51 results about "Silybum Marianum Seed" patented technology

Silybum marianum seeds contain concentrated amounts of a unique group of flavonoids and flavonolignans collectively called silymarin. Silymarin is thought to be the most therapeutically active ingredient of milk thistle. Although concentrated in the seeds, silymarin is also contained throughout the milk thistle plant.

Method for preparing silybin

The invention relates to a method for preparing silybin. The method comprises the following process steps: crushing silybin seeds into 20 to 40 meshes, and degreasing the crushed silybin seeds thrice by using n-hexane; refluxing and extracting degreased coarse materials by using dilute ethanol; concentrating the extract under reduced pressure till the extract has no ethanol smell, extracting the concentrate by using ethyl acetate, stirring and drying ester phase and silica gel, then injecting a dried product to a column, eluting the dried product by using benzene or benzene-ethyl acetate, collecting the elute by sections, combining the elute to obtain main elute component of the silybin, concentrating the elute under reduced pressure, dissolving the elute in ethanol solution, adding active carbon into the solution, stirring the solution, decolorizing the solution for 0.5 to 1 hour, filtering the active carbon from the decolorized solution, concentrating the decolorized solution under reduced pressure to 40 to 60 percent of the primary volume, cooling the concentrate to separate out crystals, crystallizing the crystals by using hot ethanol, and repeating the crystallization step for 2 to 4 times to obtain the silybin. The method for producing the silybin has the advantages of simple process, low solvent toxicity, low production cost, and easy realization of industrialization.

New method for purifying silymarin

The invention belongs to the field of natural organic chemistry, and relates to a method for preparing high purity silymarin by the following steps: adopting biological wall breaking and microwave pretreatment to obtain oil, carrying out microwave countercurrent extraction and macroporous resin purification to obtain the high purity silymarin. The method has the following advantages that: 1, a step-by-step method is adopted to carry out degreasing, seeds are pretreated, microwave countercurrent extraction is performed, and isoelectric point precipitation is performed to remove proteins, such that complete dissolution of effective components of the silymarin is prompted; 2, with the microwave extraction, the extraction time is reduced to 60-80 minutes so as to improve extraction speed and increase effective component content, and reduce herb consumption and energy consumption; 3, the macroporous resin adsorption technology is adopted so as to reduce the amount of the solvent, and the macroporous resin can be conveniently and rapidly regenerated, such that the cost is substantially reduced; and 4, two products of silybum marianum oil and silymarin can be obtained. With the method, the biological wall breaking treatment is performed on the silybum marianum seeds at the early stage so as to shorten the microwave pretreatment time, such that the seed oil can be extracted in just a few minutes; with the two-step microwave extraction, the extraction time is shortened; and the disadvantages of long conventional extraction time, low extract purity and single extract are overcome.

Method for refining silybum marianum seed oil by enzymic-method degumming

The invention discloses a method for refining silybum marianum seed oil by enzymic-method degumming and relates to the technical field of oil refining. The method includes the following steps: squeezing or leaching silybum marianum seeds to prepare silybum marianum seed oil, utilizing the principle that suspension impurities and oil have different densities to separate the impurities and the oil under the standing state or placing the silybum marianum seed oil into a 50 DEG C drying box for 1h, filtering to prepare crude oil, degumming the silybum marianum seed oil through phospholipase and conducting deacidification, decoloration and deodorization to obtain the refined silybum marianum seed oil. The enzymic-method degumming method adopts key technology for refining of the silybum marianum seed oil, remarkably reduces phospholipid content in the degummed silybum marianum seed oil, and is high in degumming efficiency, mild in reaction condition, low in energy consumption and easy to control. Silica gel is utilized as adsorbent to conduct decoloration and deodorization processing, high temperature vacuum decoloration and high temperature vacuum deodorization processing in the prior art are avoided, loss of effective components in the silybum marianum seed oil is reduced, and process flow is shortened.

Method for improving dissolution of effective ingredients of silybum marianum shells

The invention provides a method for improving dissolution of effective ingredients of silybum marianum shells. The method comprises the following steps: adding water in silybum marianum seed shells and stirring, and then stopping stirring and moistening to enable the silybum marianum shells to fully absorb water and then to be in a softened state; enabling the moistened silybum marianum shells to pass through a spiral rolling and separating device to enable the water content in the shells to be controlled to be 5% or below so that scattered silybum marianum seed shells are changed into spiral shell strips; feeding the shell strips into a closed high-frequency microwave drying device through a conveying belt and drying for 2-3 minutes, controlling water to be 3% or below, and keeping the shell strips spiral to obtain the treated silybum marianum shell strips; and (4) carrying out solvent extraction on the treated silybum marianum shells according to the conventional method. The general flavone is extracted by the silybum marianum seed shells, the feeding amount of the treated silybum marianum seed shells treated by the same extracting equipment is two times greater than the original feeding amount, the energy consumption is halved, the relative production period is also halved, and the yield of the general flavone of the silybum marianum relative to shells is improved by about 2%.
