 Title    Concentrations of Anthraquinone Glycosides of Rumex crispus during Different Vegetation Stages  
 Abstract    The anthraquinone glycoside contents of various parts of Rumex crispus L. (Polygonaceae) in different vegetation stages were investigated by thin layer chromatographic and spectro-photometric methods. The data showed that the percentage o f anthraquinone glycoside in all parts of plant increased at each stage. Anthraquinone glycoside content was increased in leaf, stem, fruit and root from 0.05 to 0.40%. from 0.03 to 0.46%. from 0.08 to 0.34%, and from 0.35 to 0.91% respectively. From the roots of R. crispus, em odin-8-glucoside, RGA (isolated in our laboratory, its structure was not elucidated), traceable amount of glucofran-gulin B and an unknown glycoside (R f = 0.28 in ethyl acetate:m ethanol:w ater/100:20:10) was detected in which the concentration was increased from May to August. The other parts of plant contained only emodin-8-glucoside.
