[0021] Experimental example 1, pharmaceutical composition of the present invention is to L 615 Drug Efficacy Test in Leukemia Mice
[0022] 1. Sample preparation
[0023] 1. Extraction preparation
[0024] (1) Preparation of volatile oil and its clathrate: take 150g of succulent grass and 98g of Ganqing Qinglan, add 2500ml of water, use steam distillation to prepare volatile oil (3h), filter, and store the filtrate and filter residue separately;
[0025] (2) Add 5ml of collected volatile oil to 30g of β-cyclodextrin to clathrate the volatile oil to obtain 33g of volatile oil clathrate;
[0026] (3) Take the filtrate obtained in step (1), concentrate under reduced pressure to a clear paste with a relative density of 1.15-1.25 at 50° C., add ethanol to adjust to a volume percentage of 70% alcohol concentration, leave it at 2° C. for 24 hours, and filter. Discard the precipitate to obtain filtrate A;
[0027] (4) Take the herb dregs obtained in step (1), add 300g of cassia yu...

[0053] Experimental Example 2: For P 388 Pharmacodynamics Test in Leukemia Mice
[0054] 1. Modeling method: ascites type P 388 Leukemic mice were sacrificed by dislocation of the cervical spine, abdomen was disinfected, ascites was sucked, mixed with normal saline, and the cell concentration was adjusted under a microscope to be (1-1.5)*10(^7) cells / ml, 0.2ml per mouse (Kunming species) Inoculation concentration and dose of mice) were injected intraperitoneally.
[0055] 2. To P 388 The effect of natural killer cell (NKC) and interleukin-2 (IL-2) activity after chemotherapy in leukemia mice.
[0056] Materials: 50 first-class Kunming mice (Shandong Experimental Animal Center), 50 males and 50 males, weighing 18-22 g. Samples 1-4 (same as experimental example 1 sample, batch numbers are 20140321, 20140322, 20140323 and 20140324 respectively), cyclophosphamide (Jiangsu Hengrui Medicine Co., Ltd.), standard recombinant human interleukin-2 (Beijing Shuanglu Pharmaceutical Co....
Embodiment 1
[0069] A pharmaceutical composition for treating leukemia, which is composed of the following raw materials: 300g of Plum japonica, 175g of plateau buttercup, 150g of succulent grass, and 98g of Ganqing Qinglan.
[0070] Its preparation method is:
[0071] (1) Take the succulent grass and Ganqing Qinglan, add 10 times the volume of water of the total weight of the medicinal materials, use steam distillation to decoct for 5 hours, collect the volatile oil, filter, and store the filtrate and filter residue for later use;
[0072] (2) 5.5 ml of the collected volatile oil was clathrated with β-cyclodextrin with a volume-to-weight ratio of 6 times the weight to obtain 36 g of volatile oil clathrate;
[0073] (3) Take the filtrate obtained in step (1), concentrate it under reduced pressure to a clear paste with a relative density of 1.20 at 50° C., add ethanol to adjust to a volume percentage of 70% alcohol concentration, leave it at 2-10° C. for 24 hours, filter, Discard the preci...
