Popis:	The germacrane-type sesquiterpene lactones tatridin A and B were isolated for the first time during chemical studies of the extract of Lepidolopha karatavica. The structures of the compounds were elucidated using spectral data and X-ray crystal structure analyses (XSAs). Correlations of the XSAs and CD spectra defined the absolute configurations of the molecules. Possible conformational states of 3,8-deoxytatridin A and B were calculated by a quantum chemical method.
