• From the aerial parts of Calceolaria filicaulis ssp luxurians, two new diterpenes, 13,18-dihydroxy-thyrsiflorane and 13-isovaleroyl-18-hydroxy-thyrsiflorane were isolated, purified and identified as their acetylderivatives, besides the ß-sitosterol. Their structures were determined by spectroscopic means
