How to use

In Vitro:

The amount of (-)-Gallocatechin gallate does not differ in leaves of different stages, and the content is relatively low. (−)-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 IC50s of 30.2 μM and 12.2 μg/mL.
