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

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.
