Scalione has examined the essential oil of Butneria occtdentalis, or Calycanthus occidentalis, which he obtained to the extent of 0 27 per cent, of the leaves and twigs. The oil had the following characters —... 

Interconversion of these cyclitols has been demonstrated in the intact rat (PosTERNAK etul.y 1963) and in the plant Calycanthus occidentalis (Scholda et aL, 1964). In both cases good evidence was presented that myo-inosose-2 was an intermediate in the reaction ...

Folicanthine (6), Chimonanthine (7), mcsu-Chimonanthine (8), and Calycanthi-dine (9).—Folicanthine occurs in Calycanthus floridus L. and C. occidentalis Hook, et Arn. It follows from molecular weight determinations and the isolation of 1.6 moles of N, )iV(j,)-dimethyl-2,3-dihydrotryptamine (10) on zinc-acid reduction that it is a dimer of X( )A(j,)-dimethyltryptamine. Treatment of folicanthine dimethiodide with sodium hydroxide gives the key compound (11), whose structure follows from its ready acid-catalysed cleavage to the indole...
