"Gold" Pressed Essential Oil: An Essay on the Volatile Fragment from Citrus Juice Industry By-Products Chemistry and Bioactivity.

摘要: Present essay explores the potentials of Citrus juice industry's by-products as alternative bioactive natural products resources. Four crude Cold Pressed Essential Oils (CPEOs), derived from orange, lemon, grapefruit, and mandarin, were studied. All CPEOs subjected to water distillation, in order obtain volatile fragment, which was further fractionated with respect distillation period two parts, concluding eight samples. These samples along four original assessed relation their phytochemical content repellent larvicidal properties against Asian Tiger Mosquito. The volatiles recovery rates ranged 74% 88% CPEO. Limonene presented a significant increase all ranging 8% 52% respective CPEO's peaked mandarin's 2nd fragment comprised 97% essential oil. refinement process clear impacts on both bioassays: potency observed, annotated best by improvement 1100% 1300% grapefruit fractions; repellence testing provided only one result, decrease landings 50% response second fraction. applied methodology thus may be considered for chemistry bioactivity.
