Abstract

The invention relates to a method for extracting anoectochilus roxburghii and application of extracts of the anoectochilus roxburghii. The method includes steps of S1, drying and grinding anoectochilus roxburghii materials and feeding the anoectochilus roxburghii materials through sieves with the sizes of 10-20 meshes to obtain anoectochilus roxburghii powder; S2, carrying out explosion treatment on the anoectochilus roxburghii powder for 3min-30min by the aid of water vapor under the pressure of 0.5MPa-2MPa, allowing the anoectochilus roxburghii powder to be extracted by the aid of existing technologies in follow-up procedures after the anoectochilus roxburghii powder is subjected to explosion treatment, or allowing the anoectochilus roxburghii powder to be selectively extracted by the aid of sub-critical water and/or sub-critical alcohol. The water vapor is used as an explosion medium. The method and the application have the advantages that effective components such as polysaccharides, total flavonoids and total alkaloids in the anoectochilus roxburghii can be sufficiently enriched by the aid of the method, accordingly, the method is high in medicinal material resource utilization rate, the extraction rates of the effective components can be greatly increased, the extraction efficiency can be obviously improved, the batch processing capacity can be greatly improved, the processing speeds can be greatly increased, and the method is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of processing and application of Chinese herbal medicines, and more specifically, relates to an extraction method of Aurantia clematis and the application of the extract. Background technique [0002] Anoectochilus roxburghii, also known as Anoectochilus roxburghii, has a sweet and slightly bitter taste, flat nature, and slight coldness.
