Cytotoxic Alkaloids from the Stem of Xylopia laevigata.
Xylopia laevigata (Annonaceae), known locally as "meiú" or "pindaíba", is widely used in folk medicine in Northeastern Brazil. In the present work, we performed phytochemical analyses of the stem of X. laevigata, which led to the isolation of 19 alkaloids: (-)-roemerine, (+)-anonaine, lanuginosine, (+)-glaucine, (+)-xylopine, oxoglaucine, (+)-norglaucine, asimilobine, (-)-xylopinine, (+)-norpur...
متن کاملViability of recently harvested and stored Xylopia aromatica (Lam.) Mart. (Annonaceae) seeds1
Xylopia aromatica is a native species from Brazil’s “Cerrado”, recommended for restoration ecology and also as a medicine. Its seeds have embryos with morphophysiological dormancy, making nursery propagation difficult. The objective of this study was to verify the efficiency of X-ray and tetrazolium tests for evaluating the viability of three seed lots, stored for different periods. All seeds w...
متن کاملAntitumour properties of the leaf essential oil of Xylopia frutescens Aubl. (Annonaceae).
The aim of this study was to investigate the chemical composition and anticancer effect of the leaf essential oil of Xylopia frutescens in experimental models. The chemical composition of the essential oil was analysed by GC/FID and GC/MS. In vitro cytotoxic activity of the essential oil was determined on cultured tumour cells. In vivo antitumour activity was assessed in Sarcoma 180-bearing mic...
متن کاملA new species of the lenticel fungal genus Claviradulomyces (Ostropales) from the Brazilian Atlantic forest tree Xylopia sericea (Annonaceae)
Claviradulomyces xylopiae sp. nov. is introduced for a fungus occurring in association with abnormal (enlarged, spongy) lenticels of Xylopia sericea (Annonaceae), a common tree of the Atlantic forest and Cerrado ecosystems in Brazil. This is the second species described in the genus and, although it is morphologically distinct from the type species, C. dabeicola from West Africa, it possesses t...
متن کاملAntifungal Aromadendrane Sesquiterpenoids from the Leaves of Xylopia brasiliensis
Um novo sesquiterpeno, aromadendrano-4β,10α,15-triol, foi isolado das folhas de Xylopia brasiliensis Spreng (Annonaceae), juntamente com quatro derivados de esqueleto aromadendrano e três esteróides. As estruturas dos metabólitos foram definidas por meio da análise dos respectivos espectros de RMN, incluindo experimentos bidimensionais, além de espectrometria de massas. Os sesquiterpenos aromad...
