Phytochemical investigation on <i>Trichilia elegans</i> A. Juss (Meliaceae)

A phytochemical investigation of the leaves and stems of <i>Trichilia elegans</i> A. Juss resulted in the isolation and purification of twenty compounds, including three steroids (<b>1</b>–<b>3</b>), two coumarins (<b>4</b>,<b>5</b>), eleven phenolic acid derivatives (<b>6</b>–<b>16</b>), one oxazol derivative (<b>17</b>) and three glycosylated flavonoids (<b>18</b>–<b>20</b>). The structures of these compounds were elucidated through NMR spectroscopy and comparison with literature data. This study represents the first report of the natural occurrence of glycosylated flavonoids in <i>T. elegans</i> and the first description of compounds (<b>4</b>–<b>20</b>) in this species.
