[0004] However, the extraction and application of lily steroidal saponins in the existing patents are still very rough. Not only does the extract not completely remove impurities, oils and polysaccharides, it may cause human allergies, and the proportion of sleep-aiding ingredients is low, and the sleep-aiding efficiency is poor.

Embodiment 1
[0022] A preparation method of a lily vine for sleep aid non-woven fabric, comprising the steps of:
[0023] (1) The roots, stems and leaves of lily plants are used as raw materials, naturally air-dried and crushed, and extracted 4 times at 60-80°C with 70%-80% ethanol whose volume is 5-7 times the mass of lily, each time Extract for 2 hours, recover the solvent ethanol to obtain ethanol extract; suspend the ethanol extract in water, use water-saturated n-butanol to extract crude saponins, and then analyze by reversed-phase column chromatography and gel column chromatography and purify lily steroidal saponins to obtain natural lily steroidal saponin extracts with a purity ≥ 85%; the main material structure of lily steroidal saponin extracts includes (25R)-3β, 17α-dihydroxy-5α-spirosterane- 6-keto-3-O-α-L-rhamnosyl-(1→2)-β-D-glucoside and (25R)-3β-hydroxy-5α-spirostan-6-one-3- O-α-L-rhamnosyl-(1→2)-β-D-glucoside.
[0024] (2) Use vine plants as raw materials, air-dry and pulv...
Embodiment 2
[0028] The difference between embodiment 2 and embodiment 1 is that the method for extracting the sleep-promoting components of lily,
[0029]In this example, the roots, stems and leaves of the lily plant are used as raw materials, dried naturally, crushed, extracted with ethanol or methanol, recovered the solvent, dissolved the residue in water, filtered out the insolubles, and added petroleum ether to the aqueous solution , benzene or ether and other strong lipophilic organic solvents for two-phase extraction, saponins are insoluble in these strong lipophilic solvents and remain soluble in water, while lipophilic impurities such as oils and pigments are transferred to lipophilic solvents and separated from saponins, Use butanol, which is highly hydrophilic, as the solvent to continue the two-phase extraction from the solution. The butanol solution was collected and evaporated to dryness under reduced pressure to obtain crude total saponins. Reverse column chromatography is ...
Embodiment 3
[0031] The difference between Example 3 and Example 1 is that the non-woven fabric does not contain the genus saponin extract, and the genus genus saponin extract is replaced with the lily steroidal saponin extract in equal amounts.

Abstract
The present invention relates to the technical field of paper diapers, and in particular to a non-woven fabric for sleep aid from Lily japonica and its preparation method and application. The ethanol extract of natural lily is suspended in water, and the crude saponin is extracted by water-saturated n-butanol. , and then use reversed-phase column chromatography and gel column chromatography to analyze and purify the target lily steroidal saponins; use ether as a solvent for natural night vine, ultrasonically assisted extraction, and then through ethyl acetate, n-butanol After successive extractions, the crude extract of the vine was obtained, and then the macroporous resin LS300B was used to analyze and purify the crude extract of the vine to obtain the target saponin; The woven fabric is compounded with hydrophilic and oily agents, and added to the upper and lower layers of fibers to obtain the target non-woven fabric. By applying the above-mentioned non-woven fabrics to the surface layer of diapers, the effects of natural lilies and vines on calming the nerves and helping sleep can be fully exerted to meet the needs of people with sleep disorders.
Description
technical field [0001] The invention relates to the technical field of paper diapers, in particular to a preparation method and application of a sleep-promoting non-woven fabric made of lily vine. Background technique [0002] According to the survey, the users of diapers often have difficulty falling asleep, early awakening, poor sleep and frequent awakenings at night due to their own weak body. As a personal item, diapers are in direct contact with sensitive parts of the human body. If you want to prepare diapers with sleep-promoting effects, you must choose sleep-promoting drugs that are absolutely non-toxic and side effects, and have a small amount of high-efficiency. [0003] Lily has a long history of edible and medicinal use in my country, and in recent years, there have been many reports on the sleep-promoting effect of lily, especially through the direct sleep experiment and the experiment of prolonging the sleep time of sodium pentobarbital, it has been proved that...
