Abstract

The invention discloses a raw material composition of a skin external preparation. The composition includes, by weight, 10-90 parts of brasenia schreberi powder, 10-50 parts of radix glycyrrhizae, and 5-90 parts of white fungus. The invention also discloses a skin external preparation stock solution, which includes, by weight, 10-90 parts of an extract liquid of the brasenia schreberi, 10-50 parts of an extract liquid of the radix glycyrrhizae, and 5-90 parts of an extract liquid of the white fungus. The invention also discloses a method of preparing the skin external preparation stock solution, which includes the steps of: adding the brasenia schreberi powder, radix glycyrrhizae powder and white fungus powder in water, maintaining the temperature for 1-2 h at 60 DEG C and performing extraction for 0.5-2 h, wherein the temperature is not less than 60 DEG C during extraction, and centrifuging the extract to obtain a supernatant and filtering the supernatant, purifying the supernatant through a polyamide column, and concentrating the supernatant. The invention also discloses application of the stock solution in preparation of the skin external preparation. The skin external preparation employs easy-to-obtained raw materials, is low in cost, has quite excellent moisturizing, anti-oxidizing and free radical removal performances, is simple in preparation method and low in production cost, and is free of organic solvent, pigment and tanning.

Example Embodiment

[0058] Example 1

[0059] 1. Preparation of Brasenia powder: choose fresh Brasenia aquatica 1000g, wash with clean water, the volume is 1000ml, homogenizer 4000rpm, 30min, 60 ℃ spray drying to obtain Brasenia aquatica powder, standby.

[0060] 2 Extraction method of stock solution:

[0061] a 10g of Brasenia powder, 10g of licorice powder, and 10g of white fungus powder were added to 1200ml of pure water, swelled at 60°C for 1 hour, and then homogenized and extracted for 2 hours.

[0062] b Centrifuge (6000rpm, 10min), collect the supernatant, precipitate and extract again, and combine the supernatant.

[0063] c The supernatant was passed through a polyamide column and eluted with deionized water.

[0064] d Filtrate the effluent, filter with 200 mesh gauze, filter with filter paper, 5 micron filter membrane, ultrafiltration and concentrate to 20 times the dry sample weight and volume of 600ml, which is ready. The prepared stock solution is a transparent viscous solution, slightly opalescent and high viscosity.
