The leaves of Murraya koenigii Spreng. also furnish this crystalline alkaloid
which is dextrorotatory with [α]D + 52° (CHCI3). The ultraviolet spectrum
exhibits several absorption maxima occurring at 227, 288,300,315,328,343
and 357 mil. It furnishes a crystalline picrate as pale yellow needles, m.p. 142°C
and on catalytic reduction gives the dihydro derivative, m.p. 101°C and finally
the tetrahydro compound, m.p. 108°C. Spectroscopic and chemical data support
the structure given above. | [Definition]
