Pimarane Diterpenes and a Sesquiterpene from Salzmmania nitida

Two new terpenoids, (+)-3-oxo-thermarol and 11-acetoxyeudesman-4alpha-methyl-5alpha-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.
