title: Sesterterpenoids and other constituents of Salvia sahendica.
abstract: A new sesterterpene (1), a new norsesterterpene (3), and two new norditerpenes (4, 5) were isolated from the aerial parts of Salvia sahendica, together with 12 known compounds, comprising a sesterterpene, a sesquiterpene, a diterpene, two triterpenes, two steroidal compounds, and five flavonoids. The structures of the new compounds were established by spectroscopic data interpretation, and in the case of 4, its structure was confirmed by single-crystal X-ray analysis.
