At present, the research of Moutan cortex carbonisata (MCC) mainly focuses on the changes of chemical composition before and after charcoal production, and there is a lack of material basic research directly related to the efficacy at home and abroad. In this study, Moutan cortex, as a precursor, and was calcined to MCC at high temperature. The Moutan cortex carbonisata nano-components (MCC-NCs) were extracted and separated from MCC to explore its cooling-blood and hemostatic effects. In the experiment, the MCC was calcined at a high temperature in a muffle furnace (350℃, 1 h), and then MCC-NCs were extracted for MCC, and characterized by transmission electron microscopy and UV-vis absorption spectroscopy, fluorescence spectroscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. In addition, the study evaluated the bloodcooling and hemostatic effects of MCC-NCs. The results showed that MCC-NCs have a size distribution of 0.80-2.8 nm, a lattice spacing of 0.26 nm. MCC-NCs are mainly composed of C, O and N elements and have abundant surface functional groups such as OH, C=O, C-N and C=C. The fluorescence yield of MCC-NCs was 7.18%. The experiments complied with the Animal Ethics Committee of Beijing University of Chinese Medicine. The result indicated that pretreatment MCC-NCs can significantly (P < 0.05) reduce the high, medium, and low viscosity of whole blood and plasma viscosity, and reduce hematocrit, red blood cell distribution width, hemoglobin and red blood cell level. In addition, MCC-NCs significantly reduced the levels of activated partial thromboplastin time, thrombin time and fibrinogen (P < 0.05). The pathological examination results showed that MCC-NCs can significantly reduce lung tissue damage, reduce bleeding and inflammatory cell infiltration. At the same time, it can also significantly reduce the symptoms of gastric mucosal bleeding. In conclusion, the results indicated that MCC-NCs has significantly the effect of blood cooling and hemostasis, and its hemostatic effect is mainly related to the activation of endogenous coagulation pathway or fibrinogen system, which provided a novel strategy for exploring the material basis of traditional Chinese medicine for hemostasis.
