Abstract
Three novel compounds, two alkaloids [2-ethoxycarbonyltetrahydroharman] and 6-hydroxy-2-methyltetrahydroharman and a diterpene [12-hydroxy-13-methyl-1,8,11,13-podocarpatetraen-3-one], together with other known substances were isolated from Croton moritibensis. Their structures were established by spectroscopic methods, including 2D NMR techniques.
