| | kopsinine Usage And Synthesis |
| Description | Present in Kopsia longijlora, this base is purified by crystallization from light
petroleum when it forms colourless crystals. It has [α]23D - 76.9° (c 2.09,
CHC1 3). It forms a crystalline dihydrochloride with m.p. 253-4°C, a mono_x0002_methiodide, m.p. 265-6°C and a monopicrate, m.p. 222-3°C. The N-formyl
derivative is identical with aspidofractine (q.v.). | | Uses | Kopsinine is an indole alkaloid extracted from periwinkle flowers[1]. | | Definition | ChEBI: A natural product found in Kopsia grandifolia. | | References | Crow, Michael., Austral. 1. Chem., 8, 129 (1955)
