Supercritical fluid extraction of the volatile oil of the aerial part of the winter savory was carried out in different conditions of pressure, temperature, mean particle size and CO2 flow rate and the results were compared with those obtaining by hydrodistillation with a Clevenger-type apparatus. The non-volatile components were extracted by SFE at higher pressures and by soxhlet extraction wi...

A simutaneous distillation extraction (SDE) combined GC method was constructed for determination of volatile flavor components in Pu-erh tea samples. Dichloromethane and ethyl decylate was employed as organic phase in SDE and internal standard in determination, respectively. Weakly polar DB-5 column was used to separate the volatile flavor components in GC, 10 of the components were quantitativ...

A steam distilled volatile oil obtained from the leaves of Chrysanthemum indicum Linn. (FamilyCompositae) was analyzed by capillary GC and GC-MS. The volatile oil mainly comprises of thirty nine (39) components out of which thirty one (31) constituents comprising 82.6% of the oil were identified. The volatile oil mainly contains monoterpenes (48.1%). Isoborneol, a monoterpene, was the predomina...

Gas chromatography-mass spectrometry and multivariate curve resolution were applied to the differential analysis of the volatile components in Agrimonia eupatoria specimens from different plant parts. After extracted with water distillation method, the volatile components in Agrimonia eupatoria from leaves and roots were detected by GC-MS. Then the qualitative and quantitative analysis of the v...

The antioxidant, antifungal and antibacterial potentials of volatile oils and oleoresin of Cinnamomum zeylanicum Blume (leaf and bark) were investigated in the present study. The oleoresins have shown excellent activity for the inhibition of primary and secondary oxidation products in mustard oil added at the concentration of 0.02% which were evaluated using peroxide, thiobarbituric acid, p-ani...
