Four commonly used spices plants in Iran were evaluated for cytotoxicity effect using Brine Shrimp Lethality (BSL) assay. Essential oils and various extracts of Heracleum persicum, Nigella arvensis, Cinnamomum zeylanicum and Zingiber officinale were assessed by two methods of disk and solution of BSL. Data were processed in probit-analysis program to estimate LC50 values. All of the tested frac...

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...

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...

Ethnolinguistic studies are important for understanding an ethnic group's ideas on the world, expressed in its language. Comparing corresponding aspects of such knowledge might help clarify problems of origin for certain concepts and words, e.g. whether they form common heritage, have an independent origin, are borrowings, or calques. The current study was conducted on the material in Slavonic,...

The essential oil from the flowering aerial parts of Heracleum lanatum Michx. family Apiaceae was obtained by hydrodistillation and analysed by combination of GC (RI) and GC-MS. The chemical composition of the isolated oil is reported for the first time. Sixty five compounds were identified representing 96.95% of the total oil. The chemical composition of the isolated oil was characterised by a...

The ability of giant hogweeds to form monodominant communities and even pure monostands in invaded areas has been well documented. Understanding of the mechanisms leading to monostand formation can aid in determining the limitations of existing community ecology models and establishing an effective management plan for invasive species elimination. The aim of this observational study was to inve...
