  • Title: An anti-estrogenic lignan glycoside, tracheloside, from seeds of Carthamus tinctorius.
    Author: Yoo HH, Park JH, Kwon SW.
    Journal: Biosci Biotechnol Biochem; 2006 Nov; 70(11):2783-5. PubMed ID: 17090940.
    Abstract:
    The lignan glycoside, tracheloside, was isolated from seeds of Carthamus tinctorius (Compositae) as an anti-estrogenic principle against cultured Ishikawa cells by employing a bioassay-linked HPLC-ELSD method. Tracheloside significantly decreased the activity of alkaline phosphatase (AP), an estrogen-inducible marker enzyme, with an IC(50) value of 0.31 microg/ml, a level of inhibition comparable to that of tamoxifen (IC(50) = 0.43 microg/ml).
