  Five germacrane- and guaiane-type sesquiterpene lactones, including two previously described taraxinic acid derivatives, were isolated from the roots of Taraxacum officinale, together with benzyl glucoside, dihydroconiferin, syringin and dihydrosyringin. The other three lactones were identified as 11β, 13-dihydrolactucin, ixerin D and ainslioside. Moreover, the stereochemistry at C-11 in dihydrotaraxinic acid was assigned.

  Chromatographic separation of ethanolic root extracts of Taraxacum laevigatum and Taraxacum disseminatum afforded a total of eight germacrane- and eudesmane-type sesquiterpenoids, including new compounds, 1β,3β,6α-trihydroxy-4α(15)-dihydrocostic acid methyl ester and its 1-O-β-glucopyranoside. Their structures were established by spectroscopic analyses. In addition, the structure of 4α(15),11β(13)-tetrahydroridentin B-1-O-β-glucopyranoside was elucidated by extensive NMR studies.
