title: Triterpenoids and a lignan from the aerial parts of Maytenus apurimacensis.
abstract: Five new triterpenes (1-5) and one new lignan (6) were isolated from the aerial parts of Maytenus apurimacensis. Their structures were determined on the basis of spectroscopic studies, including homonuclear and heteronuclear correlation NMR experiments (COSY, ROESY, HSQC, and HMBC).
