Ocimum basilicum essential oil (Algerian species), which is extracted from dried leaves with an output of 1.98 ± 0.01%, is yellow pale. Its chemical composition has been investigated by GC/MS and GC/FID. Fourty compounds have been identified accounting for 97.4%. The major compounds were: Linalool (32.83%), linalyl acetate (16%), elemol (7.44%), geranyl acetate (6.18%), myrcene (6.12%), allo-ocimene (5.02%), α-terpineol (4.9%), (E)-β-ocimene (3.68%) and neryl acetate (3.45%). O. basilicum essential oil was screened for its in vitro antioxidant activity using DPPH assay. The results showed that the concentration of the essential oil needed to scavenge 50% of DPPH, was 83.54 mg/ml lower than that of vitamin E (22.0 mg/ml) and therefore acts as a natural antioxidant agent.

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 %). [less ▲]

The essential oil of three plants (Salvia officinalis, Thymus vulgaris and Ruta chalepensis) collected from Chlef, in the north west of Algeria, was isolated by steam distillation and investigated by GC and GC/MS. The yield of essential oil (g/100g) was 1.6% for Salvia officinalis, 2.6% for Thymus vulgaris and 1.1% for Ruta chalepensis. The Salvia officinalis was mainly composed of b-thujone (25%), camphor (23.6%), 1,8-cineole (21.5%), viridiflorol (9.5%) and a-thujone (6%). The main constituents of Thymus vulgaris were carvacrol (48.4%), g -terpinene (14.9%), p-cymene (14.7%) and thymol (5.6%) while 2-undecanone (83.2%) constituted the major component of Ruta chalepensis essential oil.
