The invention belongs to the technical field of separation and extraction of natural compounds, and discloses an extraction method and application of quaternary keto acid compounds. The extraction method comprises the following steps: (1) Hypomontagnella monticulosa YX702 is placed in a culture medium for cultivation, then soaked in an organic solvent, filtered, and the filtrate is taken to obtain a crude extract, which is for subsequent use. The preservation number of Hypomontagnella monticulosa YX702 is CGMCC No. 40063; (2) extract the crude extract obtained in step (1), take the extract phase, and dry to obtain an extract; (3) separate and purify the extract obtained in step (2). The extraction method has high extraction efficiency, and the extraction method has broad application prospects in the preparation of medicines. |
