Abstract :
[en] The constituents of essential oils isolated by hydrodistillation of the overground parts of Ocimum basilicum L. and Ocimum gratissimum L. from Algeria were examined by GC and GC-MS. A total of 46 and 43 components were identified accounting for 99.4 % and 97.7 % of O. basilicum and O. gratissimum oils, respectively. The oil of O. basilicum contained, as main components, linalool (44.7 %), linalyl acetate (14.0 %), 1,8-cineole (6.7 %), myrcene (5.6 %), α-terpineol (5.1 %), geranyl acetate (4.0 %), alloocimene (2.4 %), neryl acetate (2.4 %), elemol (2.1 %) and β-caryophyllene (1.3 %). Major compounds in the essential oil of O. gratissimum were eugenol (54.8 %), β-elemene (10.9 %), 1,8 cineole (4.1 %), α-humulene (3.8 %) linalool (2.1 %) and α-amorphene (2.1 %).
