Abstract

The invention relates to an orange peel essential oil with a fly eradication effect and application of the orange peel essential oil. The orange peel essential oil is prepared by the following steps:I, preparing orange peel powder; II, weighing the dried orange peel powder prepared in the step I, putting the dried orange peel powder into a conical flask, adding absolute ethyl alcohol into the conical flask, sealing the opening of the conical flask, putting the conical flask into an ultrasonic extractor, and performing ultrasonic assisted extraction; III, performing vacuum suction filtration;IV, performing rotary evaporation, namely connecting a round-bottom flask with a rotary evaporator, adjusting parameters, and starting evaporation to evaporate out ethanol; and V, after evaporation is completed, performing centrifugation by using a centrifuge, collecting supernate, and weighing the supernate, so as to obtain the organic peel essential oil. According to the technical scheme, organic peel is adopted as a raw material, an ultrasonic assisted ethanol extraction technique is adopted as an extraction process, and the extraction rate can be up to 9.3308%. The orange peel essential oil has a good fly eradication effect, the fly eradiation rate can be up to 60%, and the effect is remarkable.

Description

technical field [0001] The invention relates to the preparation of an essential oil of orange peel, in particular to an essential oil of orange peel with the effect of killing flies and an application thereof. Background technique [0002] At present, the main methods of extracting citrus essential oil are pressing, distillation, solvent extraction and supercritical fluid extraction. Among them, the most commonly used method is the steam distillation method. The steam distillation method refers to an extraction method in which medicinal materials containing volatile components are distilled together with water, and the volatile components are evaporated together with water vapor and condensed to obtain volatile components. The method is suitable for extracting volatile medicinal materials, which can be steam distilled without being destroyed, are stable in water, and hardly soluble or insoluble in water. Steam distillation can be divided into co-water distillation, steam di...
