specific Embodiment 1
[0038] Preparation: Take fresh pig gall, wash it, dry it in the oven at 70°C for 12 hours (the time depends on the moisture content of the sample, it can be 12-24 hours), take it out and put it in a drying box to cool, and crush it with a grinder to 80 mesh Sieve, and store the powder in a brown jar.
[0039] Extraction: Add water to the powdered gall gall, heat it to 60°C-70°C in a water bath, extract for 2 hours, stir once every 10 minutes, filter with gauze, add water to the residue, continue to extract for 2 hours at 60°C-70°C , Stir once every 10min, filter through gauze, and combine the extracts.
[0040] Suction filtration: first use gauze to coarsely filter to remove large particles and precipitate, so as to increase the speed of suction filtration. Install suction filtration equipment, add a small amount of extract solution into the Buchner funnel for suction filtration, because pig gall contains gelatinous sediment, the filter paper is easy to cause blockage, result...
