Abstract

The invention relates to the technical field of mosquito repellent products, in particular to plant mosquito repellent based on artemisia annuae oil. The artemisia annuae oil of the plant mosquito repellent serves as the effective constituent, the artemisia annuae oil is a remaining residue obtained when artemisinin is extracted from artemisia annuae, and the content of the artemisinin is lower than 1%. According to the plant mosquito repellent, the artemisia annuae oil which is the remaining residue obtained when the artemisinin is extracted from the artemisia annuae is sufficiently developed and utilized, and the plant mosquito repellent has the good mosquito repellent effect.

Description

technical field [0001] The invention relates to the technical field of plant mosquito repellent products, in particular to a plant mosquito repellent formula based on artemisia annua oil. Background technique [0002] Artemisia annua is the aerial part of Artemisia annua, a plant of Compositae, which has the functions of clearing away heat and relieving heat, removing steam, and antimalarial. Artemisinin, the main component of Artemisia annua, is a sesquiterpene lactone, which has the characteristics of high efficiency, quick effect, low toxicity and safety in the treatment of dangerous cerebral malaria. It is also the only new antimalarial drug that has been internationally recognized in my country so far. [0003] However, according to the research on the extract of Artemisia annua in the prior art, the main active ingredients still mostly involve artemisinin; the residue left after extracting artemisinin——artemisia annua oil is usually burned as fuel or buried as waste, ...
