title: Constituents of Ligularia brassicoides Collected in China: A New Diels-Alder Adduct of Eremophilan-10β-ol and Methacrylic Acid.
abstract: Chemical study of four samples of Ligularia brassicoides collected in Sichuan Province of China afforded 18 compounds, five of which were new. LC-MS profiles were somehow similar to each other, although the compound ratio was slightly different. One of the new compound was a Diels-Alder adduct between franoeremophilan-10β-ol and methacrylic acid.
