Twenty naturally occurring monoterpenoids were evaluated in a preliminary fumigation screening test on some important stored-product pest insects, including the rice weevil, Sitoplzilus oryzae, the red flour beetle, Tribolium castaneum, the sawtoothed grain beetle, 0rj)zaephilus surinamensis, the house fly, Musca dornestica, and the German cockroach, Blattella germanica. Cineole, 1-fenchone, an...

Cultivation of mint timija (Mentha suaveolens subsp. timija (Briq.) Harley) constitutes a promising solution to the conservation and sustainable utilization of this Moroccan endemic and threatened species. Optimized agronomic practices require mineral and/or biological fertilizer applications. The aim of this study was to determine the effects of application of a complete (N, P, and K) mineral ...

BACKGROUND Bird damage to seeds and seedlings of maize (Zea mays) and other crops is widespread, especially in organic farming, because no adequate seed protection is available. In this study, the effect of seed treatments with three substances likely to affect bird feeding behaviour (anthraquinone, pulegone and methyl anthranilate) was tested. Their repellent effect was tested in food and seed...

A GC-MS-Selected Ion Monitoring (SIM) detection method was developed for simultaneous determination of four monoterpenes: (-)-menthone, (+)-pulegone, (-)-limonene and (+)-menthofuran as the main bio-active and toxic constituents, and four other main compounds in the volatile oils of Schizonepeta tenuifolia (ST) leaves and spikes at different harvesting times. The results showed that the method ...

Background: The widespread use of specialized food products, including plant-based dietary supplements, is determined by a rich variety biologically active constituents. However, some plants containing such bioactive compounds as pulegone, menthofuran, estragole, methyleugenol, safrole, and thujone may cause adverse health effects. Objective: To review recent domestic international scientific p...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

background recurrent pregnancy loss (rpl) is a serious problem for pregnancy. there is evidence that vascular complications play a principal role in rpl. methylenetetrahydrofolate reductase (mthfr) is a key enzyme in folate metabolism. polymorphisms (c677t, a1298c) of mthfr gene are associated with decreased mthfr activity. objectives the aim of this study was to determine the association betwe...

Background & Aim: Essential oil of pennyroyal (Mentha pulegium L.) has many applications in food, perfume and pharmaceutical industries. The aim of this study was to determine the content and chemical constituents of pennyroyal essential oil growing wild in Southern Iran. Experimental: The aerial parts of the plant were collected around Hajiabad, Hormozgan province in 2013. The essent...
