Aniba duckei

Nicotine has been found in Anthoceris tasmanica (Solanaceae). Anibine (36) and a new alkaloid duckein are found in the trunk wood of Aniba duckei (Lauraceae). The latter is formulated as (37) on mass and n.m.r. spectral evidence. 

The South American rosewood, Aniba duckei Kostermans and Aniba rosaodora Ducke, family Lauraceae, contains an alkaloid, anibine, C11H9NO3 (mp 179°-180° picrate, mp 199°-201° hydrochloride, mp 205°-230° decomp. methiodide, mp 233°-236°) shown to have structure CXXXIV [192). Saponification of anibine with potassium hydroxide... 

Anibine (55) and duckein (56), from Aniba duckei (Laur-aceae), are components of commercial rosewood oil (Fig. 28.22). These compounds appear to be derived by extension of a nicotinoyl precursor by two or three acetate units, respectively (Strunz and Findlay, 1985). 

Occurs in Coto rind (Nectandra coto). Also from wood of Aniba duckei. Yellowish cryst. (H2O). Mp 130-131°. Reduces Fehling s soln. and NH3.AgN03 slowly in the cold.
