title: [Triterpenes and steroidal compounds from cynomorium songaricum].
abstract: From the whole parasitic plant of Cynomorium songaricum Rupr. three ursane type triterpenes, three steroidal compounds, palmitic acid and sucrose were isolated. The triterpenes were identified as acetyl ursolic acid (2), ursolic acid (3) and a new compound, ursa-12-ene-28-oic acid, 3 beta-propanedioic acid monoester (1). The steroidal compounds were identified as beta-sitosterol palmitate (4), beta-sitosterol (5) and beta-sitosterol glucoside (daucosterol, 6).
