This amorphous alkaloid was first isolated from Uncaria kawakamii, subsequently
being found in other Uncaria species and also in Ourouparia formosan a Matsumara.
The base is dextrorotatory having [α]D + 106.5° and gives a hydrochloride
hemihydrate as colourless needles, m.p. 231°C (dec.) and the N-acetyl derivative,
m.p. 165°C. The stereochemistry of this alkaloid has been revised comparatively
recently.
