Abstract
Five new triterpenes, one 17,14-friedolanostane (garcihombronane F, 1), three 17,13-friedolanostanes (garcihombronanes G-I, 2-4), and one lanostane (garcihombronane J, 5), were isolated from the leaves of Garcinia hombroniana together with nine known compounds including five triterpenes, two ionone-derived glycosides, and two flavonoid glucosides. Their structures were identified by analysis of spectroscopic data and comparison of the NMR data with those previously reported.
