Embodiment 1
[0025] Embodiment 1 A kind of preparation method of flower wax, honey, flavonoid part of the by-product of hollyhock flower pharmaceutical process, comprises the following steps:
[0026] (1) press figure 1 As shown in the process flow, take 2kg of by-products in the production process of hollyhock flower preparations (after the hollyhock flower is extracted with ethanol, the obtained extract, the precipitate and suspended matter precipitated after cooling and concentration), add petroleum jelly at a solid-liquid weight ratio of 1:10 The ether was extracted twice, each time for 1 hour, and centrifuged to obtain the extract and residue respectively.
[0027] (2) Take the extract obtained in step (1), recover the solvent under reduced pressure to dryness, and obtain 500 g of flower wax.
[0028] (3) Take the residue obtained in step (1), suspend it with water, separate it by polyamide resin column chromatography, and elute it with water to obtain an eluent, which is concentrate...
Embodiment 2
[0031] Example 2 A method for preparing the wax, honey, and flavonoid parts of the by-products of the pharmaceutical process of hollyhock flower, comprising the following steps:
[0032] (1) press figure 1 As shown in the technological process, take 1 kg of the by-product of the production process of the hollyhock flower preparation (after the hollyhock flower is extracted with ethanol, the obtained extract, the precipitate and suspended matter precipitated after cooling and concentration), add acetonitrile at a solid-to-liquid weight ratio of 1:20 Extract with alkane twice, each time for 0.5 hours, and filter to obtain the extract and residue respectively.
[0033] (2) Take the extract obtained in step (1), recover the solvent under reduced pressure to dryness, and obtain 240 g of flower wax.
[0034] (3) Take the residue obtained in step (1), suspend it with water, separate it through polyamide resin column chromatography, and elute with 5% ethanol to obtain an eluent, whic...
Embodiment 3
[0037] Example 3 A method for preparing the wax, honey, and flavonoid parts of the by-products of the pharmaceutical process of hollyhock flower, comprising the following steps:
[0038] (1) press figure 1 As shown in the process flow, take 2 kg of the by-product of the production process of hollyhock flower preparation (after the hollyhock flower is extracted with ethanol, the obtained extract, the precipitate and suspended matter precipitated after cooling and concentration), add gasoline according to the solid-liquid weight ratio of 1:15 Extract with ether for 2 hours and filter to obtain extract and residue respectively.
[0039] (2) Take the extract obtained in step (1), recover the solvent under reduced pressure until dry, and obtain 440 g of dry paste.
[0040](3) Take the residue obtained in step (1), suspend it with water, separate it through polyamide resin column chromatography, and elute it with 10% ethanol to obtain an eluent, which is concentrated to dryness to ...
