Abstract:
OBJECTIVETo isolate and identify the active xanthone glycosides in Halenia elliptica.
METHODThe compounds were isolated by column chromatography, semi-preparative high performance liquid chromatography and related techniques. Their structures were elucidated through spectroscopic analysis (NMR and MS).
RESULTSix xanthone glycosides were isolated and identified as: 2,3,5-trimethoxy-1-O-primeverosyloxyxanthone (1), 2, 3, 4, 5-tetramethoxy-1-O-primeverosyloxyxanthone (2), 2, 3, 5, 7-tetramethoxy-1-O-primeverosyloxyxanthone (3), 2, 3, 7-trimethoxy-1-O-primeverosyloxyxanthone (4), 2, 3, 4, 7-tetramethoxy-1-O-primeverosyloxyxanthone (5), and 2, 3, 4, 5, 7-pentamethoxy-1-O-primeverosyloxyxanthone (6).
CONCLUSIONCompounds 4-6 were isolated from this plant for the first time.
