Abstract

In this study, n-hexane, CHCl3 ve MeOH extracts were prepared from dried and powdered aerial parts of C. depressa Bieb. collected from Denizli, Honaz Mountain, (1032 m). Fractionation and isolation procedures were performed on MeOH extract of the plant by using several chromatographical methods (OCC, TLC). As a result, 2 flavone compounds (apigenin and luteolin) and two flavone glcuronopyranoside (skutellarin and 6-hydroxykaempferol-7-O-β-D-glucuronopyranoside) were isolated. Structure elucidation of the pure compounds were carried out by using spectroscopic methods (1H and 13C NMR). Furthermore a phytosterol (β-sitosterol-3-O-β-D-glucopyranoside), a phenylpropanoid glycoside (syringin) and a phenolic acid (chlorogenic acid) were identified by using several TLC techniques and standart compounds. All compounds are reported for the first time on C. depressa in this work

Özet

Bu çalışmada, Denizli Honaz Dağı, 1032 m’den toplanan C. depressa Bieb.’in kurutulmuş ve öğütülmüş toprak üstü kısımlarından, n-hekzan, CHCl3 ve MeOH ekstreleri hazırlanmıştır. MeOH ekstresi üzerinde çeşitli kromatografik yöntemler (AKK, İTK) kullanılarak fraksiyonlama ve izolasyon işlemleri gerçekleştirilmiştir. Sonuç olarak, ülkemiz tıbbi bitkilerinden olan C. depressa’dan iki flavon bileşiği (apigenin ve luteolin) ve iki flavon glukuronopiranozidi (skutellarin ve 6-hidroksikemferol-7-O-β-D-glukuropiranozit) izole edilmiştir. Saf maddelerin yapıları spektroskopik yöntemler (1H ve 13C NMR) kullanılarak aydınlatılmıştır. Ayrıca bitkide bir fitosterol (β-sitosterol-3-O-β-D-glukopiranozit), bir fenilpropanoit glikoziti (siringin) ile bir fenolik asit (klorojenik asit) bulunduğu çeşitli İTK yöntemleri ve standart bileşikler kullanılarak saptanmıştır. Tüm bileşikler, C. depressa’da tarafımızdan ilk kez rapor edilmektedir
