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...

This study was designed to examine the chemical composition and in-vitro antioxidant activity of the essential oil and methanolic extract of Teucrium orientale subsp. taylori. The GC and GC–MS analysis of the essential oil resulted in determination of 40 components representing 96.4% of the oil. The major constituents of the oil were linalool (28.6%), caryophyllene oxide (15.6%), 1,8-cineol (4....

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 software engineering crisis was diagnosed about a half a century ago. Since then a plethora of methods, methodologies, notations, programming languages and environments have been developed and significant progress has been made. However, the nature and complexity of the software being developed has also changed and this has nearly annulled this progress. High rates of software failure conti...

: in this study, the essential oil obtained by hydrodistillation of the aerial parts of sclerorhachis platyrachis (boiss.) podlech ex rech. f. (compositae), growing wild in sabzevar, khorasan razavi province (iran), was analyzed by gc and gc/ms. the total yield of volatiles was 0.38% (w/w). sixty- three compounds representing 89.2% of the aerial parts oil were identified.  the main components o...
