(EP3072883) 1. A high-content carotenoid compound from flower, stem and fruit of adonis amurensis, characterized in that, the content of the total carotenoid in the high-content carotenoid compound is higher than 95wt%, wherein the proportion of all-trans (3S, 3'S)-astaxanthin in the total carotenoid is higher than 80wt%, the all-trans (3S, 3'S) - astaxanthin has the molecular structure as shown in formula (I): 2. The high-content carotenoid compound according to claim 1, characterized in that, the total carotenoid comprises semi-astacene, astacene and adonirubin. 3. The high-content of carotenoid compound according to claim 2, characterized in that, the proportion of the total content of semi-astancene and astacene in the total carotenoid is less than 10 wt %, the proportion of adonirubin in the total carotenoid is less than 10 wt %. 4. A method of preparing a high-content carotenoid compound by using adonis amurensis extract as raw material, characterized in that, comprising the following steps:  (a) mixing Adonis amurensis extract with alcohols solvent and fully dissolving, to obatain a mixed solution;  (b) heating the mixed solution of the step (a) to 25∼75°C, and dropwise adding an alkali solution to the reaction, and the reaction time is 0.5 ∼ 6.0hr;  (c) adding a mixture of alcohols solvent and water to obtain a reaction solution, after completion of the step (b) ;  (d) filtering the reaction solution of the step (c) to obtain a filter cake, and then washing the filter cake with a mixture of alcohols solvent and water; and  (e) drying the filter cake of the step (d) in vacuum to obtain a carotenoid compound;wherein, in the high-content carotenoid compound, the content of the total carotenoid is higher than 95 wt %, the propotion of the all-trans (3S, 3'S) astaxanthin in the carotenoid is higher than 80wt%, the all-trans (3S, 3'S) - astaxanthin has the molecular structure as shown in formula (I): 5. The method according to claim 4, characterized in that, in the step (a), the ratio of the volume of the alcohols solvent to the weight of Adonis amurensis extract is 5∼50 times, preferably, the ratio of the volume of the alcohols solvent to the weight of Adonis amurensis extract is 25 ∼ 40 times. 6. The method according to claim 4, characterized in that, in the step (b), the concentration of the alkali solution of the reaction is 0.01-2.50 mol/L after adding dropwise the alkali solution, preferably is 1.00 ∼ 2.00 mol/L. 7. The method according to claim 5 or 6, characterized in that, the alcohols solvent in the step (a) is ethanol, propylene glycol or glycerol; the alkali solution in step (b) is sodium hydroxide solution, potassium hydroxide solution or sodium methoxide solution. 8. The method according to claim 4, characterized in that, the volume ratio of the alcohols solvent to water in the step (c) is 1:5 ∼ 10; the volume ratio of the alcohols solvent to water in the step (d) is 2 ∼ 3:1. 9. A composition comprising the high-content carotenoid compound according to any one of claim 1 ∼ 3. 10. The composition according to claim 9, characterized in that, further comprising one or more of vegetable oil, modified starch, sucrose, dextrin and gelatin.
