This work is focused on nine Heracleum taxa (Apiaceae): H. sphondylium, sibiricum, montanum, ternatum, pyrenaicum subsp. pollinianum, orsinii and verticillatum, belonging to the sphondylium group, orphanidis, all from sect. Heracleum, as well austriacum siifolium Wendia. The aim was isolate headspace (HS) fractions 17 fruit samples (collected taxa) 13 root eight Heracleum), investigate their co...

The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...

Species distribution models are scarcely applicable to invasive species because of their breaking of the models' assumptions. So far, few mechanistic, semi-mechanistic or statistical solutions like dispersal constraints or propagule limitation have been applied. We evaluated a novel quasi-semi-mechanistic approach for regional scale models, using historical proximity variables (HPV) representin...

The essential oil of Heracleum sphondylium L subsp. ternatun (Velen.) Brummit (Umbelliferae) was isolated from crushed seeds by means of hydrodistillation and analyzed by GC and GC/MS. Major components were identified as 1-octanol (50.3%), octyl butyrate (24.6%), and octyl acetate (7.3%). Furthermore, antimicrobial activity of the oil was evaluated using microdilution broth and agar diffusion m...
