1. A method for extracting organic compounds from lignocellulosic biomass comprising:
a. providing the lignocellulosic biomass to a reaction vessel;
b. contacting the lignocellulosic biomass in the reaction vessel with a first solvent comprising a C5-C20 nonpolar solvent, and a second solvent comprising a mixture of a C1-C10 organic solvent and water, wherein the first solvent and the second solvent are immiscible with one another;
c. mixing the first solvent and the second solvent with the lignocellulosic biomass in the reaction vessel sufficient to provide a solvent-lignocellulosic biomass mixture;
d. forming a three-phase system from the solvent-lignocellulosic biomass mixture, the three-phase system comprising:
i. a first phase comprising a lipid-rich phase comprising a lipid fraction and the first solvent;
ii. a second phase comprising a polyphenol-rich phase comprising a polyphenol fraction and the second solvent;
iii. a third phase comprising solid lignocellulosic biomass substantially free of the lipid fraction and the polyphenol fraction;
e. isolating the first phase and removing the first solvent from the lipid-rich phase to produce the lipid fraction; and
f. isolating the second phase and removing the second solvent from the polyphenol-rich phase to produce the polyphenol fraction.
