and lock water equivalent to 450 times the weight of the cell itself. At this point, it is the most amazing and effective way to lock water among...

Problems solved by technology

However, chitosan flocculants also have their limitations. For example, chitosan flocculants should be applied under acidic conditions, and the clarification range and clarification conditions of different traditional Chinese medicine extracts are different, and they have certain specificity.

[0007] In summary, in view of the complex composition and poor stability of the existing plant crude extract, and the existing purification methods have their limitations, it is necessary to find a method to effectively purify the plant crude extract and improve its stability
