• Description: As a Chinese medicine, brucine was firstly recorded in Compendium of Materia Medica. The Chinese name for brucine is “Maqian” because it looks like ancient coins with horse icon, where “Ma” refers to “horse” and “qian” refers to “coins.” This traditional Chinese herb has cold, bitter, and toxic properties. It can be used to treat typhoid fever, throat pain, and lumps. Brucine is mainly extracted from the traditional Chinese medicine “Maqian.” In 1819, Pelletier and Caventou firstly isolated the alkaline brucine from the seeds and bark of Strychnos nux-vomica L.?Brucine is the dry and mature seeds of Loganiaceae Evergreen tree plants including Strychnos nux-vomica L. and Strychnos pierriana A.W. Hill.
• Physical properties: Appearance: white crystalline powder; tastes very bitter. Solubility: slightly soluble in water; soluble in ether, chloroform, ethanol, methanol, and other organic solvents . Melting point: 175–178?°C. Specific optical rotation: ?118°.
• Uses: Brucine is used as a denaturing alcohol, lubricant additive, separation of racemic mixtures. Proposed to reduce inflammatory mediators including COX-2, PGE2 and thromboxane B2. Able to induce cell apoptosis, with cytotoxic and antiproliferative effects. Brucine occurs in the seeds of strychnosspecies (Strychnos nux vomica L. and otherspecies). It is used for denaturing alcoholsand oils; for separating racemic mixtures;and as an additive to lubricants. It is alsoused for colorimetric analysis of nitrate.Therapeutically, it is used as a stimulant. 10,11-Dimethoxystrychnine can be used for antineoplastic, convulsant.
• Clinical Use: The applications of brucine include reducing swelling; resolving mass; activating meridians to stop pain; attenuating rheumatism, stubborn paralysis, and numbness paralysis; alleviating bruises; etc. It has been used for nearly a thousand years and achieved prominent clinical efficacy. In the clinical practice, brucine is used as a compatibility prescription or compound medicine in treating rheumatism, rheumatoid arthritis, stroke hemiplegia, dementia, retinopathy, and orthopedic and other surgical diseases.Brucine is the main active ingredient in Strychnos and plays an important role in treating diseases. However, brucine is also a toxic ingredient, which limits the scope of its clinical application. Further studies of its pharmacological effects and toxicity will improve its clinical application.
