The sesquiterpenoid composition in the root and the DNA sequences of evolutionarily neutral regions were studied in Ligularia anoleuca and Ligularia fischeri (Asteraceae) collected in the Sichuan Province of China. LC-MS analysis showed that L. anoleuca populations from different localities had different chemical compositions. However, the isolated compounds were similar to each other, indicating that the differences in chemical composition were not large. The DNA analysis suggested that the two species were indistinguishable. Seventeen furanoeremophilanes and an eremophilane acetal were isolated.
研究了中国四川省采集的橐吾属（菊科）植物无梗橐吾和尼泊尔橐吾的根中的倍半萜类成分和进化上中性区域的 DNA 序列。LC-MS 分析表明，来自不同地区的无梗橐吾种群具有不同的化学成分。然而，分离出的化合物彼此相似，表明化学成分的差异不大。DNA 分析表明，这两个物种无法区分。分离得到了 17 个呋喃埃里莫芬烷和一个埃里莫芬烷缩醛。
