Embodiment 1
[0037] A kind of extract microcapsules of Herba japonica, the preparation method of which comprises the following steps in sequence:
[0038] (1) Cut the stems of C. chinensis into sections, pass through a 60-mesh sieve, and dry by heat pump at 65°C and 1m / s wind speed for 0.5min. Take 20g of C. chinensis, soak in 800ml boiling water for 3 times, each time for 1h, and filter And combine the supernatant, then concentrate to 15% of the original volume, freeze-dry, then add 75vt% ethanol solution to thaw, then use ethanol solution (50vt%, 70vt%) as mobile phase, carry out macroporous resin purification, collect respectively After the solution was concentrated, it was separated by a SephadexL H-20 Sephadex column, and the mobile phase was ethyl acetate-ethanol solution (1:1, 1:2, v / v), and then the extract was evaporated and concentrated, and then freeze-dried. Freeze-dried powder of Decha Huangcao extract;
[0039] (2) Add the wall material (0.27g gelatin powder, 0.03g RG I pectin...
Embodiment 2
[0042] A kind of extract microcapsules of Herba japonica, the preparation method of which comprises the following steps in sequence:
[0043] (1) Cut the whole grass of C. chinensis into sections, pass through a 60-mesh sieve, and dry it with a heat pump at 65°C and a wind speed of 1m / s for 0.5min. Take 20g of C. chinensis, soak it in 800ml boiling water for 3 times, 1 hour each time, filter and dry Combine the supernatants, then concentrate to 15% of the original volume, freeze-dry, then add 75vt% ethanol solution to thaw, then use ethanol solution (50vt%, 70vt%) as mobile phase, carry out macroporous resin purification, collect liquid respectively After concentration, it was separated by SephadexL H-20 dextran gel column, the mobile phase was ethyl acetate-ethanol solution (1:1, 1:2, v / v), and then the extract was evaporated and concentrated, and then freeze-dried to obtain Freeze-dried powder of Herba Grass Extract;
[0044] (2) Add the wall material (0.27g gelatin powder,...
Embodiment 3
[0047] A kind of extract microcapsules of Herba japonica, the preparation method of which comprises the following steps in sequence:
[0048] (1) Heat-pump dry the leaves of C. chinensis at 65°C and 1m / s wind speed for 0.5min. Take 20g of C. chinensis, soak in 800ml of boiling water for 3 times, 1 hour each time, filter and combine the supernatant, and then concentrate to 15% of the original volume, freeze-dried, then added 75vt% ethanol solution to thaw, then used ethanol solution (50vt%, 70vt%) as the mobile phase, and carried out macroporous resin purification, respectively concentrated the collected liquids and passed through SephadexL H-20 Sephadex column separation, the mobile phase is ethyl acetate-ethanol solution (1:1,1:2, v / v), then the extract is evaporated and concentrated, and then freeze-dried to obtain the lyophilized extract of C. pink;
[0049] (2) Add wall material (0.245g gelatin powder, 0.027gRG I pectin okra polysaccharide powder, 0.03g high methoxyl pect...
