A highly efficient method for catalyzing the synthesis of sanguinarine and chelerythrine, comprising: from the known protopine-6-hydroxylase gene, dihydrobenzophenanthridine oxidase gene and cytochrome P450 reductase gene, by means of heterologous expression and result comparison and analysis, screening out an optimal gene having high expression efficiency, then performing codon optimization on the selected optimal gene; constructing the optimal gene sequence on an expression vector, then transferring same into yeast engineering bacteria for transformation so as to obtain recombinant yeast engineering strains; finally, feeding the recombinant yeast engineering bacteria by using a leaf raw material liquid precursor of Macleaya cordata for fermentation, so as to obtain a product. The invention improves the enzyme catalytic efficiency of sanguinarine and chelerythrine in various aspects such as gene level and fermentation process; the leaf raw material liquid, which is not a traditional medicinal part of Macleaya cordata, is directly used for fermentation with the engineering bacteria, and protopine and allocryptine having high alkaloid content in leaves are converted into high-value sanguinarine and chelerythrine to achieve the comprehensive utilization of Macleaya cordata resources.

A chelerythrine suspension agent and a preparation method and application thereof belong to the technical field of vegetable biological pesticides. In order to find an environmentally friendly, low-toxic and efficient control method for rice flax spot disease, the celandine original drug, dispersant Atlox49134%, wetting agent GenapolX0802%, glycerol 5%, magnesium aluminum silicate 0.5%, Xanthan gum 0.1%, Sag15220.2% and deionized water are compounded, and a suspending agent with fine particle size, high suspension rate and no dust is obtained by mixing, shearing and grinding. The suspending agent is used in the prevention and treatment of rice flax spot disease, showing good control effect, and has the advantages of high efficiency, low toxicity, no pollution, easy degradation and no environmental pollution, which is in line with the development of green food and sustainable agricultural development. need.

The invention discloses a making method of polyphenylacetylene typed adsorption resin with high-polarity group and application to bocconine alkaloid, which is characterized by the following: synthesizing new-typed adsorption resin based on polyphenylacetylene as frame with high-polarity group content according to structural feature of sanguinarine and toddaline; utilizing the synergic effect of resin dipole action and hydrophobic action; separating sanguinarine and toddaline from resin.
