Chemical constituents from rhizomes of <i>Cautleya spicata</i> (Sm.) Baker (Zingiberaceae)

<p>The chemical investigation of ethanolic extract from rhizomes of <i>Cautleya spicata</i> (Sm.) Baker (Zingiberaceae) has resulted in the isolation of eight compounds which were characterised as β-sitosterol (<b>1</b>), β-sitosterol β-D-glucoside (<b>2</b>), bergapten (<b>3</b>), zerumin A (<b>4</b>), (E)-labda-8(17),12-diene-15,16-dial (<b>5</b>), kaempferol (<b>6</b>), quercetin (<b>7</b>) and astragalin (<b>8</b>). All compounds were identified by spectroscopic and chemical methods. This paper describes the first phytochemical work on <i>C. spicata</i>.</p
