Summary
(-)-Gallocatechin gallate is the polyphenol isolated from tea, with cancer-preventive activities.
In Vitro
The amount of (-)-Gallocatechin gallate does not differ in leaves of different stages, and the content is relatively low [1] . (−)-gallocatechin gallate in combination with active catechins ((−)-epigallocatechin gallate) has synergistic effects on the induction of apoptosis and inhibition of cell growth for PC-9 cells. (−)-gallocatechin gallate shows inhibitory effect on α-Glucosidase and DPPH, with IC 50 s of 30.2 μM and 12.2 μg/mL [2] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
