The polyphenols were analyzed and identified by HPLC and the essential oils were chemically analyzed and identified by GC/MS. The principal components of myrtle leaves essential oil were 1,8-cineole (40.37%) and α-pinene (21.82%). Major oil components of myrtle berry essential oil included 1,8-cineole (46.48%) and α-pinene (24.52%). The essential oil of rockrose was characterized by a high content of 1,8-cineole (19.27%) and viridiflorol (16.38%), while the predominant compounds in montpellier cistus essential oil were 1,8-cineole (9.17%), bornyl acetate (9.14%) and α-pinene (5.84%). Myrtle berry contains small amounts of myricetin derivates (myricetin-3-O-galactoside and myricetin-3-O-rhamnoside), although anthocyanins (malvidin-3-O-glucoside, petunidin-3-O-glucoside) are present in large amounts. In Cistus ladanifer and Cistus monspeliensis the predominant flavonoids were 3,7′-di-O-methyl-kaempferol and 3-O-methyl-kaempferol.
