Embodiment 1

[0029] Example 1 Preparation of Salvia Miltiorrhiza Extract Processed Through Honey Roasting (Far Infrared Heating Method)

[0030] Add 1.5 kg of honey to 5 kg of Danshen slices, place them in a far-infrared oven, keep the temperature at 40°C for 50 minutes, heat the slices of Salvia miltiorrhiza at 100°C for 40 minutes, and then cool them down to room temperature quickly. Under the stirring state, use 10kg of water at 40°C to extract the cooled Danshen slices, extract twice, combine the extracts, concentrate under reduced pressure to one-tenth of the original volume, filter with suction, remove the precipitated filter residue, and freeze-dry the filtrate to obtain Honey-roasted Danshen extract powder.

Embodiment 2

[0031] Example 2 Preparation of Sophora japonica extract processed through honey roasting (microwave heating method)

[0032] Add 500g of honey to 1kg of dried Sophora japonica, mix well, put it in a microwave oven, heat at 200W for 3min, take it out and mix well, heat at 700W for 2min, take it out and cool it to room temperature; under stirring, use 2kg Extract the cooled Sophora japonica with water at 40°C, extract twice, combine the extracts, concentrate under reduced pressure to one-tenth of the original volume, then filter with suction to remove the precipitated filter residue, freeze-dry the filtrate to obtain Sophora japonica processed with honey Extract powder.

Embodiment 3

[0033] Example 3 Preparation of Salvia Miltiorrhiza Extract Processed Through Honey Roasting (Microwave Heating Method)

[0034] Add 500g of honey to 1kg of Salvia miltiorrhiza slices, mix well, place in a microwave oven, heat at 200W for 3 minutes, take it out and mix well, heat at 700W for 2 minutes, take it out and cool to room temperature; under stirring, use 2kg of water Extract the cooled Danshen slices at 40°C, extract twice, combine the extracts, concentrate under reduced pressure to one-tenth of the original volume, then filter with suction to remove the precipitated filter residue, freeze-dry the filtrate to obtain the honey-roasted Danshen extract powder.

Abstract

The invention discloses a composition for preventing and repairing skin injuries. The composition contains a flos sophorae extract baked with honey and / or a salvia extract baked with honey as the active component, wherein the weight ratio of the flos sophorae extract baked with honey and the salvia extract baked with honey is 1:(1-10). The composition provided by the invention contains the flos sophorae extract and the salvia extract or a mixture of the two to block skin oxidation reaction induced by ultraviolet rays or other harmful environmental factors so as to prevent melanin generation of skins, thereby taking the skin whitening effect.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a composition for preventing and repairing skin damage. Background technique [0002] The active oxygen generated after various physical and chemical factors in the environment act on cells can cause non-selective and irreversible damage to cells, thereby causing cell aging or cancer, and further leading to various diseases. Especially the lipid peroxidation caused by these reactive oxygen species, the generated lipid peroxide will oxidize the cells and destroy the physiological functions of the cells. Therefore, many antioxidants such as free radical scavengers or peroxide generation inhibitors are currently used to prevent or treat cell or tissue aging caused by these peroxides. [0003] Among these environmental factors, UV damage is particularly significant. Ultraviolet rays can be divided into long-wavelength ultraviolet rays (UV-A) longer than 320nm, medium-wavelength ultravi...
