Al-Ansari, Mysoon M. published the artcileInsecticidal, antimicrobial and antioxidant activities of essential oil from Lavandula latifolia L. and its deterrent effects on Euphoria leucographa, Application of rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Euphoria Lavandula essential oil insecticide antimicrobial antioxidant.
Lavandula latifolia L. is a medicinal plant has fungicidal, antibacterial and antioxidant properties. The aim of this study was to determine the chem. composition, antioxidant and antimicrobial activities of essential oil (EO) of L. latifolia L. extracted by hydrodistillation method. A total of 22 constituents were identified in L. latifolia L. using Gas chromatog.-mass spectrometry anal. The compounds such as, gamma-terpinene (26.8%), camphor (13.8%), 1,8-cineole (10.2%), lavandulol (9.3%), terpinen-4-ol (9.1%), linalool (8.9%), b-elemene (3.2%), b-pinene (3.1%), 1,4-cineole (3.07%), camphene (2.32%), a-terpineol (2.3%), and a-copaene (2.2%) were determined The antifungal activity of this EO against five phytopathogenic fungi revealed their broad-spectrum and strong antifungal properties. Notably, the EO showed potent activity on Trichophyton mentagrophytes (31 ± 1 mm) and the min. inhibitory concentration value was 0.125 ± 0.05μg/mL. The oil, analyzed for its DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS [2,2_-azinobis-(3-ethylbenzothiazoline-6- sulfonic acid)] free radical scavenging activity. Hydrodistd. EO had higher ABTS scavenging capacity than DPPH free radical scavenging power. Essential oil was used to test pesticide activity against Euphoria leucographa (Order: Coleoptera; Family: Scarabaeidae) infected in custard apple (Annona muricata) fruit. Results indicated that the spike lavender EO had contact toxicity on E. leucographa upon topical treatment. The effective concentration at 50% (EC50) value of EC of L. latifolia L. was 0.37% revealed considerable fumigant activity mainly due to the presence of fragrant compounds Interestingly, custard apple (A. muricata) treated with EO effectively controlled the growth of T. mentagrophytes. Overall, antifungal and insecticidal properties of lavender EO, as a natural choice to preserve the harvested fruits thereby protecting the industrial crops.
Industrial Crops and Products published new progress about Annona muricata. 124-76-5 belongs to class alcohols-buliding-blocks, name is rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, and the molecular formula is C10H18O, Application of rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol.
