From the leaves of Hyptis salzmanii a new isopimarane diterpene, named (-)-salzol, and the new 4,2′,6′-trihydroxy-4′-methox,ychalcone were isolated, together with three known lignans, i.e. (+)-sesamin, (-)-cubebins, (-)-hinokinin, three known flavanones, i.e. (-)-isosakuranetin, (±)-sakuranetin, (+)-naringenin-7,4′-dimethylether, and p-methoxycinnamic acid. The structure of 20-benzoyloxy-6β,7β,8β,9α-tetrahydroxyisopimar-15-ene, assigned to (-)-salzol, and the structure of the chalcone were determined on the basis of chemical and spectral data

Abstract
From the leaves of Hyptis salzmanii a new isopimarane diterpene, named (-)-salzol, and the new 4,2′,6′-trihydroxy-4′-methox,ychalcone were isolated, together with three known lignans, i.e. (+)-sesamin, (-)-cubebins, (-)-hinokinin, three known flavanones, i.e. (-)-isosakuranetin, (±)-sakuranetin, (+)-naringenin-7,4′-dimethylether, and p-methoxycinnamic acid. The structure of 20-benzoyloxy-6β,7β,8β,9α-tetrahydroxyisopimar-15-ene, assigned to (-)-salzol, and the structure of the chalcone were determined on the basis of chemical and spectral data
