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 spectroscopic data analysis and compared with literature data. The antitumor activity was determined by MTT assay.
Ten compounds had been isolated and identified as(-)-magnocurarine( 1),N-methyl-laurotetanine( 2),laurotetanine( 3),( +)-boldine( 4),(-)-norisoboldine( 5),( +)-norisocorydine( 6),pmethane-3,8-trans-diol( 7),p-methane-3,8-cis-diol( 8),eudesm-4( 15)-ene-7,11-diol( 9) and 4β,6β-dihydroxy-1α,5β( H)-guai-9-ene( 10). Compounds 2 ~ 4 showed significant inhibitory activities against HT-29,SGC-7901,SMMC-7721 and A549 cells.
Compound 1,9 and 10 are isolated from this plant for the first time. The IC50 value of compound 2 against HT-29 and SGC-7901 cell lines is even lower than VP-16.
