Immature fruit oil of Brillantaisia lamium Benth. from Benin

The essential oil of air-dried immature fruit of Brillantaisia laminum (Acanthaceae) from Benin was analyzed by high resolution GC and GC/MS. Almost forty components were identified, representing more than 90% of the oiL The main constituents were isobornyl acetate (66.9%), caryophyllene oxide (5.0%), beta-caryophyllene (4.5%) and isoborneol (2.4%)

Volatile constituents of the peel and leaf oils of Citrus limon L. Burm. f. from Benin

The peel and leaf oils ofCitrus limon L. from Benin were analyzed by capillary GC on two columns of different polarity, and by GCIMS. In these oils 42 and 27 components were identified, representing over 99.7% ofthe oils. The main constituents of the lemon peel oil were limonene (70.4%), y-terpinene (11.8%) and beta-pinene (4.2%). The leaf oil consisted mainly of limonene (40.8%), beta-pinene (18.5%) and citronellal (16.5%)

Essential oil of Hexalobus monopetalus (A. Rich) Engl. leaves from Benin : a new source of citral

The leaf oil of Hexalobus monopetalus (Annonaceae) from Benin was analyzed by high resolution GC and GC/MS. Forty components were identified, representing more than 95% of the oiL The main constituents were geranial (37,9'lAl), neral (30,9%), linalool (35%), (E)-anethole (2.6%), selin-ll-en-4a-ol (25%) and caryophyllene oxide (2.4%)

Influence of Fruit Conservation Methods on the Essential Oil Composition of Xylopia aethiopica (Dunal) A. Richard from Benin

The fruits of Xylopia aethiopica (Dunal) A. Richard (Annonaceae) from Benin, commercially conserved in two different ways, were subjected to steam distillation. The resulting essential oils were analysed by high-resolution GC and HRGC-MS. For comparison, the leaf oil and fresh fruit oil of X. aethiopica were analysed as well. The oils were found to contain 50-60 components, of which about 40-45 constituents have been identified, accounting for more than 95% of the oils. The major components appeared to be -pinene (4-16%), sabinene (3-35%), -pinene (12-42%), 1,8-cineole (trace-15%) and (Z)ocimene (trace-18%). The leaf oil contained, in addition to these constituents, 14.9% of elemol
