Embodiment 1
[0023] Example 1. Preparation of rosemary total diterpene phenols
[0024] The harvested rosemary is sun-dried and cut into sections. Add 10 times the amount of crude drug and 70% (v / v) ethanol for reflux extraction for 3 times; cool the combined extracts to 40°C, and filter to remove insolubles , To obtain a greenish-brown filtrate; decolorization: add 0.1% (g / ml) activated carbon of the filtrate volume weight percentage to this filtrate, decolorize at 55°C for 20 minutes, filter and remove the activated carbon to obtain a clear and transparent red-brown liquid medicine; The filtrate was concentrated to a drug solution with a relative density of 1.10, added 2 times the crude drug amount of water, stirred, filtered, and the water-soluble impurities were dissolved in the filtrate to be removed. The filter residue was dried and crushed to obtain the rosemary total diterpene of the present invention Phenol is a light yellow powder with a total phenol content of 80%. Such as figure 2 ...
Embodiment 2
[0025] Example 2. Preparation of rosemary total diterpene phenols
[0026] The harvested rosemary herbs were sun-dried and cut into sections, and 5 times the amount of crude drug was added to 90% (v / v) methanol percolation to extract once; the combined extracts were allowed to cool to 60°C and filtered to remove insoluble To obtain a green-brown filtrate; decolorization: add 0.05% (g / ml) activated carbon of the filtrate volume weight percentage to this filtrate, decolor at 30°C for 40 minutes, filter and remove the activated carbon to obtain a clear and transparent red-brown liquid medicine; Concentrate the filtrate to a drug solution with a relative density of 1.00, add 0.4 times the crude drug amount of water, stir, filter, and dissolve the water-soluble impurities in the filtrate to be removed. The filter residue is dried and pulverized to obtain a light yellow powder, which is the product of the present invention. The total diterpene phenols of rosemary are light yellow powder...
Embodiment 3
[0027] Example 3. Preparation of rosemary total diterpene phenols
[0028] The harvested rosemary medicinal materials were dried and cut into sections, added with 12 times the amount of the crude drug, 50% (v / v) acetone soaked and extracted 5 times; the combined extracts were allowed to cool to 20°C, and the insoluble matter was removed by filtration , To obtain a greenish-brown filtrate; decolorization: add 0.5% (g / ml) activated carbon of the filtrate volume weight percentage to this filtrate, decolorize at 80°C for 5 min, filter and remove the activated carbon to obtain a clear and transparent red-brown liquid medicine; The filtrate is concentrated to a drug solution with a relative density of 1.05, 4 times the crude drug amount of water is added, stirred, filtered, and the water-soluble impurities are dissolved in the filtrate to be removed. The filter residue is dried and pulverized to obtain a light yellow powder, which is the mystery of the present invention. The total diter...
