Description

Technical Field

[0001] The invention relates to the technical field of medicines, and in particular to a method for preparing a notoginseng flower fermentation liquid and application of the fermentation liquid in cosmetics. Background Art

[0002] Notoginseng flower, also known as Tianqi flower and Sanqi flower, is the flower bud of the Panax notoginseng (Burk.) FHChen plant, which is mainly planted in Yunnan and Guangxi. The root of Panax notoginseng has been used in traditional Chinese medicine for thousands of years, and has the effects of hemostasis, anti-inflammatory and analgesia. However, there are few separate records of notoginseng flower in ancient literature. As a by-product, notoginseng flower is mainly used in the food and health care fields in my country. Literature shows that notoginseng flower tea has a history of more than 400 years in China.

[0003] In recent years, the effective ingredients of various parts of Panax notoginseng have been gradually analyzed and developed. Studies have shown that Panax notoginseng flowers are rich in various flavonoids, saponins, polyphenols and other ingredients. It can be seen that Panax notoginseng flowers have great development potential and application value. At present, foreign research mainly focuses on the pharmacological activity of Panax notoginseng roots, and relatively less attention is paid to Panax notoginseng flowers. Domestic development of Panax notoginseng flowers mainly focuses on chemical component analysis, pharmacological activity research and extraction process optimization.

[0004] At present, the research on Panax notoginseng flower in the field of cosmetics has gradually increased in recent years, and some progress has been made. However, most of them adopt solvent extraction methods, which have certain safety risks, environmental pollution and active ingredient loss. The use of microbial fermentation technology can not only avoid the problems caused by the use of organic solvents, but also effectively improve the generation of active ingredients, and has broad application prospects. CN112608949B uses microbial fermentation to develop whitening active Panax notoginseng flower fermentation liquid, however, in the active ingredient enrichment process, it still relies on organic solvent purification, and the patent also has the disadvantage of a single active ingredient in the product. In addition, CN116832073B discloses a Panax notoginseng flower extract prepared by decoction, alcohol precipitation and fermentation combination, with a high content of total saponins and Rg3, showing good antioxidant effect, but the extraction process is relatively complicated, and is also limited to the extraction of specific active ingredients.

[0005] The above shows that the potential of other active ingredients in Panax notoginseng flower has not been fully developed. Therefore, developing a Panax notoginseng flower extract with simple process, safety and environmental protection and multiple skin care effects at the same time has great application potential. Summary of the invention

[0006] Based on this, the present invention provides a notoginseng flower fermentation liquid, which is obtained by fermenting the notoginseng flower with Lactobacillus plantarum.
