Efficacy and function

1. Antioxidant effect
Oolong tea extract contains a large amount of antioxidant substances with active hydroxyl oxygen in the molecular structure such as tea polyphenols and tea pigments, which can capture excessive free radicals and terminate the chain reaction of free radicals. Oolong tea extract can improve the body's antioxidant capacity, mainly manifested in increasing plasma VC levels, increasing the activity of whole blood glutathione peroxidase and superoxide dismutase in the liver, thereby helping to remove excess free radicals in the body; In addition, it is manifested in reducing the content of lipid peroxides in the liver and serum, delaying the formation of myocardial lipofuscin, thereby delaying the aging of the human body.

2. Slimming effect
Oolong tea extract has the effect of promoting norepinephrine-induced lipolysis in adipocytes. The mechanism is that can enhance fat catabolism by inhibiting the activity of phosphodiesterase and reducing the decomposition of norepinephrine-induced cyclic AMP (cAMP).

3. Prevention and treatment of cardiovascular diseases
Oolong tea extract can reduce the concentration of low-density lipoprotein (LDL). In vitro studies also show that oolong tea can effectively delay the oxidation time of LDL and prevent the occurrence of atherosclerosis and cardiovascular and cerebrovascular diseases.

4. Inhibition of cancer
The water extract of oolong tea has direct inhibitory effect on some tumor cell lines in vitro, and shows obvious anti-tumor effect in living tumor-bearing animals. Oolong tea extracts cause developmental arrest, apoptosis, and cell cycle arrest of tumor cells at the G1 stage without affecting normal cells.

5. Beauty and skin care
The water extract of oolong tea can inhibit the activity of tyrosinase related to melanin synthesis in mouse melanoma cells, reduce the protein and mRNA levels of the enzyme, thereby inhibiting the synthesis of melanin in cells. Feeding oolong tea water extract can inhibit the increase of melanocytes, thereby whitening.

6. Regulate the efficacy of intestinal flora
The polyphenolic components present in large quantities in oolong tea extracts cannot be completely absorbed by the gastrointestinal tract, but are metabolized by intestinal bacteria in the colon, and various metabolites produced may have certain physiological functions, thereby exerting their role in regulating intestinal flora. role.
