Subject:
Senecio vernalis; aerial parts; alpha-phellandrene; cineole; essential oils; flowering; gas chromatography-mass spectrometry; oils; spathulenol; Iran
Abstract:
... The volatile constituents of the aerial parts of Senecio vernalis growing wild in Iran have been characterized by GC-FID and GC-MS. The oil was found to contain 13 components. Altogether, 10 compounds were identified from the aerial parts of this plant, collected during its flowering stage. The oil was rich in spathulenol (37.1%), 1,8-cineol (19.0%), m-cymene (16.6%). The other major constituents ...

Abstract:
... In this study the antimicrobial activities of five volatiles, which represent main compounds of several essential oils, were tested. Terpineol, (R)-(-)-linalool, carvacrol, (S)-(-)-perillaldehyde and 1,8-cineole were evaluated for their influence on airborne microbes when vaporized with a room diffuser. In the present investigation terpineol and (S)-(-)-perillaldehyde showed the highest antimicrob ...

Abstract:
... The objective of this study was to compare the effectiveness of various antioxidants in slowing sulphur flavour compound oxidation in oil matrix. A model aroma compound mixture was prepared in sunflower oil and stored for 8 weeks. Six systems were studied, in which samples contained: 0.01% δ-tocopherol; 0.05% rosemary extract or a mixture of 0.02% (ratio 1:1) δ-tocopherol and ascorbyl palmitate; o ...

Subject:
equations; flavor; gas chromatography; odors
Abstract:
... The main purpose of any chromatographic analysis is to resolve mixtures of compounds into less complex mixtures or ultimately into pure components. In addition to this function, the chromatographic system can provide retention data which serve as complementary information for the positive identification of resolved components. The need to express gas chromatographic retention data in a standardize ...

Abstract:
... Mentha cervina L. is an aromatic plant that is traditionally used in the Alentejo region of Portugal to flavour food dishes and for the medicinal properties of the essential oil produced in its glandular trichomes. The morphology and distribution of the secretory structures of 20 populations was studied by light and scanning electron microscopy and revealed a great similarity in the type and distr ...

Abstract:
... Cerebral malaria is a major health problem in the developing world. Widespread resistance to existing drugs by the parasite Plasmodium falciparum has coincided with an increase in mortality, particularly in children. One potential source of new drugs comes from plant natural products. We found that commercially available, pharmaceutical grade eucalyptus oil and its principal component 1,8-cineole ...

Abstract:
... The enzymatic synthesis of flavour esters by trans-esterification from vinyl esters and alcohols catalysed by free Candida antarctica lipase B (CaLB) in ionic liquids has been studied. The influence of different parameters, such us pH, temperature and ionic liquid nature, on activity and selectivity has been carefully analysed, using as reaction model the synthesis of butyl butanoate. Finally, a b ...
