  Phytochemical and bioactivity studies of Teucrium persicum Boiss. have been investigated on the aerial parts of the plant. About 2 flavonoids, 5-hydroxy 3, 7, 4-trimethoxyflavone and 5-hydroxy 7, 3′, 4′-trimethoxyflavone were purified and identified from chloroform partition by spectroscopy methods. The crude extracts and isolated compounds were screened for their antioxidant activities using DPPH radical-scavenging, FRAP and Reducing power methods. Methanol extract and isolated flavonoids were found to be the most antioxidant active portions.

  No phytochemical investigation regarding Scrophularia striata Boiss. (Scrophulariaceae) has been performed, although several reports about other Scrophularia species have been published. The inhibitory effects of aerial parts of S. striata on matrix metalloproteinase expression elaborate a new approach to treat variety of malignant and inflammatory disorders. Five known compounds, including cinnamic acid, three flavonoids (quercetine, isorhamnetin-3-O-rutinoside and nepitrin) and one phenyl propanoid glycoside (acteoside 1) were isolated from S. striata Boiss. by chromatographic techniques and the structures of compounds were characterized by spectroscopic methods. This is the first report regarding the isolation of these compounds from S. striata.

  Essential oils from the aerial parts of Teucrium persicum Boiss. (Labiatae), collected in 3 stages (pre-flowering, flowering and post-flowering) from plants grown in the Fars province of Iran were obtained by steam distillation. The chemical composition of the oils were analyzed by GC-MS. Analysis of the chemical profile of the isolated oils revealed the presence of >80 compounds, mainly sesquiterpene hydrocarbons, oxygenated monoterpenes and sesquiterpenes. They contained α-terpinyl acetate, α-cadinene, 1,4-cadinadiene, linalool and cadinol. Average yield was 1%. The studied essential oils showed good antioxidant activities as calculated by 3 in vitro assays: DPPH radical scavenging, Ferric Reducing Power Assay (FRAP) and Reducing Power (RP).
