Limonoid from the rhizomes of <i>Luvunga scandens</i> (Roxb.) Buch. Ham

For first time, the chemical constituents of the rhizomes of <i>Luvunga scandens</i> (Roxb.) Buch. Ham. were investigated and led to the isolation of one new limonoid named Luvunga A (<b>1</b>), together with seven known compounds, including one limonoid (<b>2</b>) and six coumarins (<b>3</b>–<b>8</b>) were isolated for the first time from the species <i>L. scandens</i> by various chromatography methods. Their chemical structures were elucidated by IR, UV, HR-ESI-MS, NMR 1D and 2D experiments and compared with literatures.
