Chemical Constituents of Ligularia Wilsoniana Collected in Chongqing, China

The chemical constituents of Ligularia wilsoniana were studied for the first time, using four samples collected in Chongqing City, China. Two new compounds, 6β-(2′,3′-epoxy-2′-methylpropanoyloxy)-1β,10β-epoxyfuranoeremophilane and 11αH-6β-(2′-hydroxymethylacryloyloxy)-1β,10β;7β,8β-diepoxyeremophilanolide, as well as eight known compounds, were isolated from one of the samples, while three to four known furanoeremophilanes were isolated from the...
