Metodami chromatograficznymi, w liściach i organach podziemnych S. carniolica Jacq., S. lurida Dun. i S. sinensis Hemsl. stwierdzono obecność następujących kwasów: protokatechowego, p-kumarowego, kawowego, ferulowego, synapinowego i chlorogenowego. W liściach i organach podziemnych S. lurida dodatkowo zidentyfikowano kwas p-hydroksybenzoesowy i wanilinowy. Badania wskazują, że kwas chlorogenowy i kawowy są dominującymi składnikami analizowanych surowców.

The toxicity and biological activity of aqueous extracts of herbal medicine Naran N were investigated using human skin fibroblast cells culture (HSF) of 2 x 104 and 1 x 10s cells/ml densities. The herbal drag Naran N is composed of four herbs: Flos Calendulae, Folium Plantaginis lanceolatae, Anthodium Chamomillae, Herba Euphrasiae; it was elaborated in the Department of Chemistry, Pharmaceutical Falcuty of Medical University of Lublin (Poland) and distributed on permission ofthe Polish Department of Hygiene (PZH) in 2001. Naran N is produced by Dyspak (Dys near Lublin, Poland) on licence of the Medical University of Lublin (PL-409218-B,). The investigations in the Institute of Microbiology and Biotechnology of UMCS of Lublin have shown that the aqueous extract of Naran N stimulates the proliferation of HSF cells of 1 x TO5 cells/ml density, the viability of cells remained on the control level. Similar viability was observed also for HSF culture of 2 x 10" cells/ml density. The results explain the healing activity of Naran N for chronic vascular diseases.

The content of phenolic acids was determined by high performance thin-layer chromatography and densitometry and by HPLC in herbal preparation Naran N elaborated in the Department of Chemistry of the Medical University in Lublin, Poland. Methanolic extracts from plant components of Naran N: Anthodium Chamomillae, Herba Euphrasiae, Folium Plantaginis lanceolatae, Flos Calendulae were analysed. In the extract from Anthodium Chamomillae protocatechuic, vanillic, ferulic, caffeic, chlorogenic and p-coumaric acids were identified; in the extract from Herba Euphrasiae p-coumaric, ferulic, caffeic, protocatechuic, vanillic, chlorogenic and 3-hydroxybenzoic acids, in the methanolic extract from Folium Plantaginis lanceolatae vanillic, p-coumaric, caffeic, ferulic, chlorogenic and protocatechuic acids were found; the same number of phenolic acids were detected in the methanolic extract of Flos Calendulae, these were p-coumaric, caffeic, syringic, chlorogenic, vanillic, protocatechuic and ferulic acids.
