TABLE 4 percent hygroscopicity of dry extract powders
As can be seen from table 4 and fig. 2, the moisture absorption rate of the dry extract powder was >15% after the dry extract powder was left to stand for 12 hours in a desiccator containing a saturated NaCl solution, which suggests that the dry extract powder has a strong moisture absorption property, and it is considered that the moisture absorption property was lowered by adding an auxiliary material.
2.2 investigation of the parameters of the pelletization Process
2.2.1 selection of auxiliary Material types
15 parts of dry extract powder are taken and divided into 5 groups, the 5 groups of dry extract powder are respectively mixed with excipient auxiliary materials of different types, the excipient auxiliary materials account for 10 percent of the dry extract powder, 95 percent of ethanol is sprayed, a 20-mesh screen is used for granulating, the temperature of an oven is 60 ℃, the drying is carried out for 1 hour, a 10-mesh screen is used for finishing the granules, and each index of the granules is inspected, wherein the granule moisture absorption percentage test method is the same as the step of the moisture absorption test of the dry extract powder of 2.1.2. The test results are shown in Table 5.
The standard of the qualified particles is as follows: can pass through a 10 mesh screen and cannot pass through an 80 mesh screen.
TABLE 5 selection of adjuvant classes
As is clear from Table 5, the soft material state obtained from dextrin, mannitol and microcrystalline cellulose is preferable. Mannitol and microcrystalline cellulose are easy to granulate. Compared with the hygroscopicity and the granule yield, the microcrystalline cellulose has more ideal granulating effect, so the microcrystalline cellulose is selected as an auxiliary material for granulating in the experiment.
2.2.2 adjuvant usage and wetting agent concentration test
According to the dosage requirement of the prescription, 1.2g of dry extract powder, 1.5g of fructus cannabis powder and 1.5g of semen pruni powder are taken daily (hereinafter, the three powder mixtures are collectively called as "drug powder"). The pre-experiment shows that the dosage of each capsule shell of the No. 0 capsule is 0.5g, calculated by taking 12 capsules per day, and the dosage of all auxiliary materials except the medicine powder is 1.8g, wherein about 20 percent of pectin, namely about 1.2g, is needed to be added before the capsules are filled after the granulation is completed. Therefore, the daily amount of other auxiliary materials is at most 0.6g.
In order to examine the dosage of microcrystalline cellulose as an auxiliary material, a proper amount of medicine powder and microcrystalline cellulose are mixed according to the proportion of 10:1, 8.5:1 and 7:1, 3 parts of each group are respectively sprayed with ethanol with the concentration of 85%, 90% and 95%, and the mixture is sieved by a 20-mesh sieve for granulation, and the dosage of the auxiliary material and the concentration of a wetting agent are examined. The results are shown in Table 6.
