title: Chemical constituents of Ligularia nelumbifolia and L. subspicata hybrid collected in Shangrila County, Yunnan Province of China.
abstract: Four Ligularia individuals possessing morphological characters of both L. nelumbifolia and L. subspicata were discovered in Shangrila County, Yunnan Province, China. DNA sequencing showed that the specimens were hybrids of the two species and their maternal parent was L. subspicata. The chemical composition of the root extract was examined for three of them as well as L. nelumbifolia and L. subspicata collected sympatrically. Nelumol was isolated from L. nelumbifolia, and furanoeremophilanes from L. subspicata. 1hile nelumol and furanoeremophilanes were detected in two of the hybrid samples, only furanoeremophilanes were detected in the others.
