Mahanimbine C??? ??, ??, ??
??
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.?? ??
