Abstract : Essential oils of Salvia macrochlamys and Salvia recognita were obtained by hydrodistillation of dried aerial parts and characterized by gas chromatography and gas chromatography-mass spectrometry. One hundred and twenty identified constituents representing 97.7% in S. macrochlamys and 96.4% in S. recognita were characterized, and 1,8-cineole, borneol, and camphor were identified as major components of the essential oils. The oils were evaluated for their antimalarial, antimicrobial, and antifungal activities. Antifungal activity of the essential oils from both Salvia species was nonselective at inhibiting growth and development of reproductive stroma of the plant pathogens Colletotrichum acutatum, Colletotrichum fragariae, and Colletotrichum gloeosporioides. S. macrochlamys oil had good antimycobacterial activity against Mycobacterium intracellulare; however, the oils showed no antimicrobial activity against human pathogenic bacteria or fungi up to a concentration of 200 microg/mL. S. recognita oil exhibited a weak antimalarial activity against Plasmodium falciparum.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae.

Volume : 51
Issue : 6

Authors : Kim MK, Choi GJ, Lee HS.
Abstract : Fungicidal activity of Curcuma longa rhizome-derived materials against Botrytis cineria, Erysiphe graminis, Phytophthora infestans, Puccinia recondita, Pyricularia oryzae, and Rhizoctonia solani was tested using a whole plant method in vivo. It was compared with synthetic fungicides and four commercially available compounds derived from C. longa. The response varied with the tested plant pathogen. At 1000 mg/L, the hexane extract of C. longa showed fungicidal activities against E.graminis, P. infestans, and R. solani, and the ethyl acetate extract of C. longa showed fungicidal activities against B. cineria, P. infestans, Pu. recondita, and R. solani. Curcumin was isolated from the ethyl acetate fraction using chromatographic techniques and showed fungicidal activities against P. infestans, Pu. recondita, and R. solani with 100, 100, and 63% control values at 500 mg/L and 85, 76, and 45% control values at 250 mg/L, respectively. In the test with components derived from C. longa, turmerone exhibited weak activity against E. graminis, but no activity was observed from treatments with borneol, 1,8-cineole, sabinene, and turmerone. In comparison, potent fungicidal activity with chlorothalonil against P. infestans at 50 mg/L and dichlofluanid against B. cinerea at 50 mg/L was exhibited. These results may be an indication of at least one of the fungicidal actions of curcumin derived from C. longa.

Abstract : Fungicidal activity of Curcuma longa rhizome-derived materials against Botrytis cineria, Erysiphe graminis, Phytophthora infestans, Puccinia recondita, Pyricularia oryzae, and Rhizoctonia solani was tested using a whole plant method in vivo. It was compared with synthetic fungicides and four commercially available compounds derived from C. longa. The response varied with the tested plant pathogen. At 1000 mg/L, the hexane extract of C. longa showed fungicidal activities against E.graminis, P. infestans, and R. solani, and the ethyl acetate extract of C. longa showed fungicidal activities against B. cineria, P. infestans, Pu. recondita, and R. solani. Curcumin was isolated from the ethyl acetate fraction using chromatographic techniques and showed fungicidal activities against P. infestans, Pu. recondita, and R. solani with 100, 100, and 63% control values at 500 mg/L and 85, 76, and 45% control values at 250 mg/L, respectively. In the test with components derived from C. longa, turmerone exhibited weak activity against E. graminis, but no activity was observed from treatments with borneol, 1,8-cineole, sabinene, and turmerone. In comparison, potent fungicidal activity with chlorothalonil against P. infestans at 50 mg/L and dichlofluanid against B. cinerea at 50 mg/L was exhibited. These results may be an indication of at least one of the fungicidal actions of curcumin derived from C. longa.

Abstract : The chemical composition of the essential oil of the Sardinian Rosmarinus officinalis L. obtained by hydro distillation and steam\hydro distillation was studied using GC-FID and MS. Samples were collected at different latitude and longitude of Sardinia (Italy). The yields ranged between 1.75 and 0.48% (v/w, volume/dry-weight). A total of 30 components were identified. The major compounds in the essential oil were alpha-pinene, borneol, (-) camphene, camphor, verbenone, and bornyl-acetate. Multivariate analysis carried out on chemical molecular markers, with the appraisal of chemical, pedological, and random amplified polymorphic DNA data, allows four different clusters to be distinguished. The antimicrobial and antifungal tests showed a weak activity of Sardinian rosemary. On the other hand, an inductive effect on fungal growth, especially toward Fusarium graminearum was observed.

Title : Fumigant toxicity of lemon eucalyptus oil constituents to acaricide-susceptible and acaricide-resistant Tetranychus urticae.

Abstract : BACKGROUND: This study was aimed at assessing the fumigant toxicity of 14 essential oil constituents from lemon eucalyptus, Eucalyptus citriodora Hook, and another ten known compounds to females of acaricide-susceptible, chlorfenapyr-resistant, fenpropathrin-resistant, pyridaben-resistant and abamectin-resistant strains of Tetranychus urticae Koch. RESULTS: Menthol (LC(50) , 12.9 µg cm(-3) ) was the most toxic compound, followed by citronellyl acetate (16.8 µg cm(-3) ), against the susceptible females. High toxicity was also produced by β-citronellol, citral, geranyl acetate and eugenol (LC(50) , 21.7-24.6 µg cm(-3) ). The fumigant toxicity of these compounds was almost identical against females from either of the susceptible and resistant strains, indicating that the compounds and acaricides do not share a common mode of action or elicit cross-resistance. CONCLUSION: Global efforts to reduce the level of highly toxic synthetic acaricides in the agricultural environment justify further studies on materials derived from lemon eucalyptus oil, particularly menthol and citronellyl acetate, as potential acaricides for the control of acaricide-resistant T. urticae as fumigants with contact action.
