Abstract

From the aerial parts of Salvia mexicana var. mexicana, two C-10 epimers (α and β) of salvimexicanolide were isolated. Our interpretation of the data, especially the 13C NMR, led us to conclude that the previously described 13C-NMR spectrum of the α-epimer was not accurately assigned and it actually corresponds to the β-epimer. The structures proposed for the salvimexicanolides were verified by means of NOESY experiments. Dugesin B, arbutin, naringenin and the mixture of oleanolic and ursolic acids were also isolated from this Salvia spp.

摘要

从墨西哥鼠尾草的地上部分分离得到两个 C-10 差向异构体（α 和 β）的 salvimexicanolide。我们对数据的解释，特别是 13C NMR，使我们得出结论，之前描述的 α-差向异构体的 13C-NMR 谱没有准确分配，它实际上对应于 β-差向异构体。通过 NOESY 实验验证了 salvimexicanolide 的结构。还从这种 Salvia spp 中分离得到了杜格斯因 B、熊果苷、柚皮素和齐墩果酸和熊果酸的混合物。
