Gentianine
Gentianine is a pyridine-derived alkaloid. Originally isolated in 1944 from Gentiana kirilowi, it has also been found in Gentiana macrophylla, fenugreek, Strychnos angolensis, Strychnos xantha, and other plants. Gentianine is a crystalline solid with a melting point of 82-83 °C. It is a base that forms salts, such as the hydrochloride salt, upon treatment with acids. Gentianine has been studied for its potential anti-inflammatory properties. References
