Abstract

The invention discloses an extraction method of cedar oil, and a cedar oil anophelifuge prepared from the cedar oil, relating to the technical field of biological medicines. The extraction method of the cedar oil comprises the following steps of A. preparation of materials; B. soaking; C. enzymolysis, and D. extraction. The cedar oil anophelifuge is prepared from the following raw materials: cedar oil, rosemary essential oil, a surfactant, a stabilizer, and the balance of water. The cedar oil anophelifuge has the characteristics of higher extraction rate of the cedar oil and capabilities of killing mosquitos effectively, restraining bacteria in air, purifying the air and the like; the cedar oil prepared by the method can be used as both medicinal raw materials and chemical raw materials; the cedar oil anophelifuge prepared from the cedar oil is suitable for indoor use in household in urban and rural and public places.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a cedar oil extraction method and a cedar oil mosquito repellent. Background technique [0002] Cedrus Cedrus deodara (Roxb) G.Don is a general term for Cedrus Trew species of Pianaceae plant Cedrus genus. It is widely distributed in various parts of my country. Cedar pine needles and pine branches contain cedar oil. At present, the extraction of cedar oil has methods such as distillation and extraction; most of the extraction methods use absolute ethanol, ethyl acetate, and petroleum ether as solvents, and adopt fractional extraction. [0003] The bites of mosquitoes, fleas, and bedbugs often cause symptoms such as itching and allergies, and also spread various diseases such as malaria, yellow fever, dengue fever, and AIDS, which seriously threaten human health. At the same time, mosquito bites can directly or indirectly bring pressure to human life, such as affecting sleep...
