Embodiment 1
[0034] Example 1: Isolation of Oxycyclopentadecane-2-one from Dictyophora
[0035] The implementation steps of this embodiment are as follows:
[0036] A. Pretreatment
[0037] Drying Dictyophora until the water content is 65108% based on the total weight of the dried Dictyophora, and then crushing it into 50406050 mesh to obtain a dry Dictyophora powder;
[0038] B. Extraction
[0039] Add the dry Dictyophora powder that step A obtains in the first round bottom flask, then add water, the weight ratio of described dry Dictyophora powder and water is 2:50;
[0040] Simultaneously, organic solvent is added in the second round bottom flask, and described organic solvent is ethanol organic solvent;
[0041] The volume ratio of the organic solvent to the water is 2:10;
[0042] Then, connect the above two round bottom flasks to the distillation extraction device at the same time, put the first round bottom flask into an oil bath to heat, and control its temperature at 138°C; pu...

[0060] Example 3: Isolation of Oxycyclopentadecane-2-one from Dictyophora
[0061] The implementation steps of this embodiment are as follows:
[0062] A. Pretreatment
[0063] Drying Dictyophora until the water content is 10% based on the total weight of the dried Dictyophora, and then crushing it into 60 meshes to obtain a dry Dictyophora powder;
[0064] B. Extraction
[0065] Add the dry Dictyophora powder that step A obtains in the first round bottom flask, then add water, the weight ratio of described dry Dictyophora powder and water is 3:60;
[0066] Simultaneously, organic solvent is added in the second round bottom flask, and described organic solvent is octanol organic solvent;
[0067] The volume ratio of the organic solvent to the water is 4:12;
[0068] Then, connect the above two round bottom flasks to the distillation extraction device at the same time, put the first round bottom flask into an oil bath to heat, and control its temperature at 140°C; put the s...
