Embodiment Construction

[0012] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments.

[0013] Such as figure 1 As shown in the process flow chart, the jujube seed extract is prepared according to the following steps:

[0014] A: 3500g Semen Ziziphus spinosa is pulverized, crosses 100 mesh sieves, gets sieved Semen Semen Semen Semen Jujubee, squeezes the fatty oil through a press to obtain 367g fatty oil, fatty oil and the Semen Semen Semen Semen Semen Semen Jujube squeezed out for subsequent use;

[0015] B: decoct the Chinese jujube kernel dregs described in step A with 6 times the amount of water each time, for 100 minutes each time, filter, merge the extracts each time, and concentrate the extract to a relative density of 1.10 Add ethanol so that the alcohol content of the thick paste reaches 70%, let it stand for 12 hours, filter, and the filtrate is concentrated to a thick paste with a relative density of 1.20. Dry under re...

Abstract

The invention discloses a preparation method of a wild jujube seed extractive. The preparation method of the wild jujube seed extractive comprises the following steps: squeezing fatty oil from wild jujube seeds by using a squeezing method, decocting the rest of wild jujube seed residues with water so as to obtain an extracting solution, precipitating the extracting solution by using alcohol, concentrating, drying, crushing, sieving by using a 10-mesh sieve so as to obtain wild jujube seed dry paste powder, heating the wild jujube seed fatty oil, then adding beewax to the wild jujube seed fatty oil, fully stirring, adding the wild jujube seed dry paste powder, and uniformly milling by using a colloid mill so as to obtain the wild jujube seed extractive. The preparation method of the wild jujube seed extractive has the advantages that the wild jujube seed fatty oil is extracted by adopting the squeezing method, so that time and labor are saved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a preparation method of jujube seed extract. Background technique [0002] Suanzaoren extract is a traditional Chinese medicine preparation. According to literature reports, it has anticonvulsant effect and can increase the content of 5-hydroxytryptamine (5-HT) in the brain. The jujube seed mainly contains saponins, terpenoids, flavonoids, phenolic acids and a large amount of fatty oil. Experiments show that the average content of fatty oil in the jujube kernel is about 14%-15%. Pharmacological studies have shown that Suanzaoren oil emulsion is fed for three days, can reduce the spontaneous activity of mice, and can significantly prolong the sleep time of mice induced by pentobarbital sodium, indicating that it is an active ingredient of Suanzaoren sedative and hypnotic. Saponins, terpenoids, flavonoids and other components in Suanzaoren also have good sedative and hy...
