✦ Synopsis

The brassinosteroids brassinolide, castasterone and 24-epi-castasterone could be isolated and identified from seeds of Daucus carota. Furthermore, a new pregnanolone glucoside was identified as ␤-D-glucopyranosyl-(1→2)-␤-D-glucopyranosyl-3␤-hydroxy-5␣-pregnane-20-one (sophorosylpregnanolone) by nuclear magnetic resonance spectroscopy, liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry.

Carrots (Daucus carota L. var. Caro Pride) were extracted with supercritical fluid carbon dioxide (SFOC 2 ) under various combinations of pressures and solvent modifiers at 40°C and analysed for their ␣and ␤-carotene content by high pressure liquid chromatography. The SFCO 2 extraction at 40°C and 6
