Embodiment 1

[0032] Determination of 3-(4'-Hydroxyphenyl)-5,7-dihydroxy-6-methyl-8-oxomethyl-phenylpropanedihydropyran-4 in Polygonatum Polygonatum Dihydrohomoisoflavone Extract by HPLC -ketone, 3-(4'-hydroxyphenyl)-5,7-dihydroxy-6,8-dimethyl-phenylpropanedihydropyran-4-one and 3-(4'-methoxyphenyl )-5,7-dihydroxy-6-methyl-8-oxymethyl-phenylpropanedihydropyran-4-one content method

[0033] Chromatographic conditions and system suitability test

[0034] Octadecylsilane bonded silica gel is used as filler; water is used as mobile phase A, methanol is used as mobile phase B, linear gradient elution: 0min (A 60%, B 40%)→10min (A 40%, B 60%)→30min(A 30%, B 70%)→40min(A 0%, B 100%); flow rate: 1.0mL min -1 ; The detection wavelength is 254nm. The number of theoretical plates is calculated based on the peak of 3-(4'-hydroxyphenyl)-5,7-dihydroxy-6,8-dimethyl-phenylpropanedihydropyran-4-one, not less than 4000.

Embodiment 2

[0043] Take 100Kg of Polygonatum rhizome powder, add 9 times the amount of ethanol to reflux and extract 3 times, each time for 2 hours, filter, combine the extracts, and recover the extract under reduced pressure. Take the extract and dissolve it in water, add it to HPD100 macroporous adsorption resin column, elute with water until the eluent is nearly colorless, discard the eluent, and elute with 50% ethanol until the eluent is nearly colorless, discard the eluent Remove the liquid, elute with ethanol until the eluate is nearly colorless, collect the eluate, and recover under reduced pressure to obtain 642 g of polygonatum dihydrohomoisoflavone extract. The method of Example 1 is used to measure 3-(4'-hydroxyphenyl)-5,7-dihydroxy-6-methyl-8-oxomethyl-phenylpropanedihydro in Polygonatum Polygonatum Dihydrogen-Isoflavone Extract Pyran-4-one, 3-(4'-hydroxyphenyl)-5,7-dihydroxy-6,8-dimethyl-phenylpropanedihydropyran-4-one and 3-(4'- The sum of the contents of methoxyphenyl)-5,7...

Embodiment 3

[0045] Take 100Kg of Polygonatum rhizome powder, add 12 times the amount of 90% ethanol to reflux and extract for 3 times, each time for 2 hours, filter, combine the extracts, and recover under reduced pressure to obtain the extract. Take the extract and dissolve it in water, add it to HPD200 macroporous adsorption resin column, elute with water until the eluent is nearly colorless, discard the eluent, and elute with 40% ethanol until the eluent is nearly colorless, discard the eluent Remove the liquid, elute with 90% ethanol until the eluate is nearly colorless, collect the eluate, and recover under reduced pressure to obtain 895 g of Polygonatum dihydrogenum isoflavone extract.

Abstract

The invention provides a fragrant solomonseal rhizome isoflavanone extract and a preparation method thereof. The fragrant solomonseal rhizome isoflavanone extract contains 3-(4'- hydroxyphenyl)-5,7-dyhydroxy-6-methyl-8-O-methylation-styrene acrylic dihydropyrane-4-ketone, 3-(4'-hydroxyphenyl)-5,7-dyhydroxy-6,8-dimethyl-styrene acrylic dihydropyrane-4-ketone and 3-(4'-methoxyphenyl)-5,7-dyhydroxy-6-methyl-8-O-methylation-styrene acrylic dihydropyrane-4-ketone, and the content sum of all components is larger than or equal to 15 percent. The invention also discloses an application of the fragrantsolomonseal rhizome isoflavanone extract in preparing a product for preventing and / or treating diabetic nephropathy and an application of a fragrant solomonseal rhizome isoflavanone compound containing the 3-(4'- hydroxyphenyl)-5,7-dyhydroxy-6-methyl-8-O-methylation-styrene acrylic dihydropyrane-4-ketone, the 3-(4'-hydroxyphenyl)-5,7-dyhydroxy-6,8-dimethyl-styrene acrylic dihydropyrane-4-ketone and the 3-(4'-methoxyphenyl)-5,7-dyhydroxy-6-methyl-8-O-methylation-styrene acrylic dihydropyrane-4-ketone in preparing an inhibitor product as a protein nonenzyme glycolysis end product.
