The invention relates to an allium macrostemon medicinal material extract, an extraction method, a preparation method and application, and systematically and deeply researches chemical components of an allium macrostemon medicinal material. Solves the problems that no literature report on the systematic research of the medium-polarity chemical components in the allium macrostemon medicinal material exists at home and abroad, and no report related to the preparation method and the application of two monomer compounds with novel structures separated from the allium macrostemon medicinal material is found. |
