manufacture example 1

[0032] Production Example 1 Production of Motherwort Extract

[0033] 5 times the amount of petroleum ether was added to 100 g of motherwort, stirred and extracted at 50°C for 1 hour, filtered to obtain a petroleum ether extract, and after the petroleum ether extract was evaporated, about 0.5 g of a petroleum ether extract of the motherwort was obtained.

manufacture example 2

[0034] Production example 2 Production of yam extract

[0035] Substituting 100 g of Motherwort of Production Example 1 with 100 g of yam, extraction was performed in the same way to obtain a petroleum ether extract of yam, and after the petroleum ether extract was evaporated, about 0.3 g of petroleum ether extract of yam was obtained.

[0038] Manufacturing example

[0039]

[0040] Normal human epidermal keratinocytes (NHEK(F)) were cultured in EpiLife-KG2 (KURABO company) 6-well plates, and cultured until they became confluent. After that, it was changed to EpiLife-KG2 (no growth factor added), and the test solution and control solution were added separately. After culturing for 3 days, cells were recovered from each well.

[0041]

[0042] The lipid was extracted from the recovered cells by the Bligh and Dyer method. After drying the extract with nitrogen, the portion redissolved in the chloroform / methanol mixture was prepared as a lipid sample. In addition, the protein quality is quantified by the BCA method.

[0043]

[0044] The extracted lipids were analyzed by thin layer chromatography (TLC). Expand twice in the horizontal direction with chloroform:methanol:acetic acid=190:9:1. Spray with copper sulfate coloring solution, bake on a hot pl...

Abstract

The invention provides a cosmetic or pharmaceutical product capable of recovering and maintaining the shielding function and the moisture-preserving function of the skin, in particular to a ceramide production accelerant or humectant using plants or extractives thereof, such as motherwort and yam as active components.

Description

Technical field [0001] The present invention relates to a ceramide production accelerator and a moisturizer that can increase ceramide and restore the barrier function and moisturizing function of the skin. Background technique [0002] Ceramide, one of the sphingolipids, is a trace amount of lipid in the whole organism, but it occupies more than half of the lipid in the stratum corneum, the outermost layer of the skin, and plays an important role in the skin's moisturizing mechanism and barrier mechanism . After the ceramide is secreted in epidermal cells, a lamella structure is constructed between cells in the stratum corneum to function. [0003] However, there are many reports that dry skin, rough skin, atopic dermatitis (atopic dermatitis), senile xerosis (senile xerosis), psoriasis and other skin diseases, the healthy metabolism of ceramide is hindered, keratin The amount of ceramide in the layer decreases, causing the skin's moisturizing function and barrier function to de...
