Abstract

The invention relates to a method for preparing a plant extract having the effect of removing dark eye circles. The method is characterized by comprising the following steps: A, respectively selectingfresh sophora japonica and coix seed, washing, drying, pulverizing, sieving, weighing sophora japonica powder and coix seed powder according to the mass ratio of 3:1 as a plant mixture; B, respectively weighing glycerin, isoprene glycol and betaine according to the mass ratio of 4:3:1, carrying out uniform magnetic stirring in a thermostat water bath of 30-50 DEG C, cooling to room temperature asan eutecticevaporate solvent; C, weighing the plant mixture and the eutecticevaporate solvent at a mass ratio of 1:2-6, mixing well, heating to 40-60 DEG C, extracting by ultrasonic vibration for 1-3h, and filtering to obtain the plant extract having the effect of removing dark eye circles. The plant extract having the effect of removing dark eye circles contains various high-content active ingredients such as rutin, isoquercetin, daphnin and coix seed fat, and has a remarkable effect of removing dark eye circles. In addition, the extraction rate of the method is higher.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a preparation method of a plant extract with the effect of removing dark circles. Background technique [0002] In recent years, with climate change, environmental pollution and accelerated pace of life, the incidence of dark circles as an eye skin problem has increased significantly, greatly affecting the daily life of consumers. The treatment methods for dark circles are divided into chemotherapy represented by high-concentration hydroquinone and physical therapy represented by laser treatment, but there are disadvantages such as painful treatment process and long recovery period. Therefore, how to relieve the symptoms of dark circles safely, effectively and without side effects has become a problem that people pay more and more attention to. [0003] Flavonoids, glycosides and other components in natural Chinese medicinal plants have anti-inflammatory, whitening and ...
