M. Nieto et al., 8-HYDROXYSALVIARIN AND 7,8-DIDEHYDRORHYACOPHILINE, 2 NEW DITERPENES FROM SALVIA-REFLEXA, Journal of natural products, 59(9), 1996, pp. 880-882
From the leaves of Salvia reflexa the known neoclerodanes salviarin (1
) and 6 beta-hydroxysalviarin (2) have been isolated, together with tw
o new diterpenes, 15,16-epoxy-8 alpha-hydroxyneocleroda-2,13(16), 14-t
riene-17,12R:18,19-diolide (3), and the 5,6-secoclerodane, 7,8-didehyd
rorhyacophiline (5). The structures of 3 and 5 were deduced from their
spectroscopic data.
