Essential oils obtained from aerial parts of Artemisia persica and Artemisia turcomanica were analyzed by GC/MS. While 28 components representing 91.01 % of A. persica were identified, the identity of 50 components, constituting 81.93 % of the total oil, was confirmed in A. turcomanica. β-thujone was the main compound (75.23%) in A. persica while the major identified phytochemicals in A. turcom...

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....

mulberry pyralid, glyphodes pyloalis walker is an important pest on mulberry. the essential oil of rosemary rosemarinus officinalis l. (lamiales: lamiaceae) has been investigated on toxicity and physiological characteristics of this moth under controlled conditions. the major compounds of the oil were analyzed as 1, 8 cineol (20.021%), borneol (7.17%), camphor (6.541%), geraniol (6.281%), camph...

the essential oil obtained by hydrodistillation of flowers of calycanthus floridus l. var.oblongifolius (nutt.) d.e. boufford & s.a. spongberg, planted in sabzevar, khorasan province(iran), was analyzed by gc and gc/ms. eighteen compounds representing 90.1% of theflower oil of calycanthus floridus l. var. oblongifolius were identified, among them 1,8-cineol(33.1%), bornyl acetate (14.1%), α-pin...

the two spotted spider mite tetranychus urticae koch is one of the polyphagous pests of crops worldwide. due to undesirable effects of synthetic pesticides such as expression of resistance in mites, this research was conducted to achieve alternative safe compounds to environment. therefore, ovicidal activity of essential oils of eucalyptus salmonophloia f. muell and eucalyptus kingsmillii maide...

Peppermint, (Mentha ×piperita), aromatic perennial herb of the mint family (Lamiaceae). It is a natural hybrid Mentha spicata and aquatica found wild with its parent species in central as well southern Europe. holds various types ingredients including menthol, menthone cineol. Menthol, which extracted from peppermint, play an important role inhibition pathogenesis. Peppermint oil also acts mild...

The present study investigated the chemical composition of the essential oil (EO) from aerial parts (flowering stage) of Achillea wilhelmsii C. Koch by GC-MS. In addition, the antioxidant activity of the EO as well as its antimicrobial activity against methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MRSA) strains was tested. Antioxidant activity was measured by the abil...

This study was carried out to determine the in vitro antimicrobial and antioxidant activities of the essential oil, seed oil, and methanolic extract of seed oil obtained from Laurus nobilis L. (Lauraceae). The methanolic extract of seed oil exhibited more effective antibacterial activity comparing to essential oil and seed oil, GC-MS analyses of the essential oil resulted in the identification ...

The monoterpenoid 1,8-cineole is obtained from the leaves of Eucalyptus globulus and it has important biological activities. It is a cheap natural substrate because it is a by-product of the Eucalyptus cultivation for wood and pulp production. In this study, it was evaluated the potential of three filamentous fungi in the biotransformation of 1,8-cineole. The study was divided in two steps: fir...
