OBJECTIVE
To study the anti-tumor metastatic constituents from Lindera glauca.
METHODS
Constituent isolation and purification was carried by repeated column chromatography (silica gel, Toyopearl HW-40 and preparative HPLC). Their structures were elucidated on the basis of spectral data analysis. The
To study the chemical constitutes from the roots of Lindera glauca and the alkaloids influence on proliferation of HT-29,SGC-7901,SMMC-7721 and A549 cell lines.
The constituents were isolated by column chromatography such as RP-18,Sephadex LH-20 and silica gel,and their structures were elucidated by
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,
Eight alkaloids, including a new compound, (+)-norboldine acetate (1), and seven known ones, (+)-norboldine (2), (+)-boldine (3), (+)-laurotetanine (4), (+)-N-methyllaurotetanine (5), (+)-reticuline (6), (-)-pronuciferine (7), and pallidine (8) were isolated from the roots of Lindera aggregata. The
