A new sesquiterpene from <i>Ixeris chinensis</i>

<div><p>The petroleum ether (PE) extract from <i>Ixeris chinensis</i> was submitted to chromatographic separation. A new sesquiterpene, namely 14-noreudesma-3-hydroxy-3-en-2,9-dione, was isolated from the PE extract. The structures of the sesquiterpene was elucidated by using spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.</p></div

A biflavonoid glycoside from <i>Lomatogonium carinthiacum</i> (Wulf) Reichb

<div><p>A biflavonoid glycoside with a new carbon skeleton, named carinoside A, was isolated from the <i>n</i>-BuOH crude extract of the whole plant of <i>Lomatogonium carinthiacum</i> (Wulf) Reichb. The structure of the new compound was elucidated by using spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.</p></div
