Abstract

Essential oil is extracted from the leaves and fruits of Myrtle which are common types growing in the coastal province in Syria, Then a quality and quantity analysis was done using an apparatus called GC-MS.

Results showed that the Myrtle leaves are richer in oil (1.47%) than the fruits (0.33%). It has been determined thirty five chemical compounds in it, and noticed a difference in the quantities of these compounds, but the difference was limited between leaves and fruits. those compounds are mainly : α- pinene, 1,8- cineole, α-terpineol, linalool, linalyl acetate, α-terpinyl acetate, For the three types it was noticed that the leaves are richer in compounds: 1,8-cineole, linalool, α-terpineol, linalyl acetate, α- selinene, The fruits were richer in compounds: 3-carene, p-cymene, δ-terpinene, α-terpineol, α-terpinyl acetate, geranyl acetate, β- caryophyllene, caryophyllene oxide,
