Suttajit 1993 . Xili 1992 . Procinska 1991 . Aze 1991 . Ames test may be explained by genetic difference in the Salmonella strains used Matsui 1989 .
Salmonella assay while iso-steviol is inactive.
Respiration increased with up to 0.5 mM but decreased with higher concentrations Kelmer Bracht 1985 . Steviol, isosteviol and glucosilsteviol decreased glucose production and inhibited oxygen uptake in rat renal cortical tubules while stevioside was inactive Yamamoto 1985 . Hagiwara 1984 . Application of glycyrrhetinic acid or steviol to mouse skin 1 h before or after TPA decreased TPA-induced ornithine decarboxylase activity. Alone, they have no effect on ODC Okamoto 1983 .
