Abstract

The invention discloses a method for preparing lipidosome microcapsule long-acting mosquito repellent paste from plant essential oil, which comprises the following steps: uniformly mixing p-menthane-3, 8-diol yellow oily matter and Cymbopogon winterianus oil according to a mass ratio of 2: 1,dissolving in absolute ethyl alcohol, and then adding sulfonated succinate castor oil and a polyethylene glycol (600) dilaurate emulsifier for ultrasonic emulsification to prepare a core material system; stirring soybean lecithin, cholesterol, sesbania gum, propylene glycol alginate and redispersible latex powder into a core material system, uniformly stirring, and removing a solvent to obtain a liposome membrane; and ultrasonically dispersing the liposome membrane into a PBS buffer solution system containing polyvinylpyrrolidone, filtering, collecting filtrate, and freeze-drying to form the mosquito repellent paste. Themosquito repellent paste prepared by the method has a good mosquito-repelling effect, has double effects of moistening skin, can well prevent essential oil from volatilizing, and has no toxic or side effect on human and environment; and the used materials and process can better meet the requirements of environmental protection and health.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method for preparing liposome microcapsule long-acting mosquito repellent ointment by using plant essential oil. Background technique [0002] The main components of lemon eucalyptus oil are citronellal, neoisopulegol, isopulegol, citronellol, citronellyl acetate, and β-caryophyllene; Java citronella oil mainly contains citronellal, citronella Leaf alcohol, β-citronellol and elemol and other ingredients have good analgesic, antispasmodic, antibacterial, and antioxidant capabilities. Most of the water phase in the lemon eucalyptus extraction process is directly discharged into the environment, and has not been rationally developed and utilized, resulting in a waste of resources. There is a certain content in it, and it has a good mosquito repellent effect, and has no toxic and side effects on people and the environment. [0003] Javanese Citronella Oil Contains Citronellal...
