[Studies on chemical constituents from the flowers of Carthamus tinctorius L].

To investigate the chemical constituents from the flowers of Carthamus tinctorius.The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral analysis.Eight compounds were identifed as palmitic acid (I), 1-O-hexadecanolenin (II), trans-3-tridecene-5,7,9,11-tetrayne-1,2-diol (III), trans-trans-3,11-tridecadiene -5,7,9-triyne -1,2-diol (IV), coumaric acid (V), daucosterol (VI), apigenin (VIl) and kaempferol (VIII), respectively.Two compounds (II and III) were obtained from the genus of Carthamus for the first time.
