The chemical composition of the essential oils obtained from the aerial parts of Helichrysum cymosum and H. fulgidum, from Tanzania, were analyzed by GC and GC/MS. A total of sixty-five compounds, representing 92.4% and 88.2% of the two oils, respectively, were identified. trans-Caryophyllene, caryophyllene oxide, β-pinene, p-cymene, spathulenol and β- bourbonene were found to be the main components. Furthermore, the oils were tested against six gram (±) bacteria and three pathogenic fungi. It was found that the oil of H. fulgidum exhibited significant antimicrobial activity, while the oil of H. cymosum was not active at all.

The chemical composition of the essential oils of Achillea holosericea, Achillea taygetea, Achillea fraasii was determined by GC/MS analysis. Among the ninety-five assayed constituents, camphor, borneol and 1,8-cineol were found to be the major components. The in-vitro antimicrobial activity of these essential oils was evaluated against six bacteria indicating that the first is totally inactive, while the other two possess moderate to strong activities mainly against the Gram negative strains. The essential oil of A. fraasii was also active against the tested pathogenic fungi

Cymbopogon species from the Poaceae family are widely distributed in the Himalayan region of India and commonly used as flavors, fragrances, cosmetics, and pharmaceuticals. It is known to contain compound citral, which give the lemon scent to many of the plants of the cymbopogon genera. The essential oil of  Cymbopogon flexuosus has high polyphenolic content which is responsible for antioxidant properties.  Beside citral is also used for the synthesis of vitamin B and Ionones. The bioactive potential of Lemongrass and constituent are rapidly increasing which is reflected from growing number of reports being published.  The present study was to know the chemical composition and in vitro antioxidant activity of essential oil of C. flexuosus from Uttarakhand. The essential oils of Cymbopogon collected in the region of Uttarakhand were obtained by hydrodistillation of the leaves and analyzed for chemical composition by GC/MS. The antioxidant activity of essential oils at different concentrations was determined against DPPH radical activity and vitamin C as the standard antioxidant compound.  The IC50    value and percentage of DPPH inhibition were recorded.  Twenty-five compounds were identified in essential oil extracted from leaves representing 93.15% of the oil composition. The yield of essential oil of Cymbopogon was 0.6 + 0.1 %and the major compound in the essential oil was citral (a racemic mixture of two isoforms geranial and nearl) followed by heptenone(1.98%) , linalool(1.65%), geraniol (1.47%), ?-caryophyllene (1.14% ) , limonene (0.92%),  nearl acetate (0.82%), citronellal(0.44 %) and citronellol (0.22%). Radical scavenging capacity (Inhibition, %) of the C. flexuosus essential oil was high (78.19+1.11) at the concentration level of 150 ?g/ml and  IC50 value of the essential oil was 43.67?g/ml.  The data of this study encourages to consider the essential oil of C. flexuosus  as a source of bioactive compounds which may add great industrial value to this crop.

The chemical composition of 10 selected plant essential oils obtained by steam distillation was determined by GC and GC/MS. The antimicrobial activity of the essential oils was screened against 12 important food-related bacterial strains by agar disc-diffusion assay. MIC and MBC were determined for the essential oils that presented the highest activity in the agar disc-diffusion test. The most active essential oils against the tested bacteria were, in descending order, lemongrass (Cymbopogon flexuosus), basil (Ocimum basilicum), oregano (Origanum vulgare), cinnamon leaf (Cinnamomum zeylanicum), and laurel (Laurus nobilis). Except for S. Typhimurium, the tested bateria were inhibited at MIC values lower or equal to 0.62mg mL-1 by lemongrass (Cymbopogon flexuosus) essential oil. Yersinia enterocolitica presented the highest sensitivity to all essential oils tested (CMI≤0.62mg mL-1). There was a significant correlation (P<0.05) between oxygenated monoterpenes levels in the essential oils and MIC and MBC values against Escherichia coli. Results showed that the evaluated essential oils present high potential as natural preservatives.

The chemical composition of volatile fractions from leaves, flowers and peels of Citrus aurantium growing in Tunisia obtained by hydrodistillation were analysed using GC and GC-MS. Furthermore, the isolated essential oils were evaluated for their in vitro antimicrobial activity against eight bacteria, eight phytopathogenic and nine human pathogenic fungi. The essential oils from peels and its main compound limonene have been found to possess strong contact toxicity against four storage-grain insects. The highest mortality rate was observed when the essential oil was applied against Cryptolestes ferrugineus, Liposcelis bostrychophila and Tribolium castaneum.
