Abstract

The invention discloses a preparation method of a sodium ferrous chlorophyll-ethyl cellulose microcapsule, and belongs to the field of preparation of medicinal and food pigment. The sodium ferrous chlorophyll-ethyl cellulose microcapsule taking sodium ferrous chlorophyll as a capsule core and ethyl cellulose (EC) as a capsule material is prepared by the following steps: adding sodium ferrous chlorophyll in 2% carbon tetrachloride solution of ethyl cellulose serving as a solvent, and stirring in a thermostatic water bath to prepare sodium ferrous chlorophyll suspension; adding the sodium ferrous chlorophyll suspension in petroleum ether non-solvent while stirring, continuing stirring for 1 hour, centrifuging for 20min in a centrifugal machine, washing for a plurality of times by using petroleum ether, removing supernate, spreading on the surface of a glass plate to dry in a drying oven, thus obtaining the sodium ferrous chlorophyll-ethyl cellulose microcapsule. EC serving as the capsule material has stable physical property and chemical property and extreme low toxicity; the microcapsule prepared from EC and other auxiliaries in a certain proportion has obvious sustained release effect, the effective blood concentration can be maintained for a long time, the microcapsule facilitates the patient, and the therapeutic effect of the medicine is guaranteed.

Description

technical field [0001] The invention relates to a preparation method of sodium iron chlorophyllin-ethyl cellulose microcapsules, belonging to the field of preparation methods of medicinal and food pigments. Background technique [0002] Sodium iron chlorophyllin (including iron (II) chlorophyllin and iron (III) chlorophyllin) is easily soluble in water or dilute alcohol solution, but insoluble in oils and fats. After research and testing, the sodium iron chlorophyllinate solution is stable against indoor light, but its stability against outdoor natural light is not ideal. In addition to being a good food coloring, sodium iron chlorophyllin can also be used as an iron fortifier in medicine. Shengxuening tablets made of sodium iron chlorophyllin have been successfully used in the treatment of iron deficiency anemia. This is the only dosage form of iron chlorophyllin sodium salt in China. Utilizing the characteristics of microcapsules, the further microencapsulation treatment...
