EFFECT OF PERILLA FRUTESCENS EXTRACTS AND ROSMARINIC ACID ON RAT HEART MITOCHONDRIAL FUNCTIONS.

Abstract

Perilla frutescens L. due to its aromatic, antibacterial, anti-inflammatory and antioxidant traits has been traditionally used as medicinal plant in Eastern Asia. Alterations of mitochondria are interconnected with many chronic diseases. Bioactives of herbal extracts can modulate mitochondrial effects and be beneficial in prevention of mitochondrial related chronic diseases. Direct effects of the red-leaf form P. frutescens extract (PFE) and the green-leaf form P. frutescens var. crispa f. viridis extract (PCE) were evaluated investigating activities on the oxidative phosphorylation and antioxidant activity in the rat heart mitochondria in vitro. HPLC-MS analysis was applied for the identification of phenolic compounds. Cell with a Clark-type oxygen electrode was used for mitochondrial respiration measurement. The generation of reactive oxygen species was estimated in isolated rat heart mitochondria and determined fluorimetrically. State 3 respiration rate was not affected by lower concentrations, however, it was inhibited at higher concentrations by 22-70% for PFE and by 45-55% for PCE. PFE containing anthocyanins induced the concentration-dependent stimulation (by 23-76%) of the State 4 respiration rate after addition of cytochrome c due to reducing properties. Significant reduction of H₂O₂ pro- duction was observed with investigated concentrations of rosmarinic acid and both perilla extracts. Our results demonstrate that the effect of PFE and PCE extracts on rat heart mitochondria depend on the qualitative characteristics of complex of biologically active compounds. Selective effects on mitochondrial function could enable the regulation of apoptosis or another mechanisms occurring in cells.
