Isolated from the fruit of Murraya koenigii Spreng. this base is closely allied to
the two preceding bases as may be seen from the structure. The ultraviolet
spectrum, however, differs from that of koenimbidine, having absorption maxima
at 230, 240, 300, 340 and 360 mJI. The double bond in the pyrone ring may be
reduced with the formation of the dihydro derivative, m.p. 250°C.
