The oncogenicity of chloroacetanilide herbicides (1-5) is proposed to involve bioactivation to 2,6-dialkylbenzoquinonimines (quinonimines, 9) based on two earlier observations: (1) in vitro conversion of the alachlor (1) metabolite diethylaniline (7E

Three new diterpenes have been isolated from Eremophila macmillania , E. falcata and E. ‘flaccida’ . In contrast to other Eremophila species the leaf resin of E. ‘flaccida’ is composed of flavanones and the sesquiterpene β-eudesmol.
