Description

Four Ligularia species, L. kanaitzensis, L. vellerea, L. subspicata, and L. lamarum collected in Yunnan province of China were examined and 64 compounds were isolated. Compounds 1-15 were new. The samples of L. kanaitzensis could be divided into two groups, based on chemical composition of the root extract. Furanoeremophilane-6β,10β-diol and its derivatives were isolated from one group, while eremophilan-8-one derivatives were isolated from the other group. In contrast, intra-specific diversity was found to be small in the atpB-rbcL intergenic sequence. The samples of L. vellerea could be divided into three groups. The major components isolated from types A, B, and C were 6,15-dioxygenated furanoeremophilanes, 1,6-dioxygenated furanoeremophilanes, and 6,15-dioxygenated eremophilanolides. The difference in chemical composition is consistent with geographic distribution. Intra-specific diversity in the atpB-rbcL sequence was small. The samples of L. subspicata were grouped into two, that is, a group A producing 1-angeloyloxy derivatives and a group B producing ligularol (35) and its derivatives. Diversity was found to be present in the nucleotide sequences as well. 1,10-Dioxygenated derivatives from L. lamarum were isolated. The chemical composition was diverse. However, the DNA sequence of atpB-rbcL is currently under investigation.
