Preparation method and application of selaginella fermentation extract

Abstract

The invention discloses a selaginella fermentation extract, a preparation method thereof, and an application thereof in skin care cosmetics. The raw materials of the selaginella fermentation extract comprise a fermentation system composed of selaginella, glucose, casein, vitamin C and water, and a seed bacterial liquid, wherein the seed bacterial liquid comprises sodium acetate, soybean peptone, glucose, yeast extract, dipotassium hydrogen phosphate, magnesium sulfate, manganese sulfate, distilled water and lactobacillus buchneri. The preparation method is as follows: separately preparing theseed bacterial liquid and the fermentation system; diluting the seed bacterial liquid, then performing inoculation into the fermentation system, and performing standing fermentation; and filtering anobtained fermentation material, separating a liquid phase part from a solid phase part, conducting micro-filtering on the liquid phase part to remove the bacteria, then adding a polyhydric alcohol, and adjusting the pH value to obtain the selaginella fermentation extract. The method uses the natural plant raw materials, probiotic fermentation is supplemented, the degrading effect of the bacterialmetabolic process to macromolecular compounds is fully utilized to prepare the extract with effects such as supplementing water and moisturizing, repairing the basement, and regulating skin micro-ecology.

Description

technical field

[0001] The invention relates to a method for extracting highly active cell lysates from Selaginella by fermentation, in particular to a method for preparing an extract by fermenting Selaginella with probiotics, and belongs to the field of biotechnology. Background technique

[0002] Selaginella is a native or stone recovery plant, the whole grass is cushion-shaped, and the content of trehalose is about 0.14%, so it has a strong ability to tolerate drought. It can survive under the physiological conditions of dehydration of more than 95% and recover quickly when it encounters water. The content of flavonoids in the whole plant is about 0.42%, so it has the effects of hemostasis, convergence, anti-inflammation and skin repair. And the dry leaves of Selaginella are rich in polysaccharides, amino acids, proteins, and flavonoids, which are natural skin care factors, and have strong moisturizing and antioxidant effects.
