Pandamarine

Pandamarine (343) was isolated as the major alkaloid in Pandanus amaryllifolius and its structure was determined by and 13C-NMR, and X-ray crystallography [724], Pandamarilactone-1 (344) was subsequently reported from P. amaryllifolius, its structure having been established by HRMS, 1R, UV, and one- and two-dimensional and 13C NMR [725],... 

Other natural products containing pyrrolones are holomycin (92), [166] the bile pigment bilirubin (93) [167] and pandamarine (94), isolated from the leaves of Pandanus amarillifolius Roxb [168]. 

Pandamarine (155) obtained from the leaves of Pandanus amaryllifolius (Pandanaceae), is surprisingly a racemic alkaloid, whose structure was determined by X-ray diffraction study (120). (See Fig. 15.)...
