Ab. Pomilio et al., ANTITUMOR AND CYTOTOXIC SCREEN OF 5,6,7-TRISUBSTITUTED FLAVONES FROM GOMPHRENA-MARTIANA, Journal of ethnopharmacology, 44(1), 1994, pp. 25-33
An in vivo antitumor screening of extracts of Gomphrena martiana indic
ated positive activity in the petroleum ether extract, and its further
bioactivity-directed fractionation resulted in a lipophilic flavonoid
fraction. Upon inoculation of various doses of 5,6,7-trisubstituted f
lavones on two murine tumor lines, Sarcoma 180 and Ehrlich's carcinoma
, a decrease of tumor growth was observed. An in vitro KB cultured cel
l screen indicated cytotoxicity
