Determination of the Cytotoxicity of Rumex crispus during the Vegetation Period Using a Brine Shrimp Bioassay

Abstract

The percentage of anthraquinone glycosides in the roots of Rumex crispus L. (Polygonaceae) is significantly greater than in other parts of the plant. The roots of R. crispus in different vegetation stages were investigated with regard to anthraquinone glycoside content. Their toxicity towards shrimp were also tested during the vegetation period. The data showed that the percentage of anthraquinone glycosides as well as the toxic effect on the shrimp increased during the vegetation period. © 1995, Verlag der Zeitschrift für Naturforschung.
