The aim of the present experiment was to study the relationship between secondary metabolites content (phenol and flavonoid) and antioxidant activity in root, stem, leaves, and fruits of Heracleum gorganicumRech. F. The various parts of plant were collected in Ziarat Mountainin Golestan province. Total phenolics (TP) and total flavonoids (TF) contents were determined spectrophotom...

Heracleum Sosnowskyi was discovered in 1772 and described as a separate species in 1944 by I. P. Mandenova. Its name is derived from the surname of a botanist studying Caucasian flora, Prof. D.I. Sosnowski. In the area of the Caucasus foothills, the plant reaches approximately 1-1,5 m in height, whereas in Poland its size is significantly larger, up to 3-3.5 m. Heracleum blooms from mid-June to...

PURPOSE Two plant essential oils (EOs), including those from Heracleum transcaucasicum and Heracleum anisactiss (Umbeliferae) were studied to detect the chemical constituents and evaluated for their antibacterial activities against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. METHODS The EOs of H. transcaucasicum and H.anisactis (Apiacae) wer...

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. Applications...

Many exotic plant invaders pose a serious threat to native communities, but little is known about the dynamics of their impacts over time. In this study, we explored the impact of an invasive plant Heracleum mantegazzianum (giant hogweed) at 24 grassland sites invaded for different periods of time (from 11 to 48 years). Native species' richness and productivity were initially reduced by hogweed...

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...

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...
