✦ Synopsis

Chemical and genetic study of Ligularia anoleuca and L. veitchiana, which belong to section Ligularia, series Speciosae, was carried out. From L. anoleuca samples, collected in Yunnan and Sichuan Provinces of China, a new compound, furanoeremophil-1(10)-en-6a-ol, was isolated together with known 6b-{[2-(hydroxymethyl)prop-2-enoyl]oxy}furanoeremophil-1(10)-ene and 1b,10b-epoxy-6b-{[2-(hydroxymethyl)prop-2-enoyl]oxy}furanoeremophilane. From L. veitchiana samples, collected in Yunnan Province, euparin, 2-isopropenyl-5,6-dimethoxybenzofuran, and 6-hydroxy-3b-methoxytrementone were isolated. DNA Sequencing of the internal transcribed spacers of the ribosomal RNA gene showed that the two species are not particularly close despite morphological similarities, in agreement with the chemical results.
