Evaluation of phytochemical content, antioxidant, antimicrobial activity and DNA cleavage effect of endemic Linaria corifolia Desf. (Plantaginaceae)

Abstract The aim of this study is to isolate Linaria corifolia Desf. (Plantaginaceae) and identify new apigenine derivatives 6,3′-dimethoxyapigenin-7-O-[(rhamnosyl)-(1–2)-6″-acetyl glucoside]. Moreover, we analyzed biological activity and flavonoids by using HPLC methods from extracts. The L. corifolia Desf. samples were collected in Black Sea Region of Turkey. Ethanol (EtOH), ethyl acetate (EtOAc) and dichloromethane (DCM) extracts in aerial and under solid parts of plant were evaluated for antioxidant, antimicrobial activity and effect of DNA cleavage. Quercetin, gallic acid and catechin as flavonoids were identified in EtOH, EtOAc, DCM extracts.

Mountainous Vegetation of Central Black Sea Region

Central Black Sea Region includes many different vegetation types. At high elevations, forest vegetation is dominant. Some forest types have closed canopies, while some of them can be disturbed mainly due to anthropogenic factors (grazing, clear-cutting, etc.). Oceanic climate is seen in northern slopes, while continental climate is also seen especially in inner parts of the region. Continental climate is also seen in inner parts of stream valley (e.g., Kizilirmak valley). Mediterranean climate is also penetrated in inner parts of the region. As a result of this, it is impossible to draw a demarcation line among different vegetation types. For example, some forest communities include Euxine, steppe, and Mediterranean-type communities and phytosociological classification is too difficult.
