Popis:	Two new crystalline guaianolides,viz., rhaposerine and rhaserolide, were isolated from an ethanolic extract of the above-ground part of the plantRhaponticum serratuloides by column chromatography along with sesquiterpene lactones,viz., centaurepensin and acroptilin, which have been found in other plants. The chemical structures of the title lactones were established by1H and13C NMR spectroscopy and 2D1H−1H (COSY) and13C−1H (COSY and COLOC) NMR spectroscopy.
