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 the Hemerocallis natural powder product is 97.22g / 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.

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 Hemerocallis natural powder product is 94.61g / 100g. Table 3 shows the composition of flavonoids in the Hemerocallis natural powder, and the percentage (%) is the mass percentage in the HPLC chromatogram.

Abstract

The invention discloses a preparation method for natural hemerocallis citrina powder with both anti-depression and sleeping promotion effects. In the method, hemerocallis citrina is used as a raw material, a mixed solvent of ethyl alcohol and glycerin is used as an extractant, specific natural flavones composition in the hemerocallis citrina can be efficiently extracted in a targeted manner, and dried powder can be finally prepared, wherein the mixed solvent comprises the following components according to volume fraction: 72-82% of ethyl alcohol, 0.5-1.5% of glycerin, and the balance of water. An animal experiment proves that the natural hemerocallis citrina powder provided by the invention has both anti-depression activity and sleeping promotion activity, has a unique relation between neural activity and dosage, is wide in adaptive range of neural activity, has significant broad-spectrum improvement effect on the relief of various discomfort caused by fast-paced and high-pressure life of modern people, has special natural hemerocallis citrina fragrance, is excellent in water solubility, can be eaten independently, and also can be used as a nutritional supplement.

Description

technical field [0001] The invention relates to a medicinal and edible dual-purpose plant and a preparation method thereof, in particular to a new technology for extracting active ingredients from daylily flowers, natural daylily powder with antidepressant and sleep-promoting effects, and a preparation method thereof. Background technique [0002] Hemerocallis citrina, also known as day lily, is a perennial herb of the genus Hemerocallis in the family Liliaceae. The flower buds of Hemerocallis are fresh, tender and nutritious, and can be eaten as dried vegetables. At the same time, folks often use Hemerocallis as medicine, thinking that it has the effect of removing heat and dredging stranguria, clearing heat and cooling blood, which can open the chest and widen the diaphragm, make people calm and free from depression. [0003] The huge pressure brought by the modern fast-paced life often leads to physical and mental exhaustion, leading to successive or simultaneous appeara...
