Structure elucidation and complete NMR spectral assignments of a new benzoxazolinone glucoside from Acanthus ilicifolius.
A new benzoxazolinone glucoside, 4-O-beta-D-glucopyranosyl-benzoxazolin-2(3H)-one, was isolated from Acanthus ilicifolius, a medicinal plant from south China. The complete (1)H and (13)C NMR assignments of the compound were carried out by using DEPT, HMBC, HMQC, NOESY and (1)H--(1)H COSY spectra.
