Embodiment 1

[0016] Example 1 Plant composition (I) and preparation method

[0017] Weigh 4kg of Glycyrrhizae glabra, 3kg of Rhizoma Chuanxiong, 1.5kg of seabuckthorn, and 1.5kg of Chrysanthemum chrysanthemum according to the proportion, crush the above-mentioned plant composition, sieve, add an ethanol extraction solvent with a volume fraction of 70% according to the liquid-to-material mass ratio of 15:1 After soaking for 2 hours, extract at room temperature with a high-pressure homogeneous extractor under the pressure of 40MPa. After the extract is centrifuged, the membrane is concentrated and then adsorbed with AB-8 macroporous resin. The volume fraction is 70%, 90% respectively Ethanol was eluted twice, the eluate was collected, the membrane was concentrated to 5 kg of extract, and then 5 kg of butanediol was added to dissolve and filtered to obtain 10 kg of plant composition.

Embodiment 2

[0018] Example 2 Plant composition (II) and its preparation method

[0019] Weigh 3.5kg of Glycyrrhizae glabra, 2.5kg of Rhizoma Chuanxiong, 2.5kg of Hippophae rhamnoides, and 1.5kg of Chrysanthemum chrysanthemum according to the ratio, crush the above-mentioned plant composition, sieve, add ethanol with a volume fraction of 60% according to the mass ratio of liquid to material of 15:1 Extract the solvent, after soaking for 2 hours, extract at room temperature with a high-pressure homogeneous extractor under 50MPa pressure, extract the liquid after centrifugation, concentrate with membrane, and then adsorb with AB-8 macroporous resin, with volume fractions of 75%, 90% % ethanol was eluted twice, the eluate was collected, the membrane was concentrated to 5 kg of extract, and then 5 kg of butanediol was added to dissolve and filtered to obtain 10 kg of plant composition.

Embodiment 3

[0020] Example 3 Plant composition (Ⅲ) and its preparation method

[0021] Weigh 3kg of Glycyrrhizae glabra, 2.5kg of Rhizoma Chuanxiong, 2.5kg of Hippophae rhamnoides, and 2kg of Chrysanthemum chrysanthemum according to the proportion, pulverize the above-mentioned plant composition, sieve, add an ethanol extraction solvent with a volume fraction of 75% according to the liquid-material mass ratio of 15:1 After soaking for 2 hours, extract at room temperature with a high-pressure homogeneous extractor under the pressure of 50MPa. After the extract is centrifuged, the membrane is concentrated and then adsorbed with AB-8 macroporous resin. The volume fractions are 50%, 70%, and 90% ethanol was eluted three times, the eluate was collected, the membrane was concentrated to 5 kg of extract, and then 5 kg of butanediol was added to dissolve and filtered to obtain 10 kg of plant composition.

Abstract

The invention discloses a plant composition with the efficacy of whitening the skin. The plant composition is characterized by being prepared from the following raw materials in percentage by weight: 15-50 % of rhizoma glycyrrhiza glabra, 10-40 % of rhizoma ligustici wallichii, 5-35 % of fructus hippophae, and 5-35 % of chrysanthemum morifolium flowers. A preparation method of the plant composition comprises the following steps: smashing the plant composition, carrying out screening, carrying out soaking by adopting an extracting solvent, carrying out room-temperature extracting by adopting a high-pressure homogenizing extractor, carrying out centrifugal separation on the extracted solution, carrying out membrane concentration, carrying out adsorbing by adopting macroporous resin, carrying out eluting for a plurality of times by adopting ethanol solution, collecting the eluate, after membrane concentration, adding with butanediol with the weight being equal to that of the extracted concentrated solution for dissolving, and carrying out filtering, thus obtaining the plant composition. The plant composition obtained by the method has the effects of efficiently inhibiting melanogenesis, scavenging free radicals and screening the sunlight, and has the effect of whitening and brightening the skin after being applied to the cosmetics. The plant composition has the advantages that the raw materials are easily available, the preparation method is simple and convenient, as well as pollution-free and safe, and the application prospect and market prospect are very good.

Description

technical field [0001] The invention relates to a plant composition, specifically a plant composition with whitening effect and its application in cosmetics, belonging to the field of cosmetics. Background technique [0002] Since ancient times, whiteness has been regarded as beauty in China. As the saying goes, "one white covers all ugliness", fair skin is the lifelong pursuit of all women. In addition to natural dark skin, from the perspective of traditional Chinese medicine, not white is often a manifestation of poor health, imbalance of viscera and blood, and a sub-healthy state, often showing symptoms such as chloasma and freckles on the face. For the treatment of facial spots, there are methods such as laser or intense pulsed light therapy, external drug therapy, etc.; wherein laser or intense pulsed light therapy is very harmful to the skin and is not commonly used; cosmetic whitening is the most commonly used method at present. [0003] There are major defects in th...
