Embodiment 1
[0019] Embodiment 1. The present invention inhibits the activity of xanthine oxidase in vitro and reduces the research of uric acid generation
[0020] Activity test: Precisely weigh cortexine hydrochloride and dissolve it with DMSO. The total reaction system was 200 μL. During the reaction, 2 μL of cortex base solution (DMSO was added to the blank group), 158 μL of buffer solution with pH 7.4, 20 μL of nitrogen blue tetrazolium solution (7.5 mM) and 20 μL of enzyme solution ( 5.4U / L) 10μL, incubate at 37°C for 3min, add hypoxanthine solution (10nM) 10μL to start the reaction, immediately measure continuously at 37°C, 560nm for 3min, and record the reaction rate. The ratio of the reaction rate of the experimental group to the reaction rate of the blank group was used as the inhibition rate of the enzyme activity.
[0021] Result: the present invention has obvious inhibitory action to xanthine oxidase in vitro (see figure 1 ), wherein the inhibitory rate of phellodine hydroch...
Embodiment 2
[0022] Embodiment 2. The present invention reduces the research of uric acid level in mice
[0023] Experimental animals: purchased from Liaoning Changsheng Biotechnology Co., Ltd.
[0024] Drugs and health care products for testing: an appropriate amount of Phellodendronine hydrochloride, dissolved in DMSO, and made into a suspension with 2.5% CMC-Na.
[0025] Grouping and administration: 60 (20-25g) of Kunming mice were randomly divided into blank group, model group, low-dose group of Phellodendronine hydrochloride (100mg / kg), middle-dose group of Phellodendronine hydrochloride (200mg / kg), Phellodendronine hydrochloride high-dose group (400mg / kg), 12 in every group. Adopt hypoxanthine potassium in combination with hypoxanthine to make a model, (hypoxanthine 300mg / kg / d, oxonate potassium 500mg / kg / d, intragastric administration), give test drug and health product (model) by intragastric administration The rats in the group were given normal saline) 1 hour later, and then giv...
Embodiment 3
[0031] Embodiment 3. The present invention reduces the research of uric acid level in rat body
[0032] Experimental animals: purchased from Liaoning Changsheng Biotechnology Co., Ltd.
[0033] Drugs and health care products for testing: an appropriate amount of Phellodendronine hydrochloride, dissolved in DMSO, and made into a suspension with 2.5% CMC-Na.
[0034] Grouping and administration: 50 SD rats (200-220g), were randomly divided into blank group, model group, low-dose group of Phellodendron hydrochloride (100mg / kg), middle-dose group of Phellodendron hydrochloride (200mg / kg), hydrochloric acid Phellodendron high-dose group (400mg / kg), 10 rats in each group. Using potassium oxonate combined with hypoxanthine to establish a model, (hypoxanthine 300mg / kg / d intraperitoneal injection, potassium oxonate 300mg / kg / d, intragastric administration), and give test drugs and health care products by intragastric administration (The model group was given physiological saline) 1 ho...
