Embodiment 1
[0088] The preparation process selection of embodiment 1 Daochi powder formula granules
[0089] Preparation:
[0090] Take raw rehmannia glutinosa, akebia, bamboo leaves, and raw licorice with a mass ratio of 1:1:1:1, soak them in water, decoct them, filter them, combine the filtrates, concentrate them into a clear paste, and then dry and granulate them.
[0091] 1. The research on the extraction process of Daochi powder formula granules is as follows:
[0092] Influencing factors are: extraction times, extraction time, water addition (unit is L / Kg total amount of medicinal materials). Orthogonal test is used to optimize the extraction process, choose L 9 (3 4 ) orthogonal table, focusing on the above three factors, taking the content of glycyrrhizic acid as the investigation index, and the factor level table is shown in Table 2.

[0094]
[0095] Test method: Weigh 100g of raw rehmannia root, 100g of raw licorice, 100g of akebia, and 100g of bamboo...
Embodiment 2
[0106] The preparation of embodiment 2 Daochi powder formula granules
[0107] Take 180.1g rehmannia glutinosa, 180.0g akebia, 180.0g bamboo leaves, and 180.2g licorice, soak in water for 30 minutes, decoct twice, add 10 times the amount of water for the first time, add 8 times the amount of water for the second time, and decoct each time Boil for 1.0 hour, filter, combine the two filtrates, concentrate under reduced pressure at 80°C, concentrate to a clear paste with a relative density of 1.05-1.10 (60°C), microwave dry, the microwave power is 5Kw, the material temperature is 65°C, and the drying time is After 25 minutes, it was dried to obtain extract powder, and the finished product was obtained through granulation, sub-packaging, sieving, and testing. Process flow chart see figure 1 .
[0108] The results of dry extract powder are shown in Table 6.
[0109] Table 6 Extract result table
[0110]
[0111] 192.8g of Daochisan formula granule powder was obtained.
