Chemical and Genetic Diversity of Ligularia latihastata and Ligularia villosa in Yunnan Province of China

The chemical constituents of the root extracts and the nucleotide sequences of the atpB‐rbcL intergenic region of Ligularia latihastata and L. villosa , collected in northwestern Yunnan Province, were studied. In the twelve collected samples of L. latihastata , two major benzofurans, 5,6‐dimethoxy‐2‐(1‐methylethenyl)‐1‐benzofuran ( 1 ) and euparin ( 2 ) were detected as major components. The minor compound (2 R* ,3 S*...
