CARVALHO, Mário G. de et al. Pimarane Diterpenes and a Sesquiterpene from Salzmmania nitida. An. Acad. Bras. Ciênc. [online]. 2006, vol.78, n.1, pp. 17-21. ISSN 1678-2690. http://dx.doi.org/10.1590/S0001-37652006000100003.
Two new terpenoids, (+)-3-oxo-thermarol and 11-acetoxyeudesman-4a-methyl-5a-ol along with the (+)- thermarol were isolated from the aerial parts of Salzmmania nitida. The structures and unambiguous 1H and 13C chemical shift assignments were established by spectroscopic means, including homo and heteronuclear techniques.
