| Abstract:
Salvia officinalis L., S. sclarea L., S. pratensis L. and S. nemorosa L. originated from Hungary and Transylvania were investigated. Tannin and flavonoid content of the S. species were determined and evaluated. Significant differences (p< 0.05) were found for tannin content between Hungarian and Transylvanian S. officinalis and for flavonoid content between Hungarian and Transylvanian S. sclarea. A qualitative comparative study was performed for terpenes from volatile oils by GC and GC-MS technique. The chromatogram of different S. species significantly differed from each other. The spectra of the same sage species originated from different places (e.g. S. officinalis from Hungary and Transylvania) were not qualitative different. Borneol and  -thujone were detected in each sage species whereas linalyl acetate, -pinene and  -pinene were found to be present in three sage species.
Element concentration of samples was determined by ICP-AES for Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, P, Pb, S, Ti and Zn.
The element contrentrations differ significantly between the species and within one species, greatly depend on the place of collection.
The common feature of the species examined seems to be the relatively high chromium content.
The element content of aqueous extract and the dissolution rate were also determined.
