Microscale thioacidolysis method for the rapid analysis of β-O-4 substructures in lignin

Abstract

Thioacidolysis is a method to detect the β-O-4 substructures of lignin, and has been employed as a diagnostic test for the presence of lignin. However, the conventional thioacidolysis protocol is low-throughput and is a bottleneck in the characterization of lignins in a large number of samples such as transgenic lines. Recently, a rapid analysis protocol for thioacidolysis was reported. In this study, we modified mainly the work-up process. Our microscale protocol showed higher yields of thioacidolysis products than the conventional protocol.
