从药用蒲公英（Taraxacum officinale）的根中分离得到5个吉马烷型和愈创木烷型倍半萜内酯，包括2个蒲公英酸衍生物，以及苄基葡萄糖苷、二氢松柏素、双氢另外三种内酯被鉴定为11 β，13-二氢lactucin，ixerin D和ainslioside。此外，还对二氢蒲公英酸的C-11位进行了立体化学归属。(C)2000 Elsevier Science B. V.保留所有权利。
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 11 beta, 13-dihydrolactucin, ixerin D and ainslioside. Moreover, the stereochemistry at C-11 in dihydrotaraxinic acid was assigned.
