Abstract
Two new additional trijugin-type limonoids, sandrapins D (4) and E (5), which are analogues of the previously reported sandrapins A-C (1-3), were isolated as minor components from the leaves of Sandoricum koetjape (Meliaceae), and their structures were elucidated on the basis of MS and NMR spectral data.
