1. Allelopathic interactions between invasive and native species have been suggested to be an important mechanism for the success of some of the most aggressive plant invaders. However, field experiments that test the effects of natural levels of allelopathic compounds on coexisting native species are exceptionally rare. 2. In this study, we analyzed the allelopathic effects of the invasive tre...

its capacity to generate a great number of radical sprouts. The spreading of Ailanthus in Cagliari’s district has led to high concentration of its pollen grains in April–June, as detected by the pollen trap. Although Ailanthus was mentioned in two ancient books of allergology (1, 2), has been ignored in the recent literature. The possible sensitization to Ailanthus pollen in patients suffering ...

The quassinoids are a group of complex, highly oxygenated, degraded triterpene mostly found in Simaroubaceae family. Two quassinoids (degraded triterpenes), 1 and 2 were isolated first time from the stem bark of Ailanthus excelsa. Compound 1 is C19 quassinoid. C19 quassinoid derived biogenetically from a C20 quassinoid, via a 1,2 – dioxo derivative. The structural elucidation is based on the an...

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

The invasion of ecosystems by non-native species is a major driver of biodiversity loss worldwide. A critical component of effective land management to control invasion is the identification and active protection of areas at high risk of future invasion. The Appalachian Trail Decision Support System (A.T.-DSS) was developed to inform regional natural resource management by integrating remote se...

Cyperus rotundus, Caesalpinia bonducella, Tinospora cordifolia, Gardenia gummifera, Ailanthus excelsa, Acacia arabica, Embelia ribes and Ventilago maderspatana from Melghat forest were screened for their antibacterial potential against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris, Salmonella typhi, Shigella flexneri, Salmonella paratyphi, Salmonella typhimuri...

A new quassinoid, ailantinol H, was isolated from the aerial parts of Ailanthus altissima. The structure was elucidated based on spectral evidence.
