Embodiment 1
[0039] An anti-allergic repair composition, prepared by the following method:
[0040] (1) Weigh the following dry raw materials in parts by weight: 30 parts of Kochia scoparia, 30 parts of chamomile, 10 parts of salvia miltiorrhiza, 30 parts of purslane, 0.1 part of kava pepper; mix, pulverize, and pass through a 40-mesh sieve;
[0041](2) Soak the dry material to be extracted with 85% (V / V) ethanol aqueous solution at room temperature until it is completely imbibition, the ratio of solid to liquid is 1:4; transfer it into a chromatography column, pack it, and compact it; then use 3 times column volume of 85% (V / V) ethanol aqueous solution for elution, the elution flow rate is 1 BV / H;
[0042] (3) Collect the eluent, rotatively evaporate, remove ethanol, and obtain a concentrated solution; add butanediol 3 times the weight of the concentrated solution and 1,2-hexanediol 0.01 times the weight of the concentrated solution; stir evenly, at 5°C Keep it warm for 10 hours, and the...
Embodiment 2
[0044] An anti-allergic repair composition, prepared by the following method:
[0045] (1) Weigh the following dry raw materials in parts by weight: 40 parts of Kochia scoparia, 20 parts of chamomile, 20 parts of salvia miltiorrhiza, 20 parts of purslane, 1 part of kava pepper; mix, crush, and pass through a 40-mesh sieve;
[0046] (2) Soak the dry material to be extracted with 85% (V / V) ethanol aqueous solution at room temperature until it is completely imbibed, and the ratio of solid to liquid is 1:3; transfer it to a chromatography column, pack it, and compact it; then use 3 times column volume of 85% (V / V) ethanol aqueous solution for elution, the elution flow rate is 2 BV / H;
[0047] (3) Collect the eluent, rotatively evaporate, remove ethanol, and obtain a concentrated solution; add butanediol 1 times the weight of the concentrated solution and 1,2-hexanediol 0.05 times the weight of the concentrated solution; stir evenly, at 3°C Keep it warm for 20 hours, and then filt...
Embodiment 3
[0049] An anti-allergic repair composition, prepared by the following method:
[0050] (1) Weigh the following dry raw materials in parts by weight: 35 parts of Kochia scoparia, 25 parts of chamomile, 15 parts of salvia miltiorrhiza, 24 parts of purslane, 0.5 part of kava pepper; mix, pulverize, and pass through a 40-mesh sieve;
[0051] (2) Soak the dry material to be extracted with 85% (V / V) ethanol aqueous solution at room temperature until it is completely imbibed, and the ratio of solid to liquid is 1:3.5; transfer it to a chromatography column, pack it, and compact it; 3 times column volume of 85% (V / V) ethanol aqueous solution for elution, the elution flow rate is 1.5 BV / H;
[0052] (3) Collect the eluate, rotatively evaporate, remove ethanol, and obtain a concentrated solution; add butanediol twice the weight of the concentrated solution and 1,2-hexanediol 0.04 times the weight of the concentrated solution; stir evenly, at 4°C Keep it warm for 15 hours, then filter it...
