Embodiment 1
[0030] Embodiment 1, investigate the influence of different steam distillation conditions on the active ingredient
[0031] The composition of the prescription is as follows:
[0032] Danshen 300.0g, Galangal 300.0g, Myrobalan 180.0g, Hanshuishi 200.0g, Amomum 200.0g,
[0033] 200.0g Cyperus cyperi, 120.0g sandalwood, 100.0g wulingzhi.
[0034] The preparation method is as follows:
[0035] 1) Carry out the following treatment to the Chinese herbal medicines: grind the hanshuishi, sandalwood, and wulingzhi into fine powders respectively for later use; Cut Cyperus Cyperi and Galangal into pieces for later use;
[0036] 2) extracting 70% ethanol aqueous solution (adding 6 times volume of ethanol for 4 hours for the first time and adding 4 times the volume of ethanol extraction for 3 hours, the third time plus 4 times the volume of ethanol extraction for 2 hours), combine the extracts, concentrate to a thick paste with a relative density of 1.30-1.35 (50°C), spray dry (inlet ...
Embodiment 2
[0044] Embodiment 2, investigate the impact of different spray drying conditions on the active ingredient
[0045] The composition of the prescription is the same as in Example 1.
[0046] The preparation method is as follows:
[0047] 1) Carry out the following treatment to the Chinese herbal medicines: grind the hanshuishi, sandalwood, and wulingzhi into fine powders respectively for later use; Cut Cyperus Cyperi and Galangal into pieces for later use;
[0048] 2) extracting 70% ethanol aqueous solution (adding 6 times volume of ethanol for 4 hours for the first time and adding 4 times the volume of ethanol extraction for 3 hours, and the third time adding 4 times the volume of ethanol extraction for 2 hours), combined the extracts, concentrated to a thick paste with a relative density of 1.30-1.35 (50°C), and spray-dried to obtain the medicinal powder 1;
[0049] 3) Extract volatile oil from the amomum and sandalwood medicinal materials treated in step 1) by distillation...
Embodiment 3
[0056] Example 3, comparative spray drying method and microwave vacuum drying method on the active ingredient content in Jingzhuweitai capsule alcohol extract thick paste
[0057] Table 3 shows the contents of tanshinone ⅡA and galangin in Jingzhuweitai capsule alcohol extract thick paste after drying by the above method. This result shows that the spray drying method is superior to the microwave vacuum drying method. The relative density of the alcohol extract thick paste is 1.30 (50°C). Other technological conditions of the spray drying method are: air inlet temperature 130°C, air outlet temperature 70°C, air inlet pressure 16.5kPa; other technological conditions of the microwave vacuum drying method are: medium and low firepower, intermittent heating for the first 15 minutes (open 1 minute off for 1 minute), and then continue to heat, control the temperature at 24°C-39°C, and vacuum degree -0.084MPa.
