Abstract
The invention relates to a preparation method of a phloretin pellet, which is simple, convenient and easy to operate. The preparation method overcomes the shortcomings in the prior art, and phloretin is prepared into a pellet type product with controllable release in the body and high bioavailability, so as to better meet the demands of general consumers. In the preparation method, the phloretin is ground into fine powder by adopting micronization technology, and the average particle size of the fine powder is generally less than 15 um and mainly distributed in the range of 5-20 um. By adopting the preparation method, the absorption rate of effective ingredients is increased, and the bioavailability is improved; and by adopting water-soluble adhesive and excipient, the solubility of the phloretin in the body is greatly enhanced, and as the solubility of the micron-sized effective ingredients in the gastrointestinal tract is significantly increased, the bioavailability of the micron-sized effective ingredients is increased, and the onset time of the micron-sized effective ingredients is shortened.
Description
Technical field [0001] The invention relates to the technical field of medicine and food, in particular to a phloretin pellet and a preparation method thereof. Background technique [0002] Phloretin is a natural active substance found in apples, pears and other fruits and a variety of vegetable juices. It is named only because of the relatively concentrated content in the rhizomes or root barks of these plants. Phloretin can activate cellular protein kinase, which is effective for disordered cell proliferation. It is an anti-mutagenic factor in food and can be used for the treatment of skin cancer and other tumors. It has strong anti-oxidation properties, and its antioxidant concentration against oils Between 10 and 30PPm; external use can prevent carbohydrates from entering epidermal cells, thereby inhibiting excessive secretion of skin glands, treating exuberant acne; inhibiting the activity of melanocytes, and diminishing various skin spots. [0003] At present, phloretin prod...
