title: Reversed-phase high-performance liquid chromatographic investigation of levodopa preparations II: Levodopa determination.
abstract: A reversed-phase high-performance liquid chromatographic procedure with UV detection at 280 nm is presented for levodopa determination in pharmaceutical preparations. The method is fast and specific for levodopa in the presence of its most likely impurities and degradation products.
