Abstract: | Chemical investigation of Acanthus ilicifolius var. xiamenensis led to the isolation of eleven compounds, and their structures were identified to be 2-benzoxazolinone (1), 2-hydroxy-2H-1,4-benzoxazin-3(4H)-one (2), (2R)-2-O-β-d-glucopyranosyl-2H-1,4-benzox azin-3(4H)-one (3), (2R)-2-O-β-d-glucopyranosyl-4-hydroxy-2H-1,4-benzoxazin-3(4H)-one (4), (2R)-2-O-β-d-glucopyranosyl-7-hydroxy-2H-1,4-benzoxazin-3(4H)-one (5), lyoniside (6), 3′-methoxy-luteolin-7-O-β-d-glucopyranoside (7), β-sitosterol-3-O-β-d-glucopyranoside (8), stigmasterol octadecanoate (9), β-sitosterol octadecanoate (10), stigmasterol-3-O-β-d-glucopyranoside (11) on the basis of mass and NMR spectra. This is the first report on the occurrence of compound 6 and 7 in Acanthaceae. This work also represents the first phytochemical work on the roots of A. ilicifolius var. xiamenensis. |
