The invention relates to the technical field of traditional Chinese medicines, in particular to a
uric acid reducing composition and a preparation method thereof. The
uric acid reducing composition is prepared from 35 to 45 parts of a
cyclodextrin inclusion compound, 25 to 35 parts of nano-
liposome, 20 to 30 parts of a chicory extract-
phospholipid compound and 5 to 8 parts of an
antioxidant compound, the preparation method of the
cyclodextrin inclusion compound comprises the following steps: step 1, adding beta-
cyclodextrin into water, stirring and dissolving, adding a radix puerariae extract, and
drying after inclusion reaction to obtain an
inclusion compound a; 2, hydroxypropyl-gamma-cyclodextrin is added into water, stirring is performed, the
mulberry leaf extract is added,
drying is performed after inclusion, and an inclusion compound b is obtained; and step 3, mixing the
clathrate compound a and the
clathrate compound b to obtain the compound. The
uric acid reducing composition provided by the invention can be used for more comprehensively and efficiently reducing the
blood uric acid level, and is high in safety, strong in stability and high in
bioavailability. The preparation method is simple, convenient, easy to industrialize and beneficial to large-scale industrial production.
