Green tea inhibition of SULT1A1 using 4-nitrophenyl as the substrate

Inhibition was detected.  Cutoff used — Not available

p-nitrophenol

green tea leaf

4-nitrophenyl sulfate

  • SULT1A1

Recombinant expression system E.coli
Cytochrome B5 No

Results

The above results were observed at concentrations of 5 and 10%. At green tea 1%, p-nitrophenol sulfation was significantly inhibited by approximately 90% (estimated from Fig. 4A; P < 0.01).
