The contents of total phenolic compounds and flavonoids were determined in acetone extracts from different plant parts of Teucrium montanum (mountain germander) using spectrophotometric metods. Teucrium montanum L. (Lamiaceae) is a perennial, shrub-like plant with half-ligneous branches, up to 25cm high and inhabits thermophilic rocks, dry mountain meadows and edges of forests in Europe and Anatoly [1]. It is used as a diuretic and in the treatment of digestive and respiratory diseases and possesses antiinflammatory [2], antioxidative [3] and antimicrobial effect [4]. The phenolic content of the extracts from plant part ranged from 50.36mg/g to 114.84mg/g dry weight of extract, expressed as gallic acid equivalents. The total flavonoid content varied from 37.32mg/g to 88.31mg/g expressed as rutin equivalents. The amount of phenolic compounds and flavonoids is very uneven in different parts of the plant. The highest content of phenolic compounds (114.84mg/g) was recorded in acetone extract of flowers and the highest content of flavonoids (88.31mg/g) was measured in acetone extract of leaves. Herbal extract from stem contains very low concentrations of phenolic compounds and flavonoids. Obtained values indicate that the flowers and leaves of Teucrium montanum species are very rich sources of phenolic compounds.
