CRISPANE AND CRISPANONE, 2 COMPOUNDS FROM PETROSELINUM-CRISPUM WITH A NEW CARBON SKELETON

The analysis of parsley revealed the presence of two novel compounds, C20H30O4 and C20H32O3. They were isolated and purified by means of high speed counter-current chromatography and their structures were elucidated by spectroscopic methods and some chemical transformations. Their systematic names according to the chemical abstract nomenclature are:[1S-[1-alpha,2-beta(Z),4a-alpha,8a-beta]]-[1,2,4a,5,6,7,8,8a-octahydro-1-hydroxy-4,4a-dimethyl-1-(1-methylethyl)-7-oxo-2-naphthalenyl]-2-methyl-2-butenoate for compound 1 and [1S-[1-alpha,2-beta(Z),4a-alpha,8a-beta]]-[1,2,4a,5,6,7,8,8a-octahydro-1-hydroxy-4,4a-dimethyl-1-(1-methylethyl)-2-naphthalenyl]-2-methyl-2-butenoate for [1,2,4a,5,6,7,8,8a-octahydro-1-hydroxy-4,4a-dimethyl-1-(1-methylethyl)-2-naphthalenyl]-2-methyl-2-butenoate for compound 2. The trivial names crispanone and crispane, respectively are proposed.
