background: nowadays candida albicans has become resistant to the toxic and expensive commercial anti-candida drugs. therefore, investigation for new anti-fungal agents is necessary. objectives: the purpose of this survey was to investigate the in vitro anti-candida activity of the hydroalcoholic extracts of heracleum persicum fruit. materials and methods: the plant ingredients were extracted u...

CONTEXT Effective drugs to treat osteoarthritis (OA) and inflammatory bowel disease (IBD) are needed. OBJECTIVE To identify essential oils (EOs) with anti-inflammatory activity in cell models of OA and IBD. MATERIALS AND METHODS EOs from Eryngium duriaei subsp. juresianum (M. Laínz) M. Laínz (Apiaceae), Laserpitium eliasii subsp. thalictrifolium Sennen & Pau (Apiaceae), Lavandula luisieri (...

Heracleum mantegazzianum has been the focus of a 40 month in depth study by eight research groups across Europe, one of the most detailed studies undertaken in Europe of a nonagricultural weed. Lessons learned from this research are linked to investigations of other alien invasive species and their management. The value of understanding the ecology of the species in its native range is consider...

Two S-adenosyl-L-methionine:furanocoumarin O-methyltransferases of R. graveolens, acting at the 5- and 8-hydroxyl of the psoralen nucleus, were completely resolved by adsorption on a general affinity ligand, 5-(3-carboxypropanamido) xanthotoxin, followed by specific desorption by bergaptol and xanthotoxol, respectively. The 5-O-methyltransferase was purified 450-fold by this procedure, the 8-O-...

chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of  heracleum rechingeri manden. were analyzed by gc and gc/ms. twenty-four components were characterized for the leaf oil with octyl acetate(47.2%), octanol(15.2%) and e-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with elemicin (65.3%), octyl acetate (13...
