Abstract

The invention belongs to the field of biological medicine and particularly relates to a mosquito-repellent composition and a preparation method thereof. The mosquito-repellent composition comprises, by weight, 80-160 parts of a wild mint extract, 60-160 parts of caraway essential oil, 60-120 parts of citronella essential oil, 30-80 parts of pelargonium graveolens essential oil, 30-80 parts of peppermint oil, 50-100 parts of acorus calamus essential oil, 20-60 parts of lavender essential oil and 40-120 parts of d-8-acetoxycarvotanacetone. The mosquito-repellent composition can prolong the mosquito-repellent protection time of d-8-acetoxycarvotanacetone for users. The composition can be applied to the production, research and development of related mosquito-repellent products.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to a mosquito repellent composition and a preparation method thereof. Background technique [0002] Mosquito bites have brought about the spread of various viruses and diseases, which have caused great harm to people's lives and health. Mosquito repellants are chemical agents that are applied to the skin or clothing to prevent mosquito bites and harassment. The repellent drug itself has no insecticidal effect, but has a volatile odor, which makes insects afraid to approach after smelling it. Currently, the existing repellent drugs are DEET, DEET-ketone, DEET alcohol, DEET and so on. In the study of natural plant repellent components, Chinese researchers have discovered a variety of natural substances with repellent activity, such as d-8-acetoxy allodihydrocarvone. d-8-Acetoxy allodihydrocarvone is an active ingredient extracted from Lamiaceae plants such as wild mint (Mentha...
