[0026] The invention provides a preparation method of psoraleae-free decoction preparation, which is carried out according to the following steps:
[0027] 1) Wash the psoraleae medicinal material to remove impurities, and dry it below 60°C;
[0028] 2) Take the dried psoralen medicinal material and coarsely pulverize it, pass through a 20-40 mesh sieve to obtain a coarse powder;
[0029] 3) Add water 8-10 times the weight of the coarse powder to the coarse powder obtained in step 2), soak for 60-90 minutes at a water temperature of 35-40°C, then ultrasonically treat and filter to obtain the initial extract and filter residue Ⅰ , refrigerate the initial extract, and transfer the filter residue to step 4);
[0030] 4) Add ethanol with a volume ratio of 50~70% to the filter residue Ⅰ, control the weight / volume ratio of filter residue Ⅰ and ethanol to 1:7~1:10mg / mL, and extract at 35~40°C for 1.5~2 hours , filter to obtain the filtrate and filter residue II, dry the filter resi...
Embodiment 1
[0040] The invention provides a preparation method of psoraleae-free decoction preparation, which is carried out according to the following steps:
[0041] 1) Wash the psoraleae medicinal material to remove impurities, dry at 60°C, and control the water content to ≤3.0wt%;
[0042] 2) taking the dried psoralen medicinal material and coarsely pulverizing it, passing through a 30-mesh sieve to obtain a coarse powder;
[0043] 3) Add water 9 times the weight of the coarse powder to the coarse powder obtained in step 2), soak for 75 minutes at a water temperature of 37°C, and then ultrasonically treat it with a processing frequency of 25kHz, power of 400W, time of 12min, and repeat times of 3 times , filter to obtain the initial extract and filter residue I, refrigerate the initial extract, and transfer the filter residue to step 4);
[0044] 4) Add ethanol with a volume ratio of 55% to filter residue I, control the weight / volume ratio of filter residue I to ethanol to 1:8mg / mL, ...
Embodiment 2
[0047] The invention provides a preparation method of psoraleae-free decoction preparation, which is carried out according to the following steps:
[0048] 1) Wash the psoraleae medicinal material to remove impurities, vacuum-dry at 50°C, and control the water content to ≤3.0wt%;
[0049] 2) Take the dried psoralen medicinal material and coarsely pulverize it, pass through a 20-mesh sieve to obtain a coarse powder;
[0050] 3) Add water 8 times the weight of the coarse powder to the coarse powder obtained in step 2), soak for 90 minutes at a water temperature of 40°C, and then ultrasonically treat it with a processing frequency of 30kHz, power of 300W, time of 20min, and the number of repetitions is 3 times , filter to obtain the initial extract and filter residue I, refrigerate the initial extract, and transfer the filter residue to step 4);
[0051] 4) Add ethanol with a volume ratio of 70% to filter residue I, control the weight / volume ratio of filter residue I to ethanol ...
