Embodiment 1

[0017] Embodiment 1: the preparation of black lotus essential oil

[0018] Weigh 50g of pulverized Eclipta powder that has passed through a 40-mesh sieve, add 1000ml of ultrapure water and mix. Keep a slight boil for 4h in the simultaneous evaporation and extraction experimental device. The organic solvent was obtained by layering, and the organic solvent was evaporated in vacuum to obtain Eclipta essential oil. Repeat the operation to accumulate the extracted amount of essential oil for later use.

Embodiment 2

[0020] Mix 15g of Eclipta essential oil with 25g of alcohol and stir evenly, add 2g of natural essence and 58g of distilled water and mix evenly to obtain a slightly yellow clear liquid, that is, mosquito repellent water containing herbal essential oil components.

Embodiment 3

[0022] Mix 25g of Eclipta essential oil with 35g of alcohol and stir evenly, add 5g of natural essence and 35g of distilled water and mix evenly to obtain a slightly yellow clear liquid, that is, mosquito repellent water containing herbal essential oil components.

Abstract

The invention belongs to the field of natural medicines and discloses mosquito repellent liquid containing herbaceous plant essential oil components as well as a preparation method and application thereof. The mosquito repellent liquid contains 15wt%-25wt% of herba ecliptae essential oil, 25wt%-35wt% of alcohol, 2wt%-5wt% of natural essence and the balance of distilled water. Mosquito-resisting effective substances of the mosquito repellent liquid are mainly extracted from herba ecliptae; the herba ecliptae is picked, washed, dried with air and crushed and sieved with a 40-mesh sieve and then is treated by an evaporation and extraction method to prepare the extract. The invention aims at researching efficient and low-toxin plant source type insecticides for meeting the requirements on green chemistry of modern people.
