title: NMR study of seven coumarins from mammea siamensis.
abstract: Seven known mammea coumarins, mammea A/AA cyclo D ( 1 ), mammea A/AD cyclo D ( 2 ), mammea A/AB cyclo D ( 3 ), mammea A/AC cyclo F ( 4 ), mam-mea A/AB cyclo F ( 5 ), mammea A/AA cyclo F ( 6 ), mammea B/AC cyclo F ( 7 ), were isolated for the first time from the hexane extract of Mammea siamensis . A detailed analysis of both 1D and 2D NMR spectral data of these compounds was made.
