A new naphthoquinone and other antibacterial constituents from the roots of Xanthium sibiricum

Listed in DataCite

Reinvestigating the chemical constituents of the roots of Xanthium sibiricum led to the isolation of a new naphthoquinone ( 1 ), together with 13 known compounds ( 2 – 14 ).

Description

Their structures were elucidated by using spectroscopic analyses, including HR-ESI-MS, 1D and 2D NMR, and by comparing their NMR data with those of related compounds. Compound 1 showed moderate antibacterial activity against Escherichia coli , Bacillus subtilis , Micrococcus tetragenus and Staphylococcus aureus , while 6 and 12 showed stronger antibacterial activity than the positive control ciprofloxacin against E. coli , with minimum inhibitory concentration values of 0.17 and 0.35 μg/mL, respectively.
