“…OCO was previously reported to have different major compounds such as camphor (37,38), 1,8-cineole (39), citral (40), eugenol (41), geraniol (32), and linalool (42). However, in the present study, E-citral (41.01%) and Z-citral (37.04%) were found at the highest level in this EO.…”

“…As a monoterpene compound, Linalool is a major component of essential oils in lots of aromatic species (Elisabetsky et al, 1995), and present in the dried leaves of cinnamomum camphora (Weaver et al, 1991). Due to promising biological activities including cytotoxic (Yang et al, 2014), anti-microbial (Bagamboula et al, 2004), insect-repellant properties (Beier et al, 2014), anti-inflammatory activity (Peana et al, 2002), antihyperglycemic (Weaver et al, 1991;More et al, 2014), antitumorigenic potential (Jana et al, 2014) and sedative effects, linalool as a natural plant-product has been extensively applied in various fields, such as perfumes, cosmetics, flavoring agents and medical science (Re et al, 2000).…”

Linalool has been extensively applied in various fields, such as flavoring agent, perfumes, cosmetics and medical science. However, linalool is unstable, volatile and readily oxidizable. A sensitive substance can be encapsulated in a capsule, so encapsulation technology can solve these problems. In this paper, linalool-loaded nanocapsules (Lin-nanocapsules) were prepared via the ionic gelation method and Lin-nanocapsules were characterized. The results of Fourier transformation infrared spectroscopy (FTIR) showed that linalool was successfully encapsulated in the wall materials. Scanning electron microscopy (SEM) results demonstrated that the shapes of Lin-nanocapsules, with smooth surfaces, were nearly spherical. Lin-nanocapsule average particle size was 352 nm and its polydispersity index (PDI) was proved to be 0.214 by the results of dynamic light scattering (DLC). Thermogravimetric results indicated that linalool loading capacity (LC) was 15.17%, and encapsulation could decrease linalool release and increase linalool retaining time under the high temperature. Oscillatory shear and steady-state shear measurements of Lin-nanocapsule emulsions were systematically investigated. The results of steady-state shear showed that Lin-nanocapsule emulsion, which was Newtonian only for high shear rate, was non-Newtonian. It was proved by oscillatory shear that when oscillation frequency changed from low to high, Lin-nanocapsules emulsion changed from viscous into elastic.Keywords: lin-nanocapsules; flavor; encapsulation; rheology.Practical Application: Lin-nanocapsules were prepared via the ionic gelation method.

“…Plant extracts have shown ovicidal, repellent, antifeedent and toxic effects in insects (Isman et al 1990;Isman 2006;Devi and Devi 2011). Essential oils and their individual constituents have been known to play an important role as protectants of stored grains and proved to possess repellent and insecticidal properties (Weaver et al 1991;Sim et al 2006;Yao et al 2008). The organic extracts from root powder of Decalepis hamiltonii (Wight and Arn) showed potential to be used as grain protectant against grain insect pests .…”

Leaves of Lantana camara Linn. (Verbenaceae) as a potential insecticide for the management of three species of stored grain insect pests

Insects cause extensive damage to stored grains and their value added products. Among the stored grain pests Sitophilus oryzae (L.) Callosobruchus chinensis (Fab.) and Tribolium castaneum (Herbst.) are considered as destructive pests in India. Plants may provide alternatives to currently used insect control agents as they constitute rich source in bioactive molecules. Lantana camara, an erect shrub, which grows widely in the tropics, exhibits insecticidal activity against several insects. The methanol extract from leaves of L. camara has fumigant and contact toxicity against S. oryzae, C. chinesis and T. castaneum. In fumigant assays, The LC 50 for S. oryzae was 128 μl/L 1 , C. chinensis 130.3 μl/L 1 , and T. castaneum 178.7 μl/L 1 . The LD 50 values for S. oryzae C. chinensis and T. castaneum in contact toxicity were 0.158, 0.140 and 0.208 mg/cm 2 , respectively. For grain treatment, a concentration of 500 mg/L 1 and 7 days exposure were needed to obtain 90 -100 % population extinction in all three insects. Probit analysis showed that C. chinensis were more susceptible than S. oryzae and T. castaneum. Gaschromatography-Mass Spectrometer (GCMS) studies for extracts indicated the presence of potent fumigant molecules in L. camara. The prospect of utilizing L. camara as potent fumigant insecticide is discussed.
