Abstract:
Lodoicea maldivica (J. F. Gmel.) Pers. (Arecaceae), ‘Coco de Mer’, is a palm, growing as endemic in the Seychelles islands. Its
fruit weighs up to 20 kg and is characterized by a fleshy and fibrous envelope surrounding the nutlike portion. The present
work combines a morpho-anatomical and a phytochemical analysis of the fruit exocarp and mesocarp.
The exocarp is composed by a layer of palisade cells. The mesocarp is characterized by vascular bundles and by sclereids. In
the aerenchyma, the internal zone of the mesocarp, cells aggregates were positive to phenols, while idioblasts were positive
to terpenes.
We performed a GC-MS analysis with a semi-quantitative relative amount calculation of the recorded compunds.
The GC-MS essential oil profile revealed the dominance of acyclic sesquiterpenoids (53.95%), followed by bicyclic
sesquiterpenoids (31.69%), monoterpenes (11.89%) and monocyclic sesquiterpenoids (2.44%).
The terpens detected in higher amounts, β-caryophyllene and bicyclogermacrene, are known for activity against insect
larves, but have been proposed as anti-viral candidates with against SARS-CoV-2. The third compound in amount,
aromadendrene, is active against bacteria and, again, known to possess insecticidal properties.
