Pandanus

Occasional positive tests for alkaloids have been noted earlier in the family. Here, of 22 samples representing 18 species, only three gave positive tests Galearia celehica, Microdesmis puberula (branches), and Pandanus teciorius (1/3).

Ethers. We have previously considered the phenolic ethers, which are quite a significant group, but there are also others, e.g. phenyl ethyl ether found in pandanus essential oil.

The structures of two new pyrrolidine alkaloids, pandamarilactonine-A and -B isolated from Pandanus amaryllifolius Roxb, have been deduced by Takayama and co-workers with the help of vicinal Jhc and /hh couplings. Girault and co-workers have determined conformations of free and ribosome-bound macrolide antibiotics using NMR and molecular modelling. The authors analysed Vhc and /hh couplings of the proline and sugar part of lincomydn and clindamycin and of the macrocycle as well as desosamine part of HMR 3647 (telithromycin). ... 

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.)...
