Acylated flavanone glycosides fromRicinus communis

Naringenin 7-O-(6-O-p-coumaroly--D-glucopyranoside) and the new flavanone naringenin 7-O-(2-O-p-coumaroyl--D-glucopyranoside) have been isolated from the seeds of Ricinus communis L. The structures of the compounds isolated were established on the basis of the results of chemical transformations and spectral characteristics.Institute of Chemistry of Plant Substances, Academy of Sciences of the Uzbekistan Republic, Tashkent.
