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.

The invention belongs to the technical field of medicines, and particularly relates to a dental ulcer pasting film containing chlorophyll and a preparation method thereof. The dental ulcer pasting film containing chlorophyll is mainly prepared from chlorophyll, daucosterol, vitamin B6, ropivacaine, a film forming agent, glucoside, tributyl citrate and distilled water. The dental ulcer pasting film containing chlorophyll is reasonable and scientific in compatibility, the remarkable anti-bacteria, anti-inflammation and analgesic effects are achieved due to the interaction of the components, the state of the illness of a patient suffering from dental ulcer can be effectively relieved, and the curative time can be shortened. The dental ulcer pasting film containing chlorophyll has the advantages of being high in adhesive strength, high in dissolution rate and complete in film uncovering integrity, can effectively ensure that the medical effect is brought into play and is ideal.

The invention provides plant salt containing sea salt and aloe gelatin. The plant salt is characterized in that the plant salt contains the sea salt, the content of NaCl in the plant salt is 75-85%, the content of MgCl2 is 0.01-0.05%, the content of CaSO4 is 0.05-0.1%, the content of beta-sitosterol is 0.02-0.15%, the content of daucosterol is 0.02-0.1%, the content of an aloe anthraquinone compound is 1-2%, and the content of aloe polysaccharide is 0.5-1%. The invention further provides a method for preparing the plant salt by a heavy metal removing technology by using a nanotube. The method is characterized by comprising the step of preparing refined brine, wherein the step of preparing the refined brine comprises the step of collecting brine, adjusting the PH value of saturated brine to 7-10, and then performing precipitation for 2-5h. The brine without heavy metal ions, prepared by the method disclosed by the invention, is low in content of the heavy metal ions, the content of lead ions is 0.004mg/L or below, and the content of arsenic ions is 0.003mg/L or below.
