Embodiment 1
[0017] Embodiment 1, preparation process is as follows:
[0018] (1) Get the rhizome of jasmine aerial part (except flower) and cut into small sections, dry, pulverizer breaks into coarse powder, sample weight 2.4 kilograms, be that the sodium hydroxide aqueous solution of 0.4% is soaked and extracted twice with mass concentration, each 24 hour, add 6 times the weight of sodium hydroxide aqueous solution for the first time to soak for one day, stir from time to time, release the soaking solution, add 4 times the weight of sodium hydroxide aqueous solution for the second time, operate in the same way, combine the soaking solution, and filter through three layers of gauze , get the filtrate;
[0019] (2) Take the filtrate and adjust the pH value to 3.5 with dilute hydrochloric acid, let it stand still, make the flocs deposit in the lower part, release the supernatant liquid, and obtain the lower sedimentation layer liquid;
[0020] (3) Place the lower precipitation layer obtain...
Embodiment 2
[0024] Embodiment 2, preparation process is as follows:
[0025] (1) Cut the jasmine rhizome into sections, dry it, grind it into a coarse powder with a sample weight of 2.2 kg. Soak and extract twice with a sodium hydroxide aqueous solution with a mass concentration of 0.5%, each time for 24 hours, add 7 times the weight of sodium hydroxide aqueous solution for the first time and soak for 1 day, stir from time to time, release the soaking liquid, add 5 times the weight for the second time Soak in sodium hydroxide aqueous solution, operate in the same way, combine the soaking liquid, and filter through three layers of gauze to obtain the filtrate;
[0026] (2) Adjust the pH value of the filtrate to 4.0 with dilute hydrochloric acid, leave it to stand, make the flocs deposit in the lower part, release the supernatant, and obtain the lower sedimentation layer liquid;
[0027] (3) Place the lower sediment layer solution obtained in step (2) on an electric furnace and heat to 70°...

Abstract
The invention discloses a jasmine extract with analgesia and sedative-hypnotic effects.The preparing method of the jasmine extract with analgesia and sedative-hypnotic effects comprises the following steps that firstly, jasmine rhizomes are taken, cut into sections and crushed, a 10-15-fold 0.5% sodium hydroxide aqueous solution by weight is added for soaking extraction two times, each time of extraction takes 24 h, soak solutions are discharged, filtered and combined, and a filter solution is obtained; secondly, the pH value is regulated to be 3.5-4.0, standing is carried out, supernate is discharged, a substratum precipitation layer solution is obtained; thirdly, the temperature is raised to 70 DEG and maintained for 10 min, suction filtration and washing with water are carried out, and precipitation is obtained; fourthly, 300-fold purified water by weight is added, heating and filtering operation is carried out twice according to the third step, and free jasmonate crystals are obtained; fifthly, the free jasmonate crystals are put into 100-fold ethyl alcohol by weight, a sodium hydroxide solution is added until the free jasmonate crystals are all converted into salt, and a jasmonate sodium finished product is obtained through suction filtration, washing, drying, grinding and screening.According to the preparing method, the yield of jasmonate sodium can reach 0.6%, the jasmine extract has the obvious analgesia and sedative-hypnotic effects, and the extraction technology is easy and convenient to implement and free of pollution.
Description
technical field [0001] The invention relates to the technical field of medicinal plant extraction, in particular to a jasmine extract with analgesic, sedative and hypnotic effects. Background technique [0002] Jasmine is the root, stem, and leaf of Oleaceae Jasmine, mainly distributed in Guangxi, Guangdong, Sichuan and other places. There are very few wild ones, and most of them are domesticated. They are a kind of economic crops. Use its flowers to make tea, called jasmine tea, or distill its flowers to obtain a distillate, called jasmine dew, which has the effect of relieving all stale qi in the chest, strengthening the spleen and regulating qi. Many villages and towns in Hengxian County, Guangxi have extensive planting, forming a certain scale of industry, but only use its flowers. The Jasmine Festival is held every year to promote the development of the jasmine industry. In order to develop the jasmine industry, it is necessary to increase the yield of jasmine, and th...
