1. A method of preparing a composition from cutin-containing plant matter, comprising:
- obtaining cutin from the cutin-containing plant matter; and
decomposing the cutin to form compounds of Formula II, esters thereof, or compounds of Formula III, wherein the decomposing of the cutin comprises;
adding the cutin to a solvent to form a mixture, the solvent having a boiling point at a first temperature at a pressure of one atmosphere; and
heating the mixture to a second temperature and second pressure, the second temperature being higher than the first temperature and the second pressure being higher than one atmosphere; and
wherein Formula II and Formula III are;

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.
