title: Chemical constituents from the cell cultures of Saussurea involucrata.
abstract: The chemical constituents of the cell cultures of Saussurea involucrata were systematically investigated, thus a new eudesmane-type sesquiterpene together with 14 known compounds was isolated. Among them, syringin is the main compound with an isolated yield of 0.3%. The new compound was characterized as 11 beta H-2 alpha-hydroxy-eudesman-4(15)-en-12,8 beta-olide (1) on the basis of extensive spectroscopic data.
