In this investigation plant oil and powder of E. aromatica were evaluated under laboratory conditions to determine their toxicity, fumigant effect and impact on F1 progeny of S. oryzae and T. castaneum adults. Essential oil and powder of flower buds obtained from Eugenia aromatica were purified and analyzed by Gas-Chromatography–Mass Spectrometer (GC-MC). The results obtained showed that the two products of E. aromatica had good disorders on the all tested parameters. For toxicity and fumigant effect the oil was the premier compared to powder. In addition, that the two products completely prevented the F1 emergence of the two insects. In respect of the toxicity and fumigation the T. castaneum was more tolerant than S. oryzae adults. Phytochemical analysis showed that euegnol (89.62%) was the premier component of essential oil, while euegnol (78.66%), caryophyllene (6.30%), -a-Terpinyl acetate (1.35%) were the major components for its powder. These findings suggest application of E. aromatica products as suitable tools as a potential source of insecticides, alternative to synthetic insecticides or using these products in integrated pest management program against stored product insects, especially S. oryzae or T. castaneum adults.

Hyssopus Officinalis

Hyssop essential oil is a rich source of biologically active compounds. This study aimed to characterize the chemical composition of essential oil from the hyssop herb and its phytotoxicity against germination and initial growth of wheat and mustard. The main compounds of the oil were identified as isopinocamphone and pinocamphone. In a Petri dish experiment, the oil mainly inhibited the germination and initial growth of wheat, whereas mustard was less affected. In conclusion, hyssop oil displays phytotoxic potential against the studied species and should be tested further.

In Vitro Antioxidant Activity

The essential oil from aerial parts (stems and leaves) of Atriplex undulata (Moq) D. Dietr. (Chenopodiaceae) has been studied for its in vitro antioxidant activity. The chemical composition of the oil obtained by hydrodistillation was determined by GC and GC-MS. The major constituents were p-acetanisole (28.1%), β-damascenone (9.3%), β-ionone (5.1%), viridiflorene (4.7%) and 3-oxo-α-ionol (2.2%). The antioxidant activity of the oil was determined by two methods: Crocin bleaching inhibition (Krel= 0.72 ± 0.15) and scavenging of the DPPH radical (IC50 = 36.2 ± 1.6 μg/mL). The presence of active compounds like p-acetanisole, carvone, vanillin, 4-vinylguaiacol, guaiacol, terpinen-4-ol and α- terpineol could explain the antioxidant activity observed for this oil.

Main Components

The essential oils of four Teucrium species were studied and 131 components, in all, were identified. All oils were rich in sesquiterpenes (50.0-61.9%). Caryophyllene and caryophyllene oxide were the main components of Teucrium arduini; germacrene D, δ-cadinene and γ-cadinene predominated in Teucrium maghrebinum. Carvacrol and caryophyllene predominated in Teucrium polium ssp. capitatum, while carvacrol, caryophyllene oxide and caryophyllene were the most abundant components in Teucrium montbretii ssp. heliotropiifolium. The germination of radish and garden cress was less sensitive to the four essential oils. The radicle elongation, above all, of radish was significantly inhibited by all oils, in particular by the essential oil of T. arduini, at the highest doses tested. Among the main components of the oils, monoterpenes resulted the more active compounds.
