The invention concerns the use of 2E,4E-decadienoic acid-N-isobutylamide (trans-pellitorin) as flavorant, in particular as salivation inducing flavor substance, preferably in a foodstuff or nutrient, an oral hygienic preparation or a gourmet or snack preparation. Further, the invention concerns preparations, semi-finished preparations as well as fragrance, aroma and taste compositions, containing trans-pelletorin as well as a processes for the production of trans-pelletorin.

Use of trans-pellitorin as flavor substance

There are provided new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I)

3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives

The invention relates to new furfurylthioalkanes of the formula ##STR1## wherein n can be zero or 1

Furfurylthioalkanes, a process for their preparation and their use

5-Z-octenyl esters of the formula ##STR1## in which R represents hydrogen, methyl or ethyl, have an intensive mango aroma, so that the compounds I can be added to fruit compositions and aroma compositions; they have flavor-intensifying and flavor-rounding action.

5-Z-octenyl esters, process for their preparation and their use

Compounds of the formulae ##STR1## in which R is hydrogen or methyl, and the dashed lines represent an additional bond in the 11- or 12-position, have extraordinary olfactory properties.

Macrocyclic lactones as musk fragrance enhancers

Use of 3-acylthiohexyl esters of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.5 -C.sub.12 -aryl, including furyl and thienyl, as aroma and/or odoriferous substances, and aroma and odoriferous substance compositions containing these compounds.

Use of 3-acylthiohexyl esters as aroma and odoriferous substances

New 3-arylpyrrolidine-2,4-dione derivatives of the formula (I): ##STR1## in which the variables A, B, E, R, X, Y, Z and n are set forth in the specification, are useful as insecticides, acaricides, and herbicides.

3-aryl-pyrrolidine-2,4-dione derivatives

There are provided new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) ##STR1## in which A and B are identical or different and independently of one another in each case represent hydrogen, alkyl, alkenyl, alkynyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aryl or

There are provided an aryl carboxylic acid derivatives of the formula (XVIa) ##STR1## Aryl carboxylic acid derivatives of the formula (XVIa) have a particularly pronounced activity against animal pests, in particular against insects and arachnids, and against weeds.

Aryl carboxylic acid derivatives

There are provided new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) ##STR1## The new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) have a particularly pronounced activity against animal pests, in particular against insects and arachnids, and against weeds.

Thioalkane .alpha.,.beta.-diketones have interesting organoleptic properties and are therefore suitable as aroma substances.

Use of thioalkanediones as aroma substances

There are provided new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) ##STR1## in which A and B are identical or different and independently of one another in each case represent hydrogen, alkyl, alkenyl, alkynyl, alkoxyalkyl, alkythioalkyl, cycloalkyl or optionally substituted aryl or

3-hydroxy-4-aryl-5-oxo-pyrozoline derivatives, compositions and use

Ketals, preferably glycerol ketals such as, for example, 1-menthone glycerol ketal or 3,3,5-trimethylcyclohexanone glycerol ketal, have a physiological cooling effect and are therefore suitable as active compounds in compositions which are intended to cause a sensation of freshness on human skin or mucous membrane.
