Preliminary phytochemical screening for antioxidant activity and content of phenols and flavonoids of 18 species of plants native to western Ecuador
The phytochemical screening, total phenolics and flavonoids content and antioxidant activity of plants native to western Ecuador were investigated to provide the basic information for further studies towards the discovery of new compounds. The species studied were Adenostemma platyphyllum Cass, Castilla elastica subsp . gummifera (Miq.) C.C. Berg., Cochlospermum vitifolium (Willd.) Spreng., Ectozoma pavonii Miers, Erythrochiton giganteus Kaastra & A.H. Gentry, Erythroxylum patens Ruiz ex O.E.Schulz, Ficus brevibracteata W.C. Burger, Ficus tonduzii Standl., Grias ecuadorica Cornejo & S.A. Mori, Handroanthus billbergii subsp . ampla (Bureau K. Schum.) S.O. Grose, Morisonia americana L., Operculina codonantha (Benth.) Hallier f., Passiflora macrophylla Spruce ex Mast., Podandrogyne jamesonii (Briq.) Cochrane, Pradosia montana T.D. Penn., Tecoma castaneifolia (D.Don) Melch, Urera baccifera (L.) Gaudich. ex Wedd., and Xanthosoma sagittifolium (L.) Schott.The highest percentage of inhibition of DPPH• was found in E. patens (92.41%). Most of the extracts evaluated exhibited antioxidant activity.
期刊介绍：
Town Planning Review has been one of the world"s leading journals of urban and regional planning since its foundation in 1910. With an extensive international readership, TPR is a well established urban and regional planning journal, providing a principal forum for communication between researchers and students, policy analysts and practitioners. To mark TPR’s centenary in 2010, it is proposed to publish a series of ‘Centenary Papers’ -- review papers that record and reflect on the state of the art in a range of topics in the general field of town and regional planning.
