Abstract
Anhydrous methanolic HCl has been found to be an excellent reagent for rele asing ellagic acid and gallic acid (as methyl gallate) from biomass substra tes. Optimization of both the reaction conditions and the gradient HPLC ana lysis has led to the development of a new protocol. The method provides ell agic acid yields significantly higher than those obtained previously, indic ating total ellagic acid contents of several substrates have previously bee n underestimated.
