Objective: To investigate the chemical constituents from the flowers of Carthamus tinctorius.
Method: 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.
Result: 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.
Conclusion: Two compounds (II and III) were obtained from the genus of Carthamus for the first time.
