Caputo, Lucia published the artcileChemical composition and biological activities of essential oils from peels of three Citrus species, Name: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Citrus fruit peelessential oil chem composition phototoxicity biol activity; Citrus limon; Citrus × bergamia; Citrus × myrtifolia; eco-compatibility; essential oil; phytotoxicity.
Fruit peels are generally underutilized byproducts of the food industry, although they are valuable sources of bioactive compounds The aim of this study is to evaluate a new application for three Citrus peel EOs as bio-herbicides. After a micro-morphol. evaluation of Citrus peels by SEM anal., the phytochem. composition of the EOs of Citrus x bergamia Risso & Poit., Citrus x myrtifolia Raf., and Citruslimon (L.) Osbeck was characterized by GC/FID and GC/MS analyses. The in vitro phytotoxicity against germination and initial radical elongation of several crop and weed species was evaluated. Furthermore, the eco-compatibility of these EOs has been assessed by the brine shrimp (Artemia salina) lethality assay. SEM anal. highlighted the morphometric differences of the schizolysigenous pockets among the peels of the three Citrus species. Oxygenated monoterpenes are the main constituents in C. x bergamia (51.09%), whereas monoterpene hydrocarbons represent the most abundant compounds in C. x myrtifolia (82.15%) and C. limon (80.33%) EOs. They showed marked and selective phytotoxic activity in vitro, often at very low concentration (0.1 μg/mL) against all plant species investigated, without showing any toxicity on Artemia salina, opening the perspective of their use as safe bio-herbicides.
Molecules published new progress about Artemia salina. 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, Name: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol.
