Studies of the mutagenicity and antimutagenicity of hispidulin and hortensin, the flavonoids from Millingtonia hortensis L. (Bignoniaceae), were performed using the liquid preincubation method of the Salmonella/microsome test. At the highest dose tested, 100 [mu]g/plate, both compounds showed no mutagenicity and no cytotoxicity toward S. typhimurium strains TA98 and TA100 either in the presence or absence of S9 mix. However, these substances were antimutagens toward 2-aminoanthracene, aflatoxin B1 (in TA98), and dimethylnitrosamine (in TA100); but neither substance inhibited the direct mutagenic activity of 2-(2-furyl)-3-(5-nitro-2-furyl) acrylamide nor that of sodium azide in strains TA98 and TA100, respectively. 22 refs., 4 figs., 2 tab.
