Abstract
Centaurea ptosimopappoides was previously investigated by our group
and the presence of two new triterpenes were reported. The rare occurrence of
this type compounds in the plants prompted us to further investigation of Centaurea ptosimopappoides. In this work we report the isolation and structure determination of an aromatic glycoside which was found in the genus Centaurea
for the first time. The structure of the compound was determined by spectral
methods.The genus Centaul-ea contains various types of compounds, therefore its has been the subject of many chemical investigations. Sesquiterpene lactones, acetylenes, flavonoids and coumarins are the main secondary metabolites of this genus. In a part of our continuing research on the chemistry of Centaurea species, we have studied Centaurea ptosimopappoides Wagenitz, a plant endemic to Turkey, which is widely distributed in the southern part of Anatolia. Previous investigation with the roots of this species, we reported the presence of two new triterpenoids of which one was a baccharane type triterpene, occurs rare in nature

Abstract
Centaurea ptosimopappoides bitkisi daha once grubumuz tarafmdan q&- 91hg ve iki yeni triterpen bilegiginin molekiiler yapllan agdclanrmgtlr. Bu tip bilegiklerin bitkilerde ender bulunmas~ nedeniyle Centaurea ptosimopappoides t6riini.i kirnyasal balumdan tekrar inceledik. Bu gahgmarmzda aromatik glikozit yapls~ndaki bir bilegik elde ettik. Bu bilegik bir Centaurea tiiriinden ilk kez elde edilrnektedir. Bilegib yap1 tayininde spektroskopik yonternlerden yararlmlmgtlr.
