Article: Phytochemical composition and in vitro pharmacological activity of two rose hip (Rosa canina L.) preparations.(Report)

Abstract

The aim of the present study was to compare powdered rose hip with and without fruits (Rosa pseudofructus cum/sine fructibus, Rosa canina L., Rosaceae) with regard to their phytochemical profile and their in vitro antiinflammatory and radical-scavenging properties. The two powders were subsequently extracted with solvents of increasing polarity and tested for inhibition of cyclooxygenase (COX-1, COX-2) and of 5-LOX-mediated leukotriene [B.sub.4] (LT[B.sub.4]) formation as well as for DPPH-radical-scavenging capacity. While the water and methanol extracts were inactive in the COX-1, COX-2 and LT[B.sub.4] inhibition assays, the n-hexane and the ...
