[0035] Method for extracting epoxy compounds and anhydrides from figs:
[0036] Step 1. Take 13 kg of fig Branschweig fruit slices and freeze-dry them; at room temperature, cold-soak the dried freeze-dried fruit with 70% ethanol at a mass concentration 10-20 times its weight, ultrasonically assisted extraction and filtration, and After solid-liquid separation and air-drying of the solid residue, repeat the above-mentioned cold soaking 2-3 times; combine the filtered filtrates, place them overnight, filter out the lower layer of precipitation, and then evaporate and concentrate the supernatant; obtain 70% ethanol extract for later use;
[0037] Step 2. Add 10-20 times of water to the extract obtained in step 1 to dissolve until transparent, then store it in refrigerator at -4°C for 12 hours. , ethyl acetate for extraction; then concentrate under reduced pressure below 50°C to the corresponding extract, and set aside;
[0038] Step 3: take the petroleum ether extract from step ...

[0053] Method for extracting epoxy compounds and anhydrides from figs:
[0054] Step 1: Take 15kg of fig Zhongnonghong variety fruit slices, freeze-dry; freeze-dried fruit is cold-soaked with 70% ethanol at a mass concentration of 10-20 times its weight under room temperature, ultrasonically assisted extraction and filtration, through solid-liquid After separation, after the solid residue is air-dried, repeat the above-mentioned cold soaking 2-3 times; combine the filtered filtrates, place them overnight, filter out the lower layer of precipitation, and then evaporate and concentrate the supernatant; obtain 70% ethanol extract for later use;
[0055] Step 2. Add 10-20 times of water to the extract obtained in step 1 to dissolve until transparent, then store it in refrigerator at -4°C for 12 hours. , ethyl acetate for extraction; then concentrate under reduced pressure below 50°C to the corresponding extract, and set aside;
