摘要

A new benzoxazinoid alkaloid, (2R)-2-O-(2′-methoxy-4′-carboxyphenyl)-2H-1,4-benzoxazin-3(4H)-one (1) was isolated from the extract of the whole plants of Acanthus ilicifolius var. xiamenensis, together with nine known compounds (210). The structure elucidations were based on analyses of spectroscopic and mass-spectrometric data, including 1D, 2D NMR, and HR-MS. All compounds were examined for their anti-inflammatory and cytotoxic activities. Compound 10 exhibited moderate cytotoxicity against the HeLa, HepG2, and KB cancer cell lines with IC50 values ranging from 14.71 to 31.07 μM.
