Embodiment 1

[0188] Embodiment 1: Preparation of Huanghua Qijingu Extract

[0189] Auntia chinensis was collected and prepared into a 1:5 water infusion solution, wherein 200 mg of anhydrous plant material obtained 1 ml of extract. The leachate is a solvent-free aqueous preparation.

Embodiment 2

[0190] Example 2: Preparation of Yeast / Chrysanthemum chinensis fermented extract

[0191] Acanthus fragrans extract, as described above, was fermented with standard Pichia pastoris fermentation medium for a period of 72-140 hours until plant components were at least partially metabolized as assessed by optical density measurements. Crude Yeast / C. chinensis extract was dissolved and ground to release water-soluble cell wall components, including polysaccharides. Insoluble components were removed by filtration in order to improve color and odor. Save the final liquid fermented extract product.

Embodiment 3

[0192] Example 3: Tissue Culture of Fibroblasts

[0193] Adult human dermal fibroblasts (22 years old; Cascade; #5C0759) were grown in fibroblast growth medium containing 10% FBS, 1% L-glutamine and 1% P / S. Fibroblasts were seeded on 6-well culture plates at a density of 350,000 cells / well and cultured overnight. Remove supernatant from each well. Serum-free medium (1% L-glutamine, 1% P / S, and no FBS) containing medium or yeast / A. chinensis ferment extract was added to the cells. Forty-eight hours after treatment, cell lysates were collected.
