MYRTUS COMMUNIS L. LEAVES AND TEAS AS POTENTIAL ANTIOXIDANTS AND PROTECTORS AGAINST IN VITRO LDL-OXIDATION

摘要

Myrtus communis L. plant contained phenolic compounds, having important biological activities. In this study, using berries and leaves of Myrtus communis L. were produced teas by different production techniques (whole grains, fragmented state, berry seeds, pulverized state with different periods of infusion: 3 min, 5 min, 10 min) and their antioxidant potential were determined. The total phenolic content was determined as gallic acid equivalent (GAE), antioxidant capacity as Trolox equivalent (TEAC),the free radical scavenger capacity by DPPH method, antioxidant reducing power by FRAP analysis and low-density lipoproteins (LDL) oxidation inhibition analyzes were carried out, based on the evaluation of parameters, as the product of the highest antioxidant activity was determined pulverized tea. Principal component analysis (PCA) results supported these findings.
