	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.

	Title	A Chemical Investigation of Pueraria mirifica Roots
	Abstract	Ten isoflavonoids including daidzein, daidzin (daidzein-7-O-glucoside), puerarin (daidzein-8-C-glucoside), genistein and coumestrol have been isolated from a methanolic extract of Pueraria mirifica roots. Apart from these known compounds and mirificin, a novel apioside derivative of puerarin, the roots have also been found to contain three minor coumestans and one 5-deoxyiso-flavone for which only limited spectroscopic data are currently available.

	Title	Glycosilation of Terpenols and Aromatic Alcohols by Cell Suspension Cultures of Peppermint (Mentha piperita L.)
	Abstract	Plant cell cultures effectively convert terpenoid and aromatic alcohols into glycosides. A quan-titative comparison showed a culture of peppermint (Mentha piperita) to be the most active among four species examined. The synthesis of glycosides was affected by the concentration of substrate, incubation period, cell age and aggregation, and by light. Conversion rates of exogenous alcohols were greater than 70% under optimized conditions.
