【 摘 要 】

Two novel sesquiterpene lactones were isolated from crude extract of the Eremanthus seidelii leaves. Reliable structural elucidations to these lactones were established by 1D and 2D NMR spectroscopic techniques and high-resolution electrospray mass spectrometry data. (C) 2012 Elsevier Ltd.
