Abstract: Eleven compounds were isolated from the aerial parts of Psammosilene tunicoides by means of column chromatography.Their structures were identified as maltol (1),nicotinamide (2),uridine (3),deoxyuridine (4),thymidine (5),deoxythymidine (6),uracil (7),1-O-(4-hydroxymethylphenyl) -α-L-Rhamnopyranoside (8),benzyl-β-D-glucopyRanoside (9),(6R,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranoside (10) and capitasterone (11),respectively.All compounds were isolated from P.tunicoides for the first time.

Key words: Psammosilene tunicoides, aerial parts, chemical constituents
