Heracleum is the widest genera of Apiaceae family. Of more than 120 species, 25 are presented in Caucasus, while 23 distributed to Georgia, from which 5 species endemic. According literature, only 1/6 of Heracleum species have been studied phytochemically so far. Plants this genus contain aromatic compounds and considered be a very rich source essential oils diverse furanocoumari...

This study reports the isolation and polymorphism characterization of four plastid indels and six nuclear microsatellite loci in the invasive plant Heracleum mantegazzianum . These markers were tested in 27 individuals from two distant H. mantegazzianum populations. Plastid indels revealed the presence of five chlorotypes while five nuclear microsatellite loci rendered polymorphism. Application...

BACKGROUND Plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. The aim of this study was to evaluate the larvicidal activity of essential oils of three plants of Apiaceae family against Anopheles stephensi, the main malaria vector in Iran. METHODS Essential oils from Heracleum persicum, Foeniculum vulgare and Coriandrum sativum seeds were hyd...

Ziel des Projektes indiGo war die Entwicklung einer integrierten Lösung für prozessorientiertes Wissensmanagement in Software Engineering Umgebungen [Rech et al, 2004] [Rech und Althoff, 2004]. Dadurch wird die verteilte und kollaborative Einführung, Evaluation und Verbesserung von Prozessmodellen in einem Unternehmen ermöglicht. Dieser Beitrag stellt die Ergebnisse des indiGo-Projekts vor und ...

The B. subtilis DhelD allele rendered cells proficient in transformational recombination and moderately sensitive to methyl methanesulfonate when present in an otherwise Rec strain. The DhelD allele was introduced into rec-deficient strains representative of the a (recF strain), b (addA addB), g (recH), « (DrecU), and z (DrecS) epistatic groups. The DhelD mutation increased the sensitivity to D...

The chemical composition of the essential oil obtained from the aerial flowering parts of Ziziphora clinopodioides subsp. bungeana (Juz.) Rech. f. was analyzed by GC and GC-MS. Thirty-two components representing 97.1% of the total oil were identified. Oxygenated monoterpenes (94.3%) were the predominant fraction of the oil with pulegone (65.2%), isomenthone (11.9%), 1,8-cineole (7.8%) and piper...

The cytotoxic chloroform fraction of Euphorbia aellenii afforded two cycloartane type triterpenes — cycloart-25-en-3,24-diol (1) and 24-methylene-cycloartan-3-ol (2) — for the first time from this plant. Preparation of cycloartane derivatives, 3, 24-O-diacetyl-cycloart-25-en as compound 3 and 3-O-acetyl-24-methylene-cycloartan (4) were conducted by acetylating of 1 and 2, respectively. The ...
