to investigate the effects of deficit irrigation and different levels of nitrogen fertilizer on somequantitative and qualitative properties of melissa, a pot experiment was conducted for one year (2011) inmazandaran province. experiment was carried out as a factorial based on randomized complete blockdesign with three replications. irrigation treatments (25, 52 and 75 percent field capacity, fc...

As part of ongoing research on the chemical composition and the antimicrobial properties of Burkinabe plants essential oils alone and in combination, essential oils (EOs) from leaves of Cymbopogon citratus and Cymbopogon giganteus from Burkina Faso were analyzed by GC-FID and GC-MS. Five constituents, which accounted for 96.3% of the oil, were identified in the EO of C. citratus. Geranial (48.1...

Litsea cubeba (Lour.) Pers. is a promising industrial crop with fruits rich in essential oils. The chemical composition of essential oils of L. cubeba (EOLC) were determined for fruits harvested from eight regions in China. The overall essential oil content, obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS), ranged from 3.04% to 4.56%. In total, 59 compo...

Damask rose (Rosa damascena Mill.) is one of the most high-value essential oil-bearing plants in the world. However, the flower yield and quality of essential oil of R. damascena are largely influenced by the pruning practices and balanced supply of plant nutrition. The objective of this study was to test the hypothesis whether the pruning system and foliar fertilization of MgSO4 would influenc...

Changes in essential oil during ensiling of lemongrass and lemon eucalyptus were studied. Wilted lemongrass and eucalyptus leaves were ensiled in 0.25-L anaerobic jars. Samples consisted of a control (no additives) and a treated sample (0.5% glucose and lactic acid bacteria and 1% cellulase plus 1% hemicellulase plus pectinase). Three jars per treatment were sampled on days 2, 6, 10, and 36 for...

The composition and pharmacological properties of Lippia alba (Mill.) (L. alba) (Verbenaceae) flower leaf essential oils (EO) were determined in this study. major constituents the EO geranial (49.83%) neral (32.75%), (38.06%), (31.02%), limonene (18.03%). Flower inhibited thrombolysis induced by Bothrops moojeni (B. moojeni) Lachesis muta muta) venoms (0.05-1.2 µL mL-1). When tested against L. ...

Commercial plant essential oils from 26 plant species were tested for their nematicidal activities against the pinewood nematode, Bursaphelenchus xylophilus. Good nematicidal activity against B. xylophilus was achieved with essential oils of ajowan (Trachyspermum ammi), allspice (Pimenta dioica) and litsea (Litsea cubeba). Analysis by gas chromatography-mass spectrometry led to identification o...
