Abstract: Two methods, namely: n-butyl alcohol-hydrochloric acid method and vanillin-hydrochloric acid method, were used to determine the oligomeric proanthocyanidins (OPC) content in larch bark extracts. The two methods were compared and analyzed according to the reaction principles. As a result, the vanillin-hydrochloric acid method was favourable to meet the strict requirement of quality control.

Key words: oligomeric proanthocyanidins, larch
