objectives: evaluation of therapeutic effects of carum copticum (c. copticum) has been the subject of several studies in recent years. thymol the major component of c. copticum is a widely known anti-microbial agent. in this study, the antibacterial and anti viral activities of essential oil of c. copticum fruit were determined. materials and methods: essential oil of c. copticum was analyzed b...

background and objectives: essential oils may improve the utilization of nutrients by ruminal microorganisms. the aim of this study was to assess the effect of different doses of ajowan essential oils (aeo) on growth and fibrolytic activity of anaerobic fungi, and generic distribution of ciliated protozoa ( in vitro ). material and methods: different doses of aeo (0, 150, 300, 450 and 600 ppm) ...

The chemical composition of the essential oils of the wild growing plants of Greek S. spinosa L., S. parnassica subsp. parnassica Heldr.& Sart ex Boiss., S. thymbra and S. montana were determined by GC and GC/MS analysis. The larvicidal activities of the essential oils were assayed against Culex pipiens biotype molestus. The analytical data indicated that various monoterpene hydrocarbons and ph...

This paper shows the changes of the volatile compounds from four Astragalus species at three phenological stages: leaf development, flowering and fructification, which might be connected with the plant defense. After GC/MS analyses of Astragalus glycyphyllos L., A. hamosus L., A. cicer L. and A. spruneri Boiss., different groups of volatile compounds were found: hydrocarbons, alcohols, aldehyde...

Two new lignans (R,Z)-3-(3,4-dimethoxybenzyl)-2-(3, 4-dimethoxybenzylidene)-gamma-butyrolactone (1) and (2R, 3S)-2-acetoxy-2,3-bis(3,4-dimethoxybenzyl)-gamma-butyrolactone (2), and four new polyacetylenes, (2Z,8E,10E)-heptadeca-2,8,10-triene-4, 6-diyn-1-ol (3), (2E,9Z)-octadeca-2,9-diene-4,6-diyne-1,18-diol (4), (2E,9Z)-18-hydroxy-octadeca-2,9-diene-4,6-diyn-1-yl acetate (5), and (2E,9Z)-1-hydr...

From the whole plant of Dracocephalum kotschyi BOISS., two new monoterpene glycosides (9, 10), together with seven known terpenoids and a phytosterol (1-8), were isolated. Their structures were determined to be limonen-10-al (1), geranial (2), neral (3), beta-sitosterol (4), oleanolic acid (5), ursolic acid (6), p-mentha-8-en-1,2-diol (7), colosolic acid (8), limonen-10-ol 10-O-beta-D-glucopyra...
