Application of daucosterol in preparing medicines for promoting proliferation of neural stem cells

The invention relates to a new application of daucosterol in medicine and health care product preparation, in particular to application of daucosterol in preparing medicines and health care products for promoting proliferation of neural stem cells. The daucosterol is a phytosterol derivative and is sitosterol-3-O-glucoside which widely exists in plants, and the processes of extracting, separation and content detection are simple and convenient. According to research, the medicines can promote proliferation of osteoblastlike cells, protect endothelial cells of human capillaries and further can reduce blood sugar activity. By means of the application, primarily-cultured neural stem cells and aged mice serve as the materials, and users can observe the effect of daucosterol on the neutral stem cells. In-vitro experiments and integral experiments prove that the daucosterol has the effect of promoting proliferation of the neutral stem cells. In the in-vitro experiments, the daucosterol with the dose ranging from 10 mu mol / L to 100 mu mol / L can promote proliferation of the neutral stem cells, and in the integral experiments, the daucosterol with the dose of 10mg / kg can promote proliferation of the neutral stem cells of the aged mice.

Animal feed processed by aid of ginkgo biloba sarcotesta and method for preparing animal feed

The invention belongs to the field of agricultural breeding, and particularly relates to animal feed processed by the aid of ginkgo biloba sarcotesta and a method for preparing the animal feed. The animal feed processed by the aid of the ginkgo biloba sarcotesta is made of the ginkgo biloba sarcotesta. The method includes repeatedly extracting the ginkgo biloba sarcotesta by the aid of organic solvents to remove ginkgolic acid which is a toxic substance in the ginkgo biloba sarcotesta; centrifugally washing the ginkgo biloba sarcotesta to remove the residual organic solvents to obtain the animal feed. The animal feed and the method have the advantages that the residual quantity of the ginkgolic acid in the animal feed made of the ginkgo biloba sarcotesta is lower than 10 mg/kg, and the residual quantity of the organic solvents is lower than 0.5 wt%; the ginkgo biloba sarcotesta contains abundant starch, polysaccharides, amino acid, diversified vitamins and proteins, further contains small quantities of ginkgo flavone, terpene lactones, daucosterol and diversified trace elements and is processed to obtain a ginkgo biloba sarcotesta feed additive, the ginkgo biloba sarcotesta feed additive can be used for breeding animals, and accordingly effects of preventing and treating diseases, protecting health and promoting growth of livestock can be realized; food can be saved, environments can be cleaned, pollution can be reduced, and requirements of the modern breeding industry on environmental friendliness, environmental protection, safety and zero pollution can be met.

Method for extracting shelled cedar seed oil and daucosterol from shelled cedar seed

The invention relates to a method for extracting shelled cedar seed oil and daucosterol from shelled cedar seed. The method comprises the following steps of: shattering shelled cedar seed, extracting with petroleum ether twice to obtain shelled cedar seed oil, completely volatilizing the petroleum ether from the cedar seed after extracting the shelled cedar seed oil, extracting with ethanol twice, mixing filtrate, recycling the ethanol to enable the mixed filtrate to form extract, adding column chromatography silicon gel which is 1-4 times the weight of the extract, uniformly stirring, drying in a drying box, and cooling to obtain column layer silicon gel mixture, packing column chromatography silicon gel which is 4-8 times the weight of the extract into the chromatography column with a petroleum ether wet method, adding the column layer silicon gel mixture into the chromatography column, eluting with petroleum ether and acetic ether the volume ratio of which is 1:1 until effluent liquid is almost colorless, replacing the eluting liquid with acetic ether, mixing acetic ether eluting liquid, and recycling the acetic ether to obtain crude daucosterol. The invention has simple and convenient technological method for preparing daucosterol, low virulence of extracting and eluting solvent, high purity of the daucosterol, little impurity and easy purification, and is suitable for preparation or production in large scale.
