Embodiment 1
[0012] The impact of different solvent extractions of embodiment 1 on active ingredient
[0013] Weigh 3 groups of Semen Cassiae and Folium Folium with a weight ratio of 1:1, use 70% ethanol, ethyl acetate and water as solvents respectively, and extract with reflux method, the amount of solvent is 7 times of the weight of medicinal materials, the extracted The number of times is 2 times, 1 hour each time; the extracts of each group are combined and recovered, and the solvent is recovered to make a dry paste, and the alcohol extraction group, ethyl acetate extraction group and water extraction group are prepared; the total solid yield of each group, Chrysophanol content and indirubin content are specifically shown in Table 1.

[0015] group
Embodiment 2
[0016] Example 2 Investigation of Conditions for Using Ethyl Acetate to Extract Folium Folium and Semen Cassiae Mixture
[0017] In this embodiment, the determination of the content of chrysophanol, the content of indirubin and the total solid yield in the extract is taken as indicators, and the orthogonal test method is adopted. The experimental design is shown in Table 2; the extraction process conditions of Semen Cassiae are preferred. According to the results of the preliminary test, select the factors and levels that affect the extraction effect, as shown in Table 3.

[0020] Preparation of the sample solution: Weigh Semen Cassiae and Folium Folium medicinal materials with a weight ratio of 2:1, according to the experimental method of the test column number in Table 3, use ethyl acetate as the solvent, respectively reflux extraction, filter, and concentrate to a constant volume. 250mL, set aside for later...
Embodiment 3
[0026] The preparation of embodiment 3 experimental samples
[0027] Weigh Semen Cassiae and Folium Folium with a weight ratio of 10:1, according to the optimal method in the examples, use ethyl acetate as a solvent, extract and combine the extracts, recover and make a dry paste, and prepare the experimental group I;
[0028] Weigh the Semen Cassiae and Folium Folium medicinal materials with a weight ratio of 1:10, according to the best method in the examples, use ethyl acetate as a solvent, extract and combine the extracts, recover and make a dry paste, and prepare the experimental group II;
[0029] Weigh Semen Cassiae and Folium Folium with a weight ratio of 3:1, according to the optimal method in the examples, use ethyl acetate as a solvent, extract and combine the extracts, recover and make a dry paste, and prepare the experimental group III;
[0030] The Semen Cassiae medicinal material was weighed, and according to the optimal method in the examples, ethyl acetate was u...
