The invention provides a quinoa flavone extracting solution as well as a preparation method and application thereof, and belongs to the technical field of natural plant extraction. The preparation method of the quinoa flavone extracting solution provided by the invention comprises the following steps: mixing quinoa, compound enzyme and water to obtain a mixed solution; performing ultrasonic treatment on the mixed solution to obtain a quinoa flavone extracting solution; the compound enzyme comprises cellulase and pectinase. According to the method, the flavone in the chenopodium quinoa willd is extracted by adopting ultrasonic-compound enzyme synergistically, so that the method has the characteristics of high yield, short extraction time, low energy consumption, large raw material treatment capacity, low possibility of damaging active substances, environmental friendliness, reduction of environmental pollution and the like, the comprehensive utilization of the chenopodium quinoa willd can be enhanced, and the additional value of the chenopodium quinoa willd can be improved.

The invention discloses application of two small molecular substances in regulation and control of weed suppression activity of flavonoid glycoside substances. The invention provides any one of the following applications of a GST activator and a GST inhibitor: (A1) regulating the inhibition activity of wheat flavone-5-O-glucoside to weeds; and (A2) the inhibition activity of the isoorientin on weeds is regulated. According to the invention, the weed suppression effect of the flavonoid glycoside substances can be obviously improved, and the use of chemical pesticides is reduced, so that a novel biological control method is provided for agricultural production, and green agriculture and sustainable development can be realized.

The invention relates to the technical field of fermentation engineering and medicines, and discloses a high-yield production method of hispidulin, which comprises the following steps: (1) preparing a nutrient solution, (2) preparing a solid fermentation conversion culture medium, (3) directionally converting solid fermentation, and (4) extracting hispidulin. According to the method, a powerful enzyme system of schizophyllum commune is utilized to perform biotransformation on the traditional Chinese medicine scutellaria baicalensis which is extremely low in homoplantaginin content (or cannot be detected), so that oriented biotransformation of the homoplantaginin of main flavone in scutellaria baicalensis flavone is realized, and high-yield production of the homoplantaginin is realized. The method has the characteristics of high hispidulin directional conversion efficiency, simple operation, cheap raw materials and the like, provides a new technology and a new method for research and development of new hispidulin-containing medicines, functional foods and cosmetics, and has important application prospects and remarkable economic benefits.

The application discloses a flavonoid carbon glycoside compound, a directional separation and preparation method and application thereof. The flavonoid carbon glycoside compound is first extracted and discovered, and is used for preparing a medicine for treating or improving diabetes. The preparation process comprises the following steps: extraction, microporous resin medium pressure chromatography rough separation, reverse phase medium pressure chromatography enrichment, reverse phase preparation column preparation, Fr411 reverse phase preparation liquid chromatography purification, and Fr412 hydrophilic preparation liquid chromatography purification.
