title: Megastigmane, aliphatic alcohol and benzoxazinoid glycosides from Acanthus ebracteatus.
abstract: From the aerial part of Acanthus ebracteatus, a megastigmane glycoside (ebracteatoside A), three aliphatic alcohol glycosides (ebracteatosides B-D), as well as 7-chloro-(2R)-2-O-beta-D-glucopyranosyl-4-hydroxy-2H-1,4-benzoxazin-3(4H)-one (7-Cl-DIBOA-Glc) were isolated together with 22 known compounds. Structural elucidations were based on analyses of spectroscopic data.
