Houseleek leaves (Sempervivum tectorum L.) has a wide application in folk medicine for treating skin changes. Twenty different extracts of houseleek leaves were characterized by spectrophotometry and high-performance thin-layer chromatography (HPTLC). The antioxidant capacity of the extracts was determined using four spectrophotometric assays, while the content of total phenols was determined by the Folin-Ciocalteu's method. The principal component analysis (PCA) was applied to the results obtained by spectrophotometric assays in order to group the samples according to the intensity of antioxidant activity. The samples were divided into two clusters, except for three separated samples. A similar phenolic profile of S. tectorum leaves extracts obtained by HPTLC was observed. Kaempferol and kaempferol 3-O-glucoside, gallic and caffeic acids as well as the quercetin 3-O-glucoside have been identified in houseleek leaves extracts.
