Abstract

The invention discloses a preparation method of lipidosome containing a glycyrrhiza inflata root extract and madecassoside, and the method comprises the following steps: A, adding the glycyrrhiza inflata root extract into 1, 3-propylene glycol to obtain a dissolving solution A; B, adding water and the dissolving solution A into hydroxypropyl-beta-cyclodextrin, and performing stirring to obtain a glycyrrhiza inflate root extract / hydroxypropyl-beta-cyclodextrin inclusion compound aqueous solution; C, drying the aqueous solution of the glycyrrhiza inflata root extract / hydroxypropyl-beta-cyclodextrin inclusion compound to obtain a glycyrrhiza inflata root extract / hydroxypropyl-beta-cyclodextrin inclusion compound; D, adding lecithin and cholesterol into caprylic / capric triglyceride to obtain an oil phase; E, adding the glycyrrhiza inflata root extract / hydroxypropyl-beta-cyclodextrin inclusion compound and madecassoside into water to obtain a water phase; F, adding the oil phase into the water phase, and homogenizing and circulating by using a high-pressure homogenizer to obtain the liposome containing the glycyrrhiza inflata root extract and madecassoside. The preparation method has the characteristic that the bioavailability can be effectively improved.

Description

technical field [0001] The invention relates to a preparation method of licorice root extract / cyclodextrin, in particular to a preparation method of liposome containing licorice root extract and madecassoside. Background technique [0002] Inflammation is an adaptive response produced by the body after being injured or harmful stimuli, and it is closely related to the occurrence and development of many diseases. Skin inflammation is one of the common inflammatory problems. The skin is an important protective layer to protect the human body from external damage and stimuli. When external stimuli cause damage to the human body, the immune system of the skin will initiate signals to promote inflammatory factors such as arachidonic acid. ﹑The overexpression of interleukin and other inflammatory factors and histamine causes blood flow to accelerate and cell permeability to increase, leading to symptoms such as skin tightness and redness, itching, desquamation, and even burning an...
