Abstrakt
From sugarcane juice, a flavone, identified by spectroscopic methods as tricin-7-O-beta-(6''-methoxycinnamic)-glucoside, was isolated, in addition to orientin. The tricin derivative was shown to have antioxidant activity higher than Trolox by means of the DPPH assay and lower by the beta-carotene/linoleic acid system. It showed in vitro antiproliferative activity against several human cancer cell lines, with higher selectivity toward cells of the breast resistant NIC/ADR line.
