Ascochyta rabiei (Pass.) Lab. is a highly destructive pathogen of chickpea. In thisstudy, leaf extract Eucalyptus citriodora was assessed against this pathogen. Bioassays withmethanolic (0, 05, 1.0, 1.5, …, 4.0%) revealed the remarkable antifungal potential ofleaf where 69–94% reduction in biomass A. recorded. Chloroform fraction thisextract separated by partitioning separating funnel. Using so...

A busca por produtos naturais que possam substituir preservantes da madeira sintéticos é crescente. Dentre estes produtos, estão os óleos essenciais (OEs). Portanto, o objetivo deste estudo foi avaliar a atividade antifúngica dos OEs de Blepharocalyx salicifolius, Nectandra grandiflora, megapotamica e Piper gaudichaudianum, sobre fungos apodrecedores Trametes versicolor Gloeophyllum trabeum. Os...

The volatile compounds obtained from the ether extracts, headspace gases and steam distillates of Alpinia japonica and Elettaria cardamomum were analyzed by GC/MS. Both species were rich sources of naturally rare fenchane-type monoterpenoids, fenchene, fenchone, fenchyl alcohol and its acetate, together with 1,8-cineole. The distributions of volatile sesquiterpenoids were very poor in both spec...

The chemical variations of the essential oil from the aerial parts of Laurus nobilis L. (Lauraceae) have been studied. Plant material has been harvested at each phenological status (vegetative, before anthesis, full flowering and seed-bearing). The oils were obtained by hydrodistillation of the air-dried samples. Analysis by GC and GC-MS of the essential oils has allowed to identify 39 compound...
