Table 2: Composition (\(>\)/=0.1%) of volatile compounds of hydrodistillates from rhizomes with roots of _Filipendula vulgaris_. Figure 2: Representative chromatogram (GC-MS) of the volatiles from _F. vulgaris_ rhizomes with roots. As can be seen from the data presented in Table 3, the most pronounced cytotoxic effect on cancer cells was exerted by the aqueous-alcoholic extract of the _F. vulgaris_ rhizomes with roots, which at a dose of 0.50 mg caused 66% death of tumour cells. The aqueous extract at a dose of 0.50 mg/kg caused 48% death of cancer cells. The established cytotoxic effect on cancer cells of the FHE1 extract necessitated additional experimental studies of the effects of the _F. vulgaris_ aqueous and aqueous-alcoholic extracts on the animals' lifespan, the development of ascites fluid, and some biochemical parameters. The effects of the _F. vulgaris_ extracts on the growth of [PERSON]'s ascites carcinoma (volume of ascitie fluid) are presented in Figure 4.  
The growth inhibition coefficient of [PERSON]'s ascites carcinoma under the influence of the _F. vulgaris_ aqueous and aqueous-alcoholic extracts was determined on the 7 th and 14 th days of the experiment. They were 39.1% and 30.6%, respectively, for the aqueous extract FHE1, and 62.3% and 65.8%, respectively, for the aqueous-alcoholic extract FHE2. Thus, the aqueous-alcoholic extract of _F. vulgaris_ rhizomes with roots in the treatment of [PERSON] ascites carcinoma exhibited a more pronounced antitumor effect. Haematopoiesis indicators in the dynamics of the development of [PERSON] ascites carcinoma during the treatment are presented in Table 3.  
Analysis of the results of indicators of erythrocytes, leukocytes, and haemoglobin content (Table 4) shows that in the process of Ehrlich carcinoma growth in mice of the control group, along with an increase in the content of ascites fluid in the peritoneal cavity, a significant decrease in the number of erythrocytes and haemoglobin in the blood was observed on the 7 th and 14 th days of the study. Meanwhile, the level of leukocytes increased sharply and by the end of the experiment exceeded the norm by 2.2 times.
