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
OBJECTIVE
To study the alkaloid constituents of the root of Lindera angustifolia Cheng.
METHODS
The constituents were isolated and purified by column chromatography and the structures were characterized by spectral analysis.
RESULTS
Seven aporphine alkaloids, laurotetanine (I), N-methyllaurotetanine
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
