摘要： A carnosic acid-rich plant extract can be produced by extracting a dried and comminuted plant material containing carnosic acid with supercritical CO
2 at a pressure of at least 200 bar and at a temperature of at most 100 °C. In a first step, supercritical CO
2
in a quantity of 10 to 50 kg of CO
2 per kg of plant material is passed through the plant material to obtain a first CO
2
extract. In a second step, additional supercritical CO
2
is passed through the plant material to obtain a second CO
2 extract, and a carnosic acid-rich plant extract is separated from the second CO
2 extract by lowering the pressure.

摘要： A process for producing cycloalkenamer-containing compositions involves converting at least one cycloalkene by ring-opening metathetic polymerization to obtain a polyalkenamer-containing product mixture. The product mixture is worked up to remove monomers and oligomers of the cycloalkenes to obtain the polyalkenamer-containing composition by extraction with CO2. The extraction involves at least two stages: an extraction with liquid CO2 under the supercritical conditions, and then an extraction with supercritical CO2. Such cycloalkenamer-containing compositions can be used, for example, in the field of packaging materials, especially for food and drink.
