Plants constitute a source of novel phytotoxic compounds to be explored in searching for effective and environmentally safe herbicides. From previous screening plant extracts their phytotoxicity, dichloromethane extract Ammi visnaga (L.) Lam. was selected further study. Phytotoxicity-guided fractionation this yielded two furanochromones, khellin visnagin, which herbicidal activity had not been described before. Khellin visnagin were model species lettuce (Lactuca sativa) duckweed (Lemna...
Abstract During the past 30 yr an impasse has developed in discovery and commercialization of synthetic herbicides with new molecular targets novel chemistries. Similarly, there been little success bioherbicides, both microbial chemical. These bioherbicides are needed to combat fast-growing herbicide resistance fulfill need for more environmentally toxicologically safe herbicides. In response this substantial growing opportunity, numerous start-up companies utilizing approaches provide tools...
Khellin and visnagin furanochromones were recently reported as potential new bioherbicides with phytotoxic activities comparable to those of some commercially available herbicides. In this study, we examined the effect O-alkylation O-arylalkylation both khellin on its herbicidal antifungal activity. Synthetic analogues included O-demethyl visnagin, acetylated O-benzylated demethyl four alkylated analogues, six many which are here for first time. Both acetate indicated more activity...
