The present invention provides a high-content carotenoid compound from Adonis amurensis. The content of the total carotenoid of the carotenoid compound is higher than 95%. The content of all-trans (3S, 3′S)-carotenoid is higher than 80%. The carotenoid crystals have a high purity, and can be used in multiple forms in the fields of a dietary supplement of a human being, a food additive, a feed additive and a cosmetic product. In addition, the present invention also provides a method for manufacturing the compound.

The present invention belongs to the technical field of plant cultivation, and particularly relates to a cultivation method for Adonis amurensis. By removing leaves and disinfecting the Adonis amurensis seedlings with the original soil, the soil environment around the roots of Adonis amurensis is ensured. Meanwhile, combined with appropriate irrigation, shading and stubble removal on the leaf surface, the survival rate of Adonis amurensis can be improved, the flowering period can be prolonged, and its ability to adapt to the soil and the external environment can be enhanced, providing a technical basis for the popularization and application of Adonis amurensis.

The present invention provides alternative splicing polypeptides and their applications. The alternative splicing polypeptide of the present invention is a polypeptide composed of 23 amino acids at the N-terminus of HBFD from Adonis amurensis, which can achieve specific splicing in tobacco and realize the tandem expression of multiple proteins in a single expression cassette. The alternative splicing polypeptide of the present invention has better splicing specificity in plants than the 2A self-cleaving polypeptide of picornavirus reported by predecessors, which is beneficial to reducing the occurrence of non-specific splicing. The alternative splicing polypeptide of the present invention is a protein splicing element derived from plants, which is beneficial to improving the application value of the tandem expression technology of multiple proteins based on a single expression cassette in plant bioreactors.
