AbstractEssential oil (EO) was extracted from Callistemon citrinus leaves by hydro-distillation. The extracted oil was analysed by GC and Mass Spectroscopy. Analysis report showed that the major constituent of the essential oil was eucalyptol (40.44%). The EO of C. citrinus exhibited 100% fumigation toxicity (adult mortality) against adult and 95.8% larvicidal activity against Tribolium castaneum at 160 μL/L (12 hrs) and 320 μL/L (48 hrs), respectively. The effective concentration of 37.05 μL/L (adult) and 144.31 μL/L (larva) at 24 and 48 hrs respectively. A 100% repellent activity was observed at 20 μl for adult beetles and 93.3% for larvae of T. castaneum at 20 μl after 24 h. Exposure to C. citrinus EO significantly reduced beetle fecundity, ovicidal activity, egg hatching, larvae survival, and emergence of adult. The effect of EO on detoxification enzymes of T. castaneum adults was examined. Results indicated that the activity of detoxification enzymes drastically varied when compared with control. This EO had toxicant effects on all stages of the life of T. castaneum. Hence it may be used as fumigant instead of the use of using synthetic chemical fumigants.

The essential oil composition of the leaves, stem, flowers and roots of Ligusticopsis wallichiana (DC.) Pimenov & Kljuykov were analyzed by GC-FID and GC-MS methods. Forty-five constituents, forming 93.2%–97.8% of the oil compositions, were dominated by acetylenic (31.5%–92.8%) compounds and sesquiterpenoids (0.3%–44.4%). The leaf essential oil was mainly composed 3,5-nonadiyne (35.8%), β-selinene (20.9%), α-funebrene (10.1%) and ( Z)-falcarinol (6.1%). The stem oil was dominated by acetylenic compounds (73.8%) represented by 3,5-nonadiyne (67.8%) and ( Z)-falcarinol (5.7%). On the contrary, the major components of the flower essential oil were sesquiterpenoids (37.5%), such as germacrene D (16.6%), α-funebrene (7.4%), and acetylenic compounds (31.5%), such as ( Z)-falcarinol (21.0%) and 3,5-nonadiyne (10.0%). Monoterpenoids constituted 23.9% of the flower oil with limonene (19.9%) as the single major constituent. The essential oil of the roots was dominated by 3,5-nonadiyne (90.5%). The results showed considerable qualitative and quantitative variations in the essential oil compositions of the different plant parts of L. wallichiana. ( Z)-Falcarinol (1.9%–21.0%) and α-funebrene (0.1%–10.1%) were reported for the first time from the essential oils of L. wallichiana.

The essential oil from the aerial parts of Blumea perrottetiana was obtained by hydrodistillation and analyzed by GC-MS. The volatile oil is dominated by 2,5-dimethoxy- p-cymene (30.0%) and 1,8-cineole (11.0%) with lesser amounts of sabinene (8.1%), δ-cadinene (5.3%) and ( E)-caryophyllene (3.9%). The essential oil demonstrated notable insecticidal activity against the red flour beetle, Tribolium castaneum, consistent with traditional uses of the plant as an insecticide and anthelmintic.

Pulicaria incisa (Lam) is a wild-growing plant in Morocco and has been traditionally used by farmers to control pests of stored grains. The present study was conducted to investigate the chemical composition and insecticidal effect of the essential oil of P. incisa against Sitophilus oryzae (L.) and Tribolium castaneum (Herbst.) by different methods (contact, fumigation and ingestion). The aerial parts of the plant were subjected to hydrodistillation using a Clevenger-type apparatus. The essential oil composition was analyzed by gas chromatography (GC) and mass spectrophotometry (MS). Sixty-six compounds representing 89.4% of total oil were identified. The main components were α-Ocimene (15.17%), τ-Cadinol (6.79%), α-Cadinol (4.51%), Alloaromadendrene (4.45%) δ-Cadinene, (+) - (4.13%). The repellant toxicity test results revealed a higher repellency effect in S. oryzae than T. castaneum. Lethal concentration (LC50), varied between 15.49 - 1.73 μL/cm2 and 20.89 - 2.29 μL/cm2 respectively. In the fumigation test, adults of S. oryzae and T. castaneum were sensitive to the essential oil with LC50 values varying between 16.21 - 2.08 and 18.62 - 2.51 μL/L air. In addition, experiments have shown that the ingestion method is the most toxic towards both insects with LC50 values of the order of 12.59 - 1.51 μL/g for S. oryzae and 14.12 - 2.39 μL/g for T. castaneum. While the lethal time (LT50) values decreased with increasing essential oil concentration, and in all cases, the increased susceptibility of both insects was directly associated with oil concentration and exposure time. This study aims to valorize medicinal and aromatic plants of the Moroccan flora in order to find novel bio-insecticidal products. Furthermore, the study reports for the first time the insecticidal activity of P. incisa against adults S. oryzae and T. castaneum.

Essential oil compositions of Nepeta glomerulosa Boiss. subsp. glomerulosa and N. glomerulosa subsp. stapfiana (Bornm. ex Rech. f.) Rech. f., each gathered from two different locations, have been investigated by GC and GC/MS. 1,8-Cineole was the major compound in the oils of both collections of subspecies glomerulosa (27.4%, 30.6%), and was also a major constituent of subspecies stapfiana (14.9%, 17.8%). However, caryophyllene oxide was the predominant compound for both oils of subspecies stapfiana (32.0%, 24.1%). From the chemotaxonomic point of view, the two members of each subspecies comprised a separate group with a considerable distance from the other two, and the morphological differences of these two subspecies were well reflected in their essential oil compositions.

Antimicrobial And Antioxidant Activity

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.
