Ailanthus Altissima (miller) Swingle: a Source of Bioactive Compounds with Antioxidant Activity

چکیده
Ailanthus altissima (Miller) Swingle is a tree used in Chinese traditional medicine as a bitter aromatic drug and in the treatment of colds and gastric diseases. Previous phytochemical studies have demonstrated the presence of quassinoids in the plant, as well as indole alkaloids. The purpose of this work was to determine the phenolic, flavonoid, and total alkaloid contents of the ethanolic, methanolic, acetone, and hydroalcoholic crude extracts of A. altissima and then try to correlate them with antioxidant activity of corresponding extracts. Moreover, the phenolic compounds present in the extracts were analyzed by RP-HPLC. Extracts from leaves have greater phenolic content than the other parts of this tree. Concerning the extraction process, it is possible to conclude that the mixture of water and ethanol is the best solvent to extract substances with antioxidant activity. Analysis by RP-HPLC showed that ferulic acid was the most dominant hydroxycinnamic acid, with an occurrence percentage of 25.59%. These results presented a positive linear correlation between antioxidant activity index and total phenolic content of all the extracts.

various biological activities, such as antitumor, antimalarial, antifeedant, insecticidal, antiinflammatory, amoebicidal, and herbicidal effects. We are interested in such biologically active compounds and have isolated many quassinoids from plants, such as Brucea antidysenterica, Picrasma ailanthoides, and Brucea javanica. As part of these studies, we investigated the isolation of quassinoids ...

Four novel compounds-two phenylpropionamides, one piperidine, and one phenolic derivatives-were isolated and identified from the fruit of a medicinal plant, Ailanthus altissima (Mill.) Swingle (Simaroubaceae), together with one known phenylpropionamide, 13 known phenols, and 10 flavonoids. The structures of the new compounds were elucidated as 2-hydroxy-N-[(2-O-β-d-glucopyranosyl)phenyl]propion...

Ailanthus altissima Swingle (Simaroubaceae) is commonly known as “Tree of heaven”. The methanolic extract of root bark of A. altissima (MEA) was taken for anti-diarrhoeal activity. Investigations were carried out on castor oil induced diarrhoea and small intestine transit method on mice. In former method, MEA 200 (mg/Kg) were reducing the total weight of the faeces of group (0.163±0.028) in com...
متن کاملAnalysis of intraspecific and interspecific interactions between the invasive exotic tree-of-heaven (Ailanthus altissima (Miller) Swingle) and the native black locust (Robinia pseudoacacia L.)
Invasive exotic plants can persist and successfully spread within ecosystems and negatively affect the recruitment of native species. The exotic invasive Ailanthus altissima and the native Robinia pseudoacacia are frequently found in disturbed sites and exhibit similar growth and reproductive characteristics, yet each has distinct functional roles such as allelopathy and nitrogen fixation, resp...
