Abstract
The invention relates to the technical field of paper diapers, in particular to a lily tuber fleeceflower stem sleep-aiding non-woven fabric and a preparation method and application thereof, wherein ethanol extract of natural lily is suspended in water, water-saturated n-butyl alcohol is adopted to extract crude saponin, and then a reverse phase column chromatography and gel column chromatography compounding method is adopted to analyze and purify the target lily steroid saponin; taking ethyl ether as a solvent, performing ultrasonic-assisted extraction on natural tuber fleeceflower stems, sequentially extracting the natural tuber fleeceflower stems by ethyl acetate and n-butanol to obtain crude tuber fleeceflower stem extracts, and analyzing and purifying the crude tuber fleeceflower stem extracts by using macroporous resin LS300B to obtain target tuber fleeceflower stem saponins; compounding natural plant extracts of lily saponin and tuber fleeceflower stem saponin with a non-woven fabric hydrophilic oil agent, and adding the mixture into upper and lower layers of fibers to obtain the target non-woven fabric. By applying the non-woven fabric to the surface layer of the paper diaper, the effects of soothing the nerves and helping sleep of the natural lily and the caulis polygoni multiflori are fully exerted, and the requirements of people with sleep disorders are met.
Description
Technical Field
The invention relates to the technical field of paper diapers, in particular to a preparation method and application of lily tuber fleeceflower stem sleep-aiding non-woven fabric.
Background
According to investigation, people using the paper diaper often have difficulty in falling asleep, early awakening, insufficient sleep, frequent awakening at night and the like due to weak bodies of the people. The paper diaper is taken as a close-fitting article and is directly contacted with a sensitive part of a human body, and when the paper diaper with the sleep-aiding effect is required to be prepared, a sleep-aiding medicine which is absolutely free from toxic and side effects and small in amount and high in efficiency is required to be selected in terms of medication.
The edible and medicinal history of lily in China is long, in recent years, a plurality of reports about the sleep-aiding effect of lily are provided, and particularly, direct sleep experiments and experiments for prolonging the sleep time of pentobarbital sodium prove that lily has better sedative and hypnotic effects. The main active ingredient steroid saponin of lily is a macromolecular compound with strong polarity, is not easy to crystallize, is easy to dissolve in water and alcohol, is difficult to dissolve in an organic solvent, and often has a plurality of saponins with similar structures coexisting in the same plant, which brings certain difficulty for the separation and purification of the saponins. Therefore, if the beneficial saponin in the lily can be extracted and added into the preparation of non-woven fabrics and diaper fabrics, the requirement of people suffering from sleep disorders on close-fitting care products can be met undoubtedly.
However, the extraction and application of the steroid saponins of lily in the prior patent are very rough, the extract not only can not completely remove impurity grease and polysaccharide, and can cause allergy to human body, but also has low proportion of sleep-aiding components and poor sleep-aiding efficiency. For example, patent CN201310315560.1 discloses a diaper with good water absorption, which comprises a surface coating layer, an absorption core layer and a bottom lining layer, wherein lily is heated and decocted, filtered to obtain a decoction, a biocellulose gel part is dehydrated and then soaked in the decoction, dried and dehydrated to obtain biocellulose micropowder, the biocellulose micropowder is coated to obtain the absorption core layer, and then the absorption core layer, the surface coating layer and the bottom lining layer are together prepared into the diaper; patent CN201120302826.5 discloses a traditional Chinese medicine nursing paper diaper with a surface layer and a middle layer both soaked with lily extract.
Disclosure of Invention
The invention aims to overcome the defects, applies natural plant components with the sleep-aiding function to adult paper diapers, is beneficial to relieving nerves of incontinent people and reducing sleep disorder, and provides a preparation method and application of lily tuber fleeceflower stem sleep-aiding non-woven fabric.
In order to achieve the purpose, the technical solution of the invention is as follows:
a preparation method of a lily tuber fleeceflower stem sleep-aiding non-woven fabric comprises the following steps:
(1) taking root, stem and leaf of lily as raw materials, naturally drying in the air, pulverizing, extracting with 70% -80% ethanol with volume 5-7 times of lily mass at 60-80 deg.C for 4 times, each time for 2 hr, recovering solvent ethanol to obtain ethanol extract; suspending the ethanol extract in water, extracting crude saponin with water-saturated n-butanol, and analyzing and purifying by reverse phase column chromatography and gel column chromatography to obtain natural Bulbus Lilii steroid saponin extract with purity of not less than 85%;
