Embodiment 1

[0027] Take Panax notoginseng (decoction pieces, that is, dried Panax notoginseng, produced with reference to the "Local Food Safety Standard of Yunnan Province" DBS 53 / 023-2017), crush and pass through 40 meshes to obtain 1 kg of medicinal powder. Add the medicinal powder into the culture medium (obtain the pre-culture system), then sterilize with damp heat at 121°C and 0.1MPa for 30 minutes, and then carry out the fermentation of Saccharomyces cerevisiae (Saccharomyces cerevisiae, 18824) inoculation (need to cool the culture medium). Among them, the composition and content of the culture medium are: yeast extract 1.00g / L, peptone 3.0g / L, diammonium hydrogen citrate 1.3g / L, magnesium sulfate 0.40g / L, lactose 2.5g / L, manganese sulfate 0.15 g / L, ferric chloride 0.05g / L, calcium chloride 0.05g / L, dipotassium hydrogen phosphate 1.30g / L, sodium acetate 4.0g / L, Tween 80 0.7ml / L. The mass volume ratio of the medicinal powder and the culture solution is 1g:30ml, the inoculation amo...

Embodiment 2

[0029] Take notoginseng flower (decoction pieces), crush it and pass through 30 meshes to obtain medicinal powder. Add the medicinal powder into the culture medium (obtain the pre-culture system), then sterilize with damp heat at 121°C and 0.1MPa for 30 minutes, and then carry out the fermentation of Saccharomyces cerevisiae (Saccharomyces cerevisiae, 18824) inoculation (need to cool the culture medium). Among them, the composition and content of the culture solution are: yeast extract 0.75g / L, peptone 2.5g / L, diammonium hydrogen citrate 1.00g / L, magnesium sulfate 0.25g / L, lactose 2g / L, manganese sulfate 0.10g / L, ferric chloride 0.01g / L, calcium chloride 0.01g / L, dipotassium hydrogen phosphate 1.20g / L, sodium acetate 3.5g / L, Tween 80 0.5ml / L. The mass volume ratio of the medicinal powder and the culture solution is 1g:20ml, the inoculation amount of Saccharomyces cerevisiae is 4% (mass fraction of Saccharomyces cerevisiae in the culture system), and the culture system is ob...

Embodiment 3

[0031] Take Panax notoginseng flower (decoction pieces), crush it and pass through 50 meshes to obtain medicinal powder. Add the medicinal powder into the culture medium (obtain the pre-culture system), then sterilize with damp heat at 121°C and 0.1MPa for 30 minutes, and then carry out the fermentation of Saccharomyces cerevisiae (Saccharomyces cerevisiae, 18824) inoculation (need to cool the culture medium). Among them, the composition and content of the culture medium are: yeast extract 1.50g / L, peptone 3.5g / L, diammonium hydrogen citrate 1.50g / L, magnesium sulfate 0.50g / L, lactose 3g / L, manganese sulfate 0.20g / L, ferric chloride 0.10g / L, calcium chloride 0.08g / L, dipotassium hydrogen phosphate 1.50g / L, sodium acetate 4.5g / L, Tween 80 0.8ml / L. The mass volume ratio of the medicinal powder and the culture solution is 1g:40ml, the inoculation amount of Saccharomyces cerevisiae is 6% (mass fraction of Saccharomyces cerevisiae in the culture system), and the culture system is...

Abstract

The invention relates to the technical field of preparation of plant natural products, and particularly relates to a preparation method and application of a sanqi flower bud extract. The preparation method of the sanqi flower bud extract comprises an extraction step in which medicinal powder obtained by crushing sanqi flower buds is fermented by using saccharomyces cerevisiae to obtain fermentation liquor. According to the scheme, the technical problem that the sanqi flower bud extract is poor in whitening effect can be solved. The sanqi flower bud extract prepared by the scheme has the function of inhibiting tyrosinase activity, and can effectively inhibit the generation of melanin, thereby whitening the skin. Therefore, the sanqi flower bud extract obtained by the scheme can be used for preparing various types of whitening products, and the application range of the sanqi flower buds is further expanded.

Description

technical field [0001] The invention relates to the technical field of plant natural product preparation, in particular to a preparation method and application of a Panax notoginseng flower extract. Background technique [0002] Sanqi Flower (Sanqi Flower Buds) is the inflorescence of Panax notoginseng of Araliaceae. Panax notoginseng has a good hemostatic effect, promotes the division and growth of various blood cells, can significantly increase the number of red blood cells in the pathological model of hemorrhagic anemia, and has a good therapeutic effect on hemorrhagic anemia. In recent years, some research reports have shown that Panax notoginseng flower extract has whitening effect and can be used in the development of related whitening products. However, the research on ingredients with whitening effect in Panax notoginseng is not thorough enough, and the whitening effect of Panax notoginseng has not been fully explored and developed. The whitening effect of Panax no...
