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.

Aerial parts of both varieties(Salvia euphratica Montbret et Aucher ex Benth. var. euphratica and Salvia euphratica Montbret et Aucher ex Benth. var. leiocalycina) were collected in Malatya, Turkey in June 1999.

Ninety-five compounds in var. euphratica and 94 compounds in var. leiocalycina were characterized representing 93% and 95% of the total components detected, respectively, with 1,8-cineole (13.8% and 15.2%) and myrtenyl acetate (15.9% and 13.9%) as main constituents.

Plant material and isolation procedure: Aerial parts of the plant were collected from two regions, from Kazeroon in southern Iran and Shahr-e-kord in western Iran at the time of flowering in June 2002.

The main components of the oil of S. pilifera collected from Kazeroon, in southern Iran, were spathulenol (15.8%), cis-chrysanthenol (15.3%), beta-caryophyllene (8.4%) and cis-chrysanthenyl acetate (6.9%), while for the plant collected from Shahr-e-kord, in western Iran, they were cis-chrysanthenyl acetate (21.8%), linalool (18.9%), terpinen-4-ol (11.9%) and cis-chrysanthenol (9.2%).
