title: Terpenoids from the medicinal plant Maytenus ilicifolia.
abstract: Four new terpenoids (1-4) were isolated from the root bark of Maytenus ilicifolia. Their structures were determined by spectroscopic studies, and complete 1H and 13C NMR assignments were achieved by 2D NMR spectroscopy. We also report an efficient method for the separation of quinonemethide triterpenes based on centrifugal partition chromatography.
