A New Languidulane Diterpenoid from Salvia mexicana var. mexicana

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 (13)C NMR, led us to conclude that the previously described (13)C-NMR spectrum of the α-epimer was not accurately assigned and it actu...

Descripción
Sumario: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 (13)C NMR, led us to conclude that the previously described (13)C-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.
