PRELIMINARY CHROMATOGRAPHICRESEARCH ON SOME SALVIA SPP. (LAMIACEAE)

Abstract

Salvia genus, representative for the Lamiaceae family as it comprises approximately one thousand different species, is considered for a wide plethora of therapeutic actions, such as antioxidant, anti-inflammatory, hepatoprotective, antitumoral and antidiabetic activity. The paper presents the preliminary chromatographic investigations of the polyphenols in the aerial parts of some Salvia spp. Using high-performance thin-layer chromatography (HPTLC) coupled with photodensitometry, caffeic acid was identified and quantified in the 20% methanolic extracts of Salviaeherba, in descending order, as follows: S. nemorosa (3.096%) > S. verticillata (3.041%) > S. sclarea (2.663%) > S. glutinosa (1.962%) > S. aethiopis (0.926%).
