Abstract

<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="metricconverter"> A new coumarin diol has been isolated along with three known coumarin compounds, 6,8-diprenylumbelliferone, bergapten and isopimpinellin from the chloroform fraction of the leaves of the plant,<b> </b><i>Chloroxylon swietenia</i> DC<b>. </b>The structure of new compound has been established as 6-(2′,3′-dihydroxy-3-methylbutyl)-8-prenylumbelliferone based on the spectral (UV, IR, ¹H, ¹³C and 2D NMR and mass) data. </smarttagtype>
