A new sesquiterpenoid from <i>Scaphium macropodum</i> (Miq.) Beumee
<div><p>A new sesquiterpenoid, malayscaphiol (<b>1</b>), and three known compounds, lupeol (<b>2</b>), lupenone (<b>3</b>) and stigmasterol (<b>4</b>), were isolated from the methanolic extract of the stem bark of <i>Scaphium macropodum</i>. The structures of the isolated compounds were determined using several spectroscopic methods, including UV–vis, FT-IR, 1D and 2D NMR, and mass spectrometer. Major isolated compounds were assayed for cytotoxicity and anti-acetylcholinesterase activities. The chemotaxonomy significance of this plant was also discussed.</p></div
A new triterpenoid from <i>Sapium baccatum</i> (Euphorbiaceae)
<div><p>A new triterpene, malaytaraxerate (<b>1</b>), and four known compounds, taraxerol (<b>2</b>), taraxerone (<b>3</b>), docosyl isoferulate (<b>4</b>) and docosanoic acid 2′,3′-dihydroxypropyl ester (<b>5</b>), were isolated from the acetone extract of <i>Sapium baccatum</i> stem bark. The structures of the isolated compounds were determined using several spectroscopic methods, including UV–Vis, FT-IR, 1D and 2D NMR, and mass spectrometry. Major isolated compounds were assayed for cytotoxicity. The chemotaxonomic significance of this plant was also studied.</p></div
