kopsinine Chemical Properties,Usage,Production

  • 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.
