Nepeta is one of the biggest geniuses of Lamiaceae family which N. pungens, N. binaludensis, N. isphanica, N. pogonosperma and N. bracteata has been used traditionally in Iran. Nepeta pogonesperma is one of the endemic Nepeta species in Alamut region (Qazvin Province ). So in this research the aerial parts of Nepeta pogonesperma in full flowering stage were collected from Kheshchal altitudes of...

Nineteen host plant volatiles (HPVs) were screened for attractivity to adult codling moth Cydia pomonella (L.) as a fourth component of core blends (3K) including (E,Z)-2,4-ethyl decadienoate, (E)-4,8-dimethyl-1,3,7-nonatriene and acetic acid. Each new quaternary combination was compared with previously reported attractive bisexual lure (4K), consisting the 3K blend plus 6-ethenyl-2,2,6-trimeth...

The identification of four further major constituents of the pedal gland exudate of the bontebok, Damaliscus dorcas dorcas, viz. alpha-terpineol, 2-n-heptylpyridine, m-cresol and (A)-6-dodecen-4-olide and the investigation of the stereochemistry of the double bond in (Z)-6-dodecen-4-olide by means of iterative computer analysis are described. An improved synthesis of this compound is outlined.

Abstract The accumulation of soil-borne pathogens is the main driving factor negative plant-soil feedbacks (NPSFs), which seriously restricts sustainable development agriculture. Using natural volatile organic compounds (VOCs) from plants or microorganisms as biofumigants an emerging strategy to alleviate NPSFs in environmentally-friendly way. Here, we identified ?-terpineol VOCs pine needles, ...

BACKGROUND Plant-based traditional system of medicine continues to play an important role in healthcare. In order to find new potent source of bioactive molecules, we studied the cytotoxic activity of the essential oils from the flowers and leaves of Callistemon citrinus. This is the first report on anticancer potential of essential oils of C. citrinus. METHODS Cytotoxicity of essential oil w...

INTRODUCTION A myriad of volatile organic compounds (VOCs) released by terrestrial vegetation plays an important role in environmental sciences. A thorough chemical identification of these species at the molecular level is essential in various fields, ranging from atmospheric chemistry to ecology of forest ecosystems. In particular, the recognition of VOCs profiles in a context of plant-insect ...

During wine aging, tobacco and balsamic aroma notes appear. In this paper, volatile compounds directly or potentially related to those aromas have been investigated in Corvina and Corvinone wines during aging. Corvina and Corvinone are two northern-Italy autochthonous red grape varieties, used to produce Valpolicella Classico and Amarone wines, both characterized by tobacco and balsamic aroma n...

BACKGROUND In the altiplano of Northern Chile the plant Senecio nutans is habitually used as an infusion to relieve the effects of altitude sickness (locally known as "puna"). It is also used to alleviate the bronchitis, whooping cough, asthma, stomachache, tiredness and fever. The extreme conditions under which these plant grow and scientific data that shows the inhibiting potential of the ess...
