title: Diversity in Chemical Constituents of Ligularia longihastata Collected in China.
abstract: Root constituents of Ligularia longihastata were examined for the first time. Fourteen eremophilane sesquiterpenes, including two new eremophilanes identified as 3α-isobutyroyloxy-7βH-eremophila-9,11-dien-8-one and 3β-angeloyloxy-1β,10β-epoxyfuranoeremophilan-9-one, and three eudesmanes were isolated. From samples collected in Baiyu County, Sichuan Province, furanoeremophilane derivatives were isolated, while various eremophilan-8-ones were isolated from samples collected in Kangding County, Sichuan. The results suggest chemical diversity in the species.
