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
The bark of Magnolia officinalis is a well-known Traditional Chinese Medicine. In the present study, two new alkaloids, named (S)-4-keto-magnoflorine (6) and (R)-3,4-dehydromagnocurarine (11), together with seven known alkaloids: (S)-magnoflorine (5), trans/cis N-feruloylputrescine (7/8),
