Chrysophanic acid
Chrysophanol, a natural ingredient highly regarded in the fields of medicine and scientific research, has a unique "identity" and value. Its chemical name is 1,8 - dihydroxy - 3 - methylanthraquinone, with a molecular formula of $C_{15}H_{10}O_{4}$ and a molecular weight of 254.23. In appearance, it usually presents as orange - yellow flakes or hexagonal and monoclinic crystals, exuding a unique crystalline beauty. In terms of solubility, chrysophanol is almost insoluble in water but can dissolve well in organic solvents such as boiling ethanol, benzene, chloroform, ether, glacial acetic acid, and acetone. This property endows it with specific applications in different extraction and preparation processes. Chrysophanol has rich pharmacological activities. In the field of antibacterial, it can exhibit inhibitory effects on various common pathogens, such as Streptococcus pneumoniae and Streptococcus hemolyticus, contributing to the fight against bacterial infections. In anti - tumor research, chrysophanol has shown remarkable performance. It can not only inhibit mouse melanoma but also suppress the proliferation of colon cancer cells by blocking the EGFR/mTOR pathway, bringing new hope to the difficult problem of conquering cancer. At the same time, it also plays a role in regulating blood lipids and improving metabolism. It can regulate fat metabolism and inhibit fat accumulation, potentially improving obesity - related problems. In nature, chrysophanol is widely distributed in a variety of plants. The root of Rheum palmatum, a plant of the Polygonaceae family, is one of its important sources. When people deeply study the medicinal value of these plants, chrysophanol stands out as a key active ingredient. In addition, the roots of plants such as Rumex patientia, Rumex dentatus, as well as the young roots and seeds of Cassia occidentalis, are also the "hiding places" of chrysophanol.
