Electrochemical behavior and determination of tumor inhibiting or promoting activities of flavonoids
Kozics K, Krajcovicova Z, Vachalkova A
Neoplasma
. 2006 Jul;
53(4):337-42.
PMID: 16830063
This paper deals with determination of the tumor inhibiting or promoting activities of 11 flavonoids performed by DC polarography. Flavonoids were tested in the presence of polyaromatic carcinogen 7,12-dimethylbenz(a)anthracene (DMBA)...
