As early as 1886, it was discovered that the active principle of the areca nut was alkaloidal in nature (75) and since then six alkaloids from that source have been characterized they are arecoline (76), arecaidine (76), (arecaine (78)), guvacine (78), guvacoline (81), isoguvacine (79), and arecolidine (80). The structure of the first four of these has been completely elucidated, but little is known of that of arecolidine, and the homogeneity of isoguvacine is uncertain. 

For many years after Jahns work (77) numerous papers appeared concerning the alkaloid arecaine which, according to Jahns, was isomeric, but not identical, with arecaidine. Eventually, the two bases were shown to be identical (98), but the confusion had again brought into question the structure of guvacine (87). However, structure XVI for guvacine was later confirmed by Freudenberg (99, 100).
