N2  - A number of homonuclear and heteronuclear 2D-n.m.r. techniques have been used to interpret completely the 1H n.m.r . spectrum and to reinterpret the 13C n.m.r . spectrum of the alkaloid anopterine. Comparison of the n.m.r . data for anopterine with those of six minor alkaloids from Anopterus macleayanus has allowed the assignment of the structures, 7&#946;-hydroxyanopteryl 11&#945;,l2&#945;-ditiglate, 7&#946;-hydroxyanopteryl 11&#945;-(E)-4&#8242;-hydroxy-2&#8242;-methylbut-2&#8242;-enoate 12&#945;-tiglate, anopteryl 12&#945;- tiglate , anopteryl 11&#945;-4&#8242;-hydroxybenzoate 12&#945;-tiglate, 7&#946;- hydroxyanopteryl 11&#945;-4&#8242;-hydroxybenzoate 12&#945;-tiglate and 7&#946;- hydroxyanopteryl 11&#945;-benzoate 12&#945;-tiglate to the minor alkaloids.
