Embodiment 1
[0034] Example 1. The preparation process of the active parts of the phthalides in Ligusticum chuanxiong
[0035] After pulverizing 1 kg of Rhizoma Chuanxiong medicinal material to be extracted, add 10 L of aqueous ethanol solvent (ethanol concentration is 80%), soak at room temperature for 24 hours, extract twice at 45° C. for 1 hour each time, filter to remove medicinal residues, and combine twice A total of 20 L of the filtrate was collected under reduced pressure at 45°C until the solvent had no alcohol smell, and 3 L of the concentrated solution of Rhizoma Chuanxiong was obtained. Add 1L of water to the concentrated extract of Chuanxiong Rhizoma Rhizoma Chuanxiong, mix well to prepare the extract, then add 2L of petroleum ether saturated with water in advance, extract once at 25°C, let stand for 48 hours to separate the layers, and collect the organic The petroleum ether extract of Ligusticum chuanxiong was obtained, the remaining water phase was added to 2 L of ethyl ace...
Embodiment 2
[0036] Example 2. Preparation process of effective parts of Angelica phthalides
[0037] After crushing 1 kg of angelica medicinal materials to be extracted, add 10 L of aqueous ethanol solvent (ethanol concentration is 80%), soak at room temperature for 24 hours, extract twice at 45° C. for 1 hour each time, filter to remove medicinal residues, and combine twice A total of 20 L of the filtrate was collected under reduced pressure at 45°C until the solvent had no alcohol smell, and 3 L of the concentrated solution of Angelica sinensis was obtained. Add 1L of water to the concentrated solution of angelica extract, mix well to make the solution to be extracted, then add 2L of petroleum ether saturated with water in advance, extract once at 40°C, let stand for 48 hours to separate the layers, and collect the organic phase, add an appropriate amount of anhydrous sodium sulfate to remove water, and obtain angelica petroleum ether extract. Pack 200g of silica gel (100-200 mesh) int...
Embodiment 3
[0038] Example 3. The preparation process of the effective parts of the compound chuanxiong angelica phthalide components
[0039] Grinding 1 kg of Rhizoma Chuanxiong and Angelica sinensis to be extracted (the ratio of the two medicinal materials is 1:1), adding 10 L of aqueous ethanol solvent (75% ethanol concentration), soaking at room temperature for 24 hours, and extracting twice at 45 ° C, each After 1 hour, the medicinal residues were removed by filtration, and a total of 20 L of the two filtrates were combined, and the solvent was recovered under reduced pressure at 45°C until there was no alcohol smell, and 3.5 L of the compound medicinal material extraction concentrate was obtained. Add 1L of water to the concentrated extraction solution, mix well to prepare the extraction solution, then add 1.5L of n-hexane saturated with water in advance, extract 3 times at 40°C, let stand for 2 hours to separate the layers, and collect the organic phase Obtain n-hexane extract.
