Neuroprotective Properties of the Standardized Extract from Camellia sinensis (Green Tea) and Its Main Bioactive Components, Epicatechin and Epigallocatechin Gallate, in the 6-OHDA Model of Parkinson’s Disease

Figure 8

The decreases in striatal DA contents (a), DOPAC (b), and HVA (c) were significantly reversed in the 6-OHDA-lesioned group, after treatments with CS (25 or 50 mg/kg), EC (10 mg/kg), or EGCG (10 mg/kg). (a) a: versus SO, ; b: versus 6-OHDA + CS25, ; c: versus 6-OHDA + CS50, ; d: versus 6-OHDA + EC10, ; e: versus SO, ; f: versus SO, ; g: versus SO, . (b) a: versus SO, ; b: versus 6-OHDA + CS25, ; c: versus SO, ; d: versus SO, . (c) a: versus SO, ; b: versus 6-OHDA + CS50, ; c: versus SO, ; d: versus SO, ; e: versus SO, ; f: versus SO, (one-way ANOVA and Newman-Keuls as the post hoc test).
