two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of salvia sharifii. the compounds were purified using several chromatographicmethods. structural elucidation of the compounds was performed using their 1h and 13c-nmrdata, ei mass and uv spectral data. the co...

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...

The biological activity and composition of the essential oil of Sclerorhachis leptoclada Rech. an endemic species from northeast of Iran was studied. The essential oil was isolated from the aerial flowering parts of the plant and analyzed by GC and GC-MS. Fifty-four compounds accounting for 95.9% of the total oil were characterized. The main constituents were (E)-nerolidol (14.5%), terpinen-4-o...

Satureja genus presents 12 aromatic species in Iran, eight of which are endemic. Because of the several usages of Satureja species or their oils in different industries, we were interested to study the oil content and composition of Iranian Satureja species. In this research, the essential oil content and composition of two endemic species (S. edmondi and S. isophylla) were investigated. Essent...

In order to optimize callus induction in Pistacia atlantica Desf. subsp. kurdica Rech. f., the effect of different plant growth regulator (PGR) combinations were studied. Inflorescence axis explants were cultured on WPM medium supplemented with 1, 2 and 3 mg/L of TDZ or 1, 2 and 3 mg/L of BA, in combination with 1mg/l different auxins: 2, 4-D,  NAA  and IBA . Callus initiation was observed in a...
