OBJECTIVETo study the chemical constituents of Arenaria kansuensis.

METHODColumn chromatographic techniques were applied to isolated constituents. A combination of physico-chemical properties and spectroscopic analysis were used to identify structures of constituents.

RESULTFive compounds were obtained and elucidated as tricin (1), tricin-7-O-beta-D-glucopyranoside (2), tricin 4'-O-beta-guaiacylglyceryl ether (3), isoscoparin (4) and isovitexin (5).

CONCLUSIONCompound 2, 3 and 5 were isolated from A. kansuensis for the first time, compound 3 was obtained from the family Caryophyllaceae for the first time.
