The invention belongs to the technical field of extraction of Chinese herbal medicine, and particularly relates to a herba centellae extract with anti-inflammation and anti-sensitivity effects. The herba centellae extract is prepared by adopting the following preparation method: S1. adding ethanol into herba centellae powder for extraction, carrying out ultrasonic assisted extraction, then centrifuging or filtering, and collecting a filtrate; S2. adding activated carbon to the filtrate obtained in step 1 for decoloring, centrifuging, and collecting a decolored filtrate; S3. concentrating the decolored filtrated obtained in step 2, adding a chitosan liquid for decontamination, filtering, and collecting a decontaminated filtrate; S4. adding macroporous adsorption resin to the decontaminated filtrate for purification, and eluting with ethanol to obtain an eluent; S5. concentrating, desalting and drying the eluent obtained in step 4 to obtain the herba centellae extract, wherein in S1, the concentration of ethanol is 60-90%, the ultrasonic power is 228W-380W, and the material-to-liquid ratio is 1:20-80. The herba centellae extract provided by the invention has remarkable anti-inflammation and anti-sensitivity effects, is prominent in oxidation resistant and free radical removal effects, and can be widely applied to skin care products with anti-inflammation and anti-sensitivity effects.

The preparation of 1,2-diacyl-3-(6-deoxy-6-sulfo- alpha-D-glucopyranosyl)-sn-glycerin ester includes the steps of leaching crushed sea algae with organic solvent, adding water solution of potassium chloride into filtrate to delaminate and depression evaporating organic phase to obtain general algae ester, mounting diethyl amino ethyl cellulose through serial treatment in column; dissolving general algae ester in mixed solvent of chloroform and methanol, depurating in the column with the mixed chloroform and methanol solvent and eluted with mixed solvent of CHCl3, CH3OH and NH3.H2O to obtain coarse product; and purifying with mixed of CHCl3, CH3OH and KCl solution and evaporation to eliminate organic phase; and dissolving the product in methanol, eluting with acetone in activated silica gel column and evaporating to obtain purified product.

The invention discloses application of eucommia ulmoides extracts in the preparation of compositions for tranquilizing and inducing sleep and application of the eucommia ulmoides extracts in the preparation of compositions for treating insomnia, anxiety neurosis or convulsion. The eucommia ulmoides extracts are continuously extracted from eucommia bark, eucommia leaves, eucommia male flowers and\or eucommia whole plants by petroleum ether, ethyl acetate, normal butanol, ethanol and water. The eucommia ulmoides extracts are obtained by extracting from eucommia plants. And results of researcheson the application of the eucommia ulmoides extracts in the field of tranquilization and sleep induction show that the eucommia ulmoides extracts have remarkable effects of tranquilizing and inducingsleep and resisting convulsion, wherein the ethyl acetate extract of eucommia and the normal butanol extract of the eucommia have more obvious effects. The eucommia ulmoides extracts are natural active materials for researching and developing novel health-care foods and new drugs for tranquilizing and inducing sleep, and can be applied to the treatment of nervous system diseases such as insomnia,anxiety neurosis and convulsion without side effects and psychic dependence.

The invention discloses applications of an eucommia ulmoide total alkaloid for preparing a combination with a sedative-hypnotic effect, and also discloses applications of the eucommia ulmoide total alkaloid for preparing the combination used for treatment of insomnia, anxiety or convulsion; the eucommia ulmoide total alkaloid is prepared by extracting, separating and purifying an eucommia ulmoidespark, an eucommia ulmoide leaf, an eucommia ulmoide male flower and / or eucommia ulmoide whole-plant. The invention extracts, separates and purifies the plant eucommia ulmoide. The invention obtains the eucommia ulmoide total alkaloid by extracting, separating and purifying plant eucommia ulmoide and carries out the application research of the eucommia ulmoide total alkaloid in the sedative-hypnotic field; the result indicates that the eucommia ulmoide total alkaloid has obvious sedative-hypnotic effect and anti-convulsion effect, is a natural active matter for researching and developing a novel health-caring food and new drugs with the sedative-hypnotic effect, can be used for curing the nervous system diseases such as insomnia, anxiety or convulsion and has no side effects or spiritual dependency.
