Objective: evaluating the effect of total anthocyanin base standardized (cornus mas L.) fruit extract on liver function, tumor necrosis factor α, malondealdehyde and adiponectin in patients with non-alcoholic fatty liver (NAFLD).
Patients are randomly assigned into 2 groups (n=40 in each group) using a software to receive total anthocyanin base standardized (cornus mas L.) fruit extract (equal to 320 mg/d anthocyanins) or placebo daily for 12 weeks.
Settings and conduct:
In a randomized double-blind clinical trial, 80 patients with NAFLD will be recruited from Diabetes Research Center, Shahid Sadoughi university of medical sciences, Yazd. The subjects are randomly divided into two groups to take total anthocyanin base standardized (cornus mas L.) fruit extract or placebo.
