Shrnutí:Background Pollen Typhae Carbonisata (PTC) is a type of calcined herb drug that has been used as a hemostatic medicine to promote hemostasis for thousands of years. In this study, we discovered and separated novel water-soluble carbon quantum dots (CQDs, named PTC-CQDs) from aqueous extracts of PTC. These PTC-CDs were characterized using transmission electron microscopy (TEM) and high-resolution TEM, as well as Fourier transform infrared, ultraviolet–visible, and fluorescence spectroscopy. Then, we assessed the anti-hemorrhagic effects and related hemostatic mechanisms of the obtained PTC-CQDs. Results The PTC-CQDs separated from PTC are spherical, monodisperse, and have a narrow size distribution between 2 and 8 nm. In the pharmacology experiment, remarkable anti-hemorrhage effects of PTC-CQDs were revealed. Additionally, the rats showed a profound decrease in activated partial thromboplastin time and increase in fibrinogen and PLT after PTC-CQDs treatment. Conclusions These results indicated the explicit hemostasis effect of PTC-CQDs, which not only provided a new idea for the material research of PTC, but have also provided new insights into potential biomedical and healthcare applications of CQDs in the field of haemorrhage control and laid a solid foundation for future drug discovery.
