Cytotoxic Alkaloids from the Stem of Xylopia laevigata [PDF]

Molecules, 2016
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 ...

Guaiane dimers from Xylopia vielana

Phytochemistry, 2001
From the leaves of Xylopia vielana (Annonaceae) the three dimeric guaianes vielanin A-C were isolated and structurally elucidated by mass and NMR spectroscopy as 1-3. The structure of 1 contains a bridged ring system formed probably via a Diels-Alder reaction of two different guaiane monomers. Compounds 2 and 3 represent symmetric cyclobutanes formally

HPLC quantitation of kaurane diterpenes in Xylopia species

Fitoterapia, 2001
Xylopia frutescens is a tree native to the Brazilian Amazon whose seeds are rich in kaurenoic acid, a diterpene that showed in vitro activity against Trypanosoma cruzi. Aiming to find out alternative sources for kaurenoic acid, the content of some kaurane diterpenes was evaluated in X. aromatica and X.
