Pandanus amaryllifolius Roxb. - Pandanaceae - syn.Pandanus latifolius Hasskarl (1842), not Perrot (1825); P. odorus Ridl.
pandan, edibel pandanus

Evergreen herb with aerial roots and branched stem, cultivated in Indonesia (West Papua), Malaysia, Philippines, Sri Lanka, Thailand, China and Vietnam. „leaf apex with 2 distinct lateral pleats and dense antrorse spines (prickles) ca. 1 mm along pleats…; female inflorescence unknown; male inflorescence (evidently exceedingly rare) probably pendent, to 60 cm“ http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242335482

Fresh leaves of P.amaryllifolius contain 2-acetyl-1-pyrroline (characteristic odor of white bread crust or basmati rice) at 10.3 mg/kg.

Volatile compounds of a dichloromethan extract of the leaves included 3-methy-2-(5H)-furanone (70%) as the main component, as well as 3-hexanol, 4-methyl-2-pentanol, 3-hexanone, ranging from 2-7% of the total volatiles, so the pandan extract had also fresh and green notes.

The dried leaves contain alkaloids of the pyrrolidine type, like Pandanamilactonines (A,B,C,D) and two others, as well as (6E- and 6Z-)pandanamine.

The roots contain also alkaloids of the pyrrolidine type, Pandanamilactones (E,F,F-N-oxide,G).
