Abstract
Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.
Claims18
A method of preparing a composition comprising monomers, oligomers, or both derived from cutin, the method comprising:
- combining cutin-containing plant matter with a solvent to yield a mixture, wherein the solvent comprises a nucleophilic solvent, and has a boiling point at a first temperature at a first pressure of one atmosphere;
- and
- increasing the temperature of the mixture to a second temperature and the pressure of the mixture to a second pressure to yield a composition comprising monomers, oligomers, or both derived from cutin, wherein the second temperature is greater than the first temperature and the second pressure is greater than one atmosphere, and wherein the monomers, oligomers, or both comprise esters.
A method of preparing a composition comprising monomers, oligomers, or both derived from cutin, the method comprising:
- combining cutin-containing plant matter with a solvent to yield a mixture, wherein the solvent comprises a nucleophilic solvent, and has a boiling point at a first temperature at a first pressure of one atmosphere;
- increasing the temperature of the mixture to a second temperature and the pressure of the mixture to a second pressure to yield a composition comprising monomers, oligomers, or both derived from cutin, wherein the second temperature is greater than the first temperature, the second pressure is greater than one atmosphere, and the monomers, oligomers, or both comprise esters;
- and
- chemically modifying at least some of the monomers, oligomers, or both.
