Methanolic extracts of 11 Rumex L. species (Polygonaceae) were examined against brine shrimp and R. scutatus L. has shown significant brine shrimp lethality (LC5O=0.96 |a,g/ml). Methanolic extracts of the roots of R. scutatus were fractionated and the active fraction led to the isolation of 4 anthraquinone aglycones: emodin, chrysophanol, physcion and aloe emodin. Their toxic sequence was found...
