Scorzonera latifolia köklerinden izole edilen dihidroizokumarin türevi bileşikler

Özet

Scorzonera latifolia (Fisch. & Mey.) DC. orta ve doğu Anadolu ’da yetişen gok yilhk bir bitkidir.Bu bitkinin köklerinden Türk halk tıbbında analjezik olarak kullamlan, yah sakızi olarak isimlendirilen geleneksel bir sahz elde edilmektedir. Bu gahsmada, S latifolia köklerinden elde edilen metanollü ekstre kimyasal bileşimi agisından araştinlmistır.

Abstract

Scorzonera latifolia (Fisch. & Mey.) DC. is a perennial herb that grows in central and eastern region of Anatolia, Turkey. A traditional mastic named yah sakızı has been prepared from the roots of this plant and used as an analgesic in Turkish folk medicine. In this study, the methanolic extract obtained from the roots of S. latifolia were investigated for the chemical composition. Two dihydroisocoumarin derivatives were isolated from the roots. The compounds were identified as (±) hydrangenol and (-)-scorzotomentosin 4'-0-P-glucopyranoside. The structures were determined using spectroscopic methods ('H-NMR, 13C-NMR, HMBC, HSQQ COSY, TOCSY, NOESY, DEPT) and chemical correlations with known compounds that have been described in the literature.
