1. A process for isolating lignin from tobacco biomass, the process comprising:
(a) contacting a quantity of tobacco biomass with a quantity of acid to form an acidified digest mixture; (b) contacting a quantity of the acidified digest mixture with a quantity of butanol to form a butanol-containing mixture; (c) effecting a separation of a quantity of the butanol-containing mixture into a butanol-soluble phase and a butanol-insoluble phase; and (d) effecting a removal of butanol from a quantity of the butanol-soluble phase sufficient to yield a quantity of an isolated lignin from the butanol-soluble phase.
