The application relates to a preparation method of a bifendate from a medicine material source of Taxodium, which comprises the following steps of medicine material extraction, macroporous adsorption resin column chromatography and solid-liquid extraction. According to the acid property of the phenolic hydroxyl group of the bifendate, the extraction method of alkali extraction and acid precipitation is used to obtain an extract rich in the bifendate, then the macroporous adsorption resin process is combined with the solid-liquid extraction process to purify the extract, and finally the bifendate with the purity of more than 98% is obtained, and the yield can reach 1.319%. The application reduces the use of organic solvents, greatly simplifies the extraction and separation and purification process, is easy to scale up, and has the advantages of simple operation, low cost and high yield.

The invention relates to the technical field of traditional Chinese medicines, in particular to a selaginella tamariscina extract and a green extraction and purification method thereof. The green purification method comprises the following steps: extracting selaginella tamariscina to obtain a selaginella tamariscina Centrifuging the selaginella tamariscina extracting solution, passing through a micro-filtration membrane, passing through a macroporous resin column, and carrying out enzymolysis to obtain a purified extracting solution; and concentrating the purified extracting solution, and freeze-drying to obtain the traditional Chinese medicine composition. According to the method disclosed by the invention, the total flavone content and amentoflavone in the extract are improved to a certain extent, the antioxidant activity is stronger, the whole process is a green process chain, the solvent recovery rate is more than or equal to 90%, and the method is suitable for industrial continuous production.

The invention provides an application of a grease composition containing safflower seed oil, fermented artemisia apiacea oil and selaginella oil in post-medical repair. The fermented artemisia apiacea oil is prepared by the following steps: (a) carrying out supercritical CO2 extraction on artemisia apiacea medicinal materials; (b) fermenting, namely fermenting by adopting bifidus yeast; (c) separating to obtain fermented artemisia apiacea oil; wherein the bifidobacterium is selected from bifidobacterium adolescentis, bifidobacterium animalis subspecies, bifidobacterium animalis subspecies lactis, bifidobacterium bifidum, bifidobacterium breve, bifidobacterium longum subspecies longum or bifidobacterium longum subspecies infantis. The medical art is caused by dot matrix laser. The invention further relates to application of the grease composition containing the safflower seed oil, the fermented artemisia apiacea oil and the selaginella oil in preparation of an external skin preparation with a post-medical repair effect.

The invention relates to a sensitive skin anti-aging composition containing arenaria kansuensis callus extract as well as a preparation method and application of the sensitive skin anti-aging composition, and belongs to the technical field of cosmetics. The sensitive skin anti-aging composition comprises an arenaria kansuensis callus extract, phytosphingosine, a selaginella tamariscina extract and a hydrolyzed gardenia extract. According to the preparation method, the selaginella tamariscina extract is prepared by adopting a supramolecular extraction technology, so that the active substances of the selaginella tamariscina extract are mildly and efficiently enriched, and the biocompatibility and the transdermal penetration capacity of the extract are remarkably improved. When the arenaria kansuensis callus extract is compounded with the phytosphingosine, the selaginella tamariscina extract and the hydrolyzed gardenia extract, a synergistic effect can be generated, and systematic intervention is performed on a complex skin aging network from four aspects of energy metabolism, barrier repair, cell protection and inflammation regulation; the invention provides a complete technical scheme with mild characteristic and multi-dimensional anti-aging effect for people with sensitive skin.
