  • Tree form has an Erect trunk(15cm wide) which produces thick aerial roots.
  • Leaves of the tree form are the same shape, but about twice the size (7 - 9 cm wide, 150 - 220 cm long) , Leaves are spirally arranged.
  • Flowers: only male flowers are found which also very rare it has spike of flowers with a white spathe.
  • No production of fruits due to lack of female inflorescences.

Active Phytochemicals

1. Over time, research has shown that Pandanus amaryllifolius Roxb. is rich in a wide range of compounds, of which several have pharmacological potential.
2. As reported histochemical and preliminary phytochemical screening provides the general idea regarding the presence of primary and secondary metabolites revealed the presence of phytoconstituents such as alkaloids, terpenoids, flavonoids, saponins, anthraquinone glycoside and cardiac glycoside
3. It is also mentioned that carbohydrate, tannins, flavonoids and saponins are present in the ethanolic extract of Pandanus amaryllifolius.
4. A previously conducted study showed that compounds like flavonoids and saponins might be responsible for the antidiabetic activity
5. Pandan leaf extract contains the free amino acids and reducing sugars such as glutamic acid, proline, glucose, and fructose as possible precursors to ACPY (2-acetyl-1-pyrroline) and might play significant role in the aroma ACPY formation.
6. The major volatile compound in heated pandan and unheated pandan are 3-methyl-2(5H)-furanone followed by ACPY and 3-Methyl- 2(5H)-furanone respectively.
7. They also found that ACPY is the only compound that possessed pandan aroma characteristic by using GCO (gas chromatography-olfactometry) analysis . 8. The presence of 2AP(2-Acetyl- 1-Pyrroline) was also determined using GCMS by using ethanol as the solvent to extract 2AP from Pandan leaves and the higher 2AP peak arises from ethanol chromatogram
9. Additionally 30 aroma components also have been found of which the main ones are hexanal, 2-hexenal, 3-methyl pyridine, 2-penten-1-ol, nonanal, benzaldehyde and linalool .
10. In the study, suggested that pandan extracts showed good potential of bioactive compounds such as catechin, gallic acid, kaempferol and naringin. Pandan leaves contains Gallic acid, catechin, caffeic acid, myricetin, luteolin, and quercetin.
11. It is also reported that Pandanin, (mannose-binding protein) appears to be present in the saline leaf extract in minute amount elicits antiviral activity.
12. Pandan leaves contain certain alkaloids like Norpandamarilactonine-A,-B, Pandamarilactam 3x,-3y, Pandamarilactone-1, Pandamarilactonine A,-B,-C, Pandamarine, Pandanamine.
13. The other alkaloids (such as, pandanamine, pandamerilactones) with pyrroline-derived structures are also found in the leaves.
14. In-depth phytochemical analysis has confirmed the presence of several compounds such as essential oils, tocopherols, tocotrienols, alkaloid, fatty acids, esters non‐specific lipid transfer protein, carotenoids and flavonoids that act as a natural antioxidant and antidiabetic agents.
15. PA leaf extract demonstrated higher antioxidant activity than that of root extract. The major flavonoid in plant is quercetin, which belongs to a flavonol class that could inhibit α‐glucosidase enzyme by acting as a noncompetitive inhibitor.
