Ellis (Rubiaceae) were reported. The chemical constituents of the essential were analyzed using gas chromatography-flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). The hot plate and carrageenan-induced models were used to determine the anti-nociceptive and anti-inflammatory activities. The main compounds of the oil were pentadecanal 17 (49.2%), geranial 4 (12.3%), ar-turmerone 14 (8.2%) and 10-epi-γ-eudesmol 10 (6.2%). The essential oil of G. jasminoides at 100 and 400 mg.kg-1 doses significantly (p < 0.001) increased the latency period for the reaction duration in the anti-nociceptive study. The carrageenan-induced edema model reveals the suppression of inflammatory mediators (p < 0.001) within 1st, 2nd and 4th h for 100 mg.kg-1 dose, 1st and 4th h (200 mg.kg-1) and 1st-3rd h (400 mg.kg-1). The results indicate the potential of G. jasminoides essential oil as a source of pain relieving agent. Manuscript profile -

Chev (Combretaceae) collected from Kaduna, Northern Nigeria, are reported. Essential oils were obtained using hydrodistllation in a Clevengertype apparatus. The yield of the light yellow oil was found to be 0.22% (v/w, dry weight basis). The content and composition of the oil were analyzed by gas chromatography (GC-FID) and gas chromatography with electron impact mass spectrometry (GC-MS). The main compounds of the oil were δ-3-carene (29.4%) and α-pinene (20.9%). To the best of our knowledge, this is the first report on the essential oil constituents of any part of T. ivorensis.
