Plant material was collected in October 2003. in Herceg Novi, Montenegro. The air-dried roots (54 g), seeds (73.5 g) and aerial parts during vegetative phase (V, 150 g) and aerial parts during flowering period (F, 110 g) of P. ramosissima were submitted for 3 h to water-distillation using a Clevenger type apparatus.

In all the oils samples the main component was myristicin. In the root oil myristicin was present with 68.5%, in oil from aerial parts during vegetative phase, myristicin was present with 88.9%, while in oil from aerial parts during flowering period this component was present with 91.5%, in the seed oil myristicin was found with 61.1%. It can be seen that myristicin was the most abundant component in all oil samples that we investigated with very high percentage. But, it can also be seen that the season of plant collection influenced the oil characteristics. The highest content of myristicin was present in the oil sample isolated from plants collected during the flowering period (91.5%), than in oil isolated during the vegetative phase.
