Beschreibung
The roots and leaves of Murraya koenigii Spreng. yield this alkaloid which is
best crystallized from CH2 C1r hexane. It has [α]
D - 6° (c 2.01, CHC1 3 ) and the
ultraviolet spectrum in EtOH shows absorption maxima at 225, 278, 281, 295,
335 and 354 mp. Catalytic hydrogenation with Pd-C gives the tetrahydro deriva_x0002_tive, m.p. l66-7°C, as colourless crystals from pentane, the ultraviolet spectrum
of which has absorption maxima at 220, 241, 255,260,306 and 320 mp. Treatment with methyl sulphate in NaOH yields the N-methyl compound, m.p. 94°C,
giving an ultraviolet spectrum in EtOH consisting of absorption maxima at 240,
293,332,345 and 358 mp.
