From the aerial parts of Salvia mexicana var. mexicana, two C-10 epimers (alpha and beta) of salvimexicanolide were isolated. Our interpretation of the data, especially the (13)C NMR, led us to conclude that the previously described (13)C-NMR spectrum of the a-epimer was not accurately assigned and it actually corresponds to the beta-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.
