and glucose transporter (GLUT) expression .

4.Antibacterial and antiviral effects:

Carnosic acid has different degrees of inhibition on Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Hansonii yeast, so that it can be used as a food preservation.

5.Growth promotion and immune system regulation: 

Carnosic acid to feed can inhibit the oxidation of lipids and proteins, extend feed shelf life, 

while having a regulatory effect on the animal's immune system, helping to reduce the risk of infectious diseases.

6.Therapeutic effect: 

Carnoic acid can inhibit the proliferation of HL-60 cells and is expected to be a new drug for the treatment of hematologic malignancies.
