From the aerial parts of Calceolaria filicaulis ssp luxurians, two new diterpenes, 13,18-dihydroxy-thyrsiflorane and 13-isovaleroyl-18- hydroxythyrsiflorane were isolated, purified and identified as their acetylderivatives, besides the β-sitosterol. Their structures were determined by spectroscopic means. © 2007 Sociedad Chilena de Química.
