RESUMO
Three new limonoids, named haperforins C2 (1), F (2), and G (3), were isolated from a sample of Harrisonia perforata leaves collected in Central Vietnam. Their structures were determined by single-crystal X-ray diffraction analyses, and their NMR and mass spectral data are reported.

RESUMO
Two new rearranged limonoids, named haperforine A (1) and haperforine E (2), were isolated from a sample of Harrisonia perforata leaves collected in Center Vietnam and their structures determined by X-ray diffraction analysis. The structure of a minor compound was established as 12-desacetylhaperforine A (3) by chemical correlation. Their NMR and mass spectroscopic properties are reported.
