Embodiment 1
[0041] Take 200kg of Duhuo decoction pieces, add water to decoct twice, decoct with 10 times the weight of Duhuo decoction pieces in water for 2 hours, add 8 times the weight of Duhuo decoction pieces in the second decoction and decoct for 2 hours, combine the two decoctions, and concentrate in vacuum to Extraction with a relative density of 1.0-1.1 (80°C), spray drying (inlet air temperature 185°C-200°C, outlet air temperature 90°C-110°C; extract preheating temperature 50°C-60°C; material pump speed 450 -700 rev / min), to get lovage spray-dried powder, add 0-5% dextrin (calculated based on the weight of lovage spray-dried powder), dry granulate, get lovage granules with a particle size of 18-40 mesh. Each gram of lovuo granules contains 5g of crude drug equivalent to lovuo decoction pieces.
[0042] After preparation, the Duhuo granules were qualitatively identified by thin-layer chromatography, and the specific methods were as follows:
[0043] Take 1g of this product, grind...
Embodiment 2
[0047] Embodiment 2: the preparation method of lovage granules:
[0048] Take 200kg of Duhuo decoction pieces, add water to decoct twice, decoct with 8 times the weight of Duhuo decoction pieces in water for 1 hour, add 6 times the weight of Duhuo decoction pieces in the second decoction and decoct for 1 hour, combine the two decoctions, and concentrate in vacuum to Extraction with a relative density of 1.0-1.1 (80°C), spray drying (inlet air temperature 185°C-200°C, outlet air temperature 90°C-110°C; extract preheating temperature 50°C-60°C; material pump speed 450 -700 rev / min), to obtain lovage spray-dried powder, add 5-15% dextrin (calculated by the weight of lovage spray-dried powder), and dry granulate to obtain lovage granules with a particle size of 18-40 mesh. Each gram of lovuo granules contains 4g of crude drug equivalent to lovuo decoction pieces.
[0049] After preparation, the Duhuo granules were qualitatively identified by thin-layer chromatography, and the spe...
Embodiment 3
[0054] Embodiment 3: the preparation method of lovage granules:
[0055] Take 200kg of Duhuo decoction pieces, add water to decoct twice, decoct with 8 times the weight of Duhuo decoction pieces in water for 1 hour, add 6 times the weight of Duhuo decoction pieces in the second decoction and decoct for 1 hour, combine the two decoctions, and concentrate in vacuum to Extraction with a relative density of 1.0-1.1 (80°C), spray drying (inlet air temperature 185°C-200°C, outlet air temperature 90°C-110°C; extract preheating temperature 50°C-60°C; material pump speed 450 -700 rev / min), to obtain lovage spray-dried powder, add 15-25% dextrin (calculated based on the weight of lovage spray-dried powder), and dry granulate to obtain lovage granules with a particle size of 18-40 mesh. Each gram of Duhuo granules contains 3.3g of crude drug equivalent to Duhuo decoction pieces.
