Objective: 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.
Methods: The constituents were isolated by column chromatography such as RP-18,Sephadex LH-20 and silica gel,and their structures were elucidated by spectroscopic data analysis and compared with literature data. The antitumor activity was determined by MTT assay.
