Embodiment 1
[0042]Example 1: Activity comparison of Hemerocallis natural powder prepared by extracting Hemerocallis flowers with different extractants
[0043] (1) Hemerocallis flower crosses 80 mesh sieves after crushing, adds 5 kinds of mixed solvents of ethanol and glycerin respectively by the solid-liquid ratio of 1g:10ml 5 groups, and the volume fraction of ethanol in these 5 kinds of mixed solvents is respectively 0%, 25% %, 50%, 75% and 100%, the volume fraction of glycerin is 1%. Extract at 25°C for 12 hours to obtain 5 kinds of Hemerocallis flower extracts, filter the Hemerocallis flower extracts, extract the separated residues again according to the above method, and combine the obtained Hemerocallis flower extracts.
[0044] (2) The combined extracts of Hemerocallis flower were filtered, and the supernatant was concentrated under reduced pressure at 60°C and freeze-dried to prepare five kinds of Hemerocallis natural powders HCE0, HCE25, HCE50, HCE75 and HCE100, with yields of 1...
Embodiment 2
[0058] (1) Hemerocallis is crushed and passed through an 80-mesh sieve, and a mixed solvent of ethanol and glycerin is added at a solid-liquid ratio of 1g:10ml, wherein the volume fraction of ethanol is 75%, the volume fraction of glycerin is 1%, and the balance is water. Extract at 25° C. for 12 hours to obtain Hemerocallis flower extract, filter the Hemerocallis flower extract, extract the separated residues again according to the above method, and combine the obtained Hemerocallis flower extracts.
[0059] (2) The extract of Hemerocallis flower was filtered, and the supernatant was concentrated under reduced pressure at 60° C. and freeze-dried to obtain Hemerocallis natural powder with a yield of 13.7%.
[0060] The solubility of Hemerocallis natural powder product is 97.22g / 100g. Table 1 shows the composition of flavonoids in the Hemerocallis natural powder, and the percentage (%) is the mass percentage in the HPLC chromatogram.

Embodiment 3
[0064] (1) Hemerocallis flowers pass through 80 mesh sieves after crushing, add a mixed solvent of ethanol and glycerin at a solid-liquid ratio of 1g:10ml, wherein the volume fraction of ethanol is 72%, the volume fraction of glycerin is 0.5%, and the balance is water . Extract at 25°C for 12 hours to obtain Hemerocallis flower extract, filter the Hemerocallis flower extract; extract the separated dregs again according to the above method, and combine the obtained Hemerocallis flower extracts.
[0065] (2) The extract of Hemerocallis flower was filtered, and the supernatant was concentrated under reduced pressure at 60° C. and freeze-dried to prepare Hemerocallis natural powder with a yield of 9.4%.
[0066] The solubility of the Hemerocallis natural powder product is 94.61g / 100g, and Table 2 shows the composition of flavonoids in the Hemerocallis natural powder, wherein the percentage (%) is the mass percentage in the HPLC chromatogram.
